The significance of a lower than normal hematocrit indicates the percentage of total red blood cells is below the lower limits of normal for that person’s age, sex, or specific condition. The cause can be anemia which is a lower than normal number of red blood cells. Other factors that can cause lower than normal hematocrit is bleeding, destruction of a red blood cells, leukemia, malnutrition, and over hydration. (Medline Plus Anemia, 2013). The effect of a bacterial infection on the hematocrit means the white blood cell count is elevated. Above normal white blood cells indicates an infection.
Comparison of the development of lymphocytes with the development of the other formed elements. The process of development is called hemopoiesis and it occurs mainly in red bone marrow after birth. Red bone marrow cells contain pluripotent stem cells that have the ability to develop into many different types of cells. Myeloid stem cells begin and complete their development in red bone marrow and turn into red blood cells, platelets, mast cells, eosinophils, basophils, neutrophils, and monocytes. Lymphoid stem cells begin their development in red bone marrow but are completed in lymphatic tissues, where they rise to lymphocytes and natural killer cells. (Jenkins, Kemnitz, Tortora, 2013).
Erythropoiesis is the production of red blood cell formation. It speeds up when oxygen is delivered to the kidney and other tissues. It slows down when there is a decrease in oxygen carrying capacity of blood. The cellular oxygen deficiency occur if too little oxygen enters the blood. (Jenkins, Kemnitz, Tortora, 2013).
If a person with type B blood were given a transfusion of type O blood there will be no reaction. People with type O blood have neither A or B antigens on their red blood cells and are called the universal donor. Since type O have…...

...standards in school curricula, she strongly encourage that education should be mainly focus on “growth of competent, caring, loving, and lovable people”, in her words, which are more suitable for today’s schools in 21 century. It was very impressive that at the first part of the article, Nel Noddings raise a question of “What do children need for education”, follow on the national answer of children need more on the “academic training” which will benefits for both satisfying countries’ needs and safe them from “poverty, crime, and other evils of current society”. Ironically, this is my third college year and I forgot most of what I have learned from my mathematics and sciences teachers, of course, I have no contribution to the society, and my country doesn’t has a strong need on me. Moreover, I am not in that kind of poverty which needs someone to save me from an impoverished situation, I did no crime, and not that evil to the society except sometimes I do not pay quarters for parking. With Nel Noddings idea, she against an ideology of “control that forces all students to study a particular, narrowly prescribed curriculum devoid of content they might really care about”. Her words go deeply into my heart and I think I found an educator who understands me to some extent. Let me recall when I would have to use mathematics in my life recently. It was this evening I calculate the 15% tips that I have to pay, yesterday I went to Publix and figured out by counting days when......

The overall culture of the attitude towards the employee, how they interact, fit in, encourage or discourage their co-workers, and the overall dynamic of their presence in the organization.  By keeping the more motivated employees, that usually is comprised of the younger generation of the employee pool • Considering I have to answer the question I will provide explanations for both being “let go.”  If the company is looking to keep young energetic employees, and might be planning on moving into a new office style in the future they have to let go of Mary.  If the company is not planning on changing their office style they have to let go Sarah.  Keep in mind they both have strong attributes to bring to the table.  Sarah is trying to prove herself by stepping up to volunteer her services, but she is young and may find something more appealing to her and leave anyway.  Maybe Sarah finds a job in San Diego she is young and energetic, she may move away.  Then the company is finding itself having to rehire.

Whats About Alcohol

...Alcohol is not only the reason why prohibition took place in the 1920s, but it is also the reason why many persons wake up not remembering their pervious night’s endeavors. It has always been evident that alcohol has an effect on brain function, which in-turn impairs the behavior of a person. Alcohol can be separated into two separate groups: what is expected to happen, and what actually happens. Alcohol is expected to play social lubricant and aphrodisiac. When it comes to being social alcohol does seem to have a loosening effect on people, however, it is almost the opposite sexually. Alcohol actually acts as more of a suppressant when sex is brought into the picture. It has only be known to be a sort of aphrodisiac because that is the way it is perceived and that is the way in which people choose to perceive it. Given the choice between two women, one holding an alcoholic drink and the other not, a man will more often pick the women with the alcoholic drink due to the fact that alcohol is a precursor to the possibility of having intercourse. Introduction Alcohol can be traced back to ancient times when Egyptians used beer and wine for ritual and celebratory purposes (Hanson 1995). Osiris, the god of wine, was praised throughout the entire land of Egypt. The Egyptians believed that this important god also invented beer, a beverage that was considered a necessity of life and was brewed in the home. Both beer and wine were created for and sacrificed to the gods.......

...Activity 1: Tell Me about Blood Low hematocrit levels, AKA anemia, indicate a low percentage of red blood cells in the blood. The effect of a bacterial infection would be a decrease in hematocrit levels. Leukocytes can be formed in several locations thought the body. The thymus, bone marrow, and spleen all produce leukocytes. The other formed elements are developed through red blood cells or fragmentation of megakaryocytes in the bone marrow. Erythropoiesis is the formation of red blood cells. Erythropoiesis speeds up when oxygen delivery to the kidneys is reduced. This triggers a negative feedback system that speeds up the process until kidney oxygen levels return to normal. Type O blood is known as the universal donor because any other blood type can safely receive a transfusion, with no negative effects from this type. If a person with B blood received a transfusion of O blood everything would be fine. A. This WBC is a lymphocyte. Its primary function is producing antibodies. T lymphocytes attack infected or cancerous cells. B. This WBC is a basophil. Its primary function is to help mediate inflammation C. This WBC is a monocyte.

...Unit 1 Case Study 1: Tell me about blood. 1. Lower than normal Hematocrit indicates Anemia. Hematocrit does not have enough Hemoglobin which is an oxygen carrying protein in red blood cells that results in having Iron, B12 and Folic Acid deficiencies. The main causes of developing Anemia include: medications and pregnancy, but the more serious causes include: kidney disease and cancer of the kidney, also leukemia and lymphoma. A bacterial infection on the Hematocrit can cause the white blood cell count to raise but lower Hematocrit. 2. Lymphocytes and other formed elements develop from Pluripotent cells. Pluripotent stem cells generate Myeloid and lymphoid stem cells. The Myeloid stem cells starts and completes development in red bone marrow and raises red blood cells, Platelets Eosinophils, Basophils, Neutrophils and Monocytes. The Lymphoid stem cells develop in red bone marrow but complete in the Lymphocytes tissue. 3. Erythropoiesis is the production of red blood cells or Erythrocytes. It slows down when there is a decrees in oxygen carrying capacity of blood but speeds up when oxygen is delivered to the kidneys and other tissue foils. 4.

...Tell Me about Blood Lucrezia Stoner ITT, Strongsville Tell Me about Blood 1) A lower than normal hematocrit or anemia means that the percentage of red blood cells is below the lower limits of normal. It could be as a result of internal bleeding, nutritional problem or over hydration. 2) When there is a bacterial infection, the hematocrit is raised. Lymphocytes are types of white blood cells. They are the body’s primary immune defense and move through the lymph in response to antigens and pathogens. T-cells originate in the bone marrow and migrate to the thymus to mature; B-cells also originate in the bone marrow and migrate to the lymph tissues to mature. 3) Erythropoiesis is the production of red blood cells. This process begins with myeloid cells that differentiate into myoblasts (an immature white blood cell of the bone marrow) orproerythrocytes (an immature red blood cell). There are several factors which influence and regulate erythropoiesis: Erythropoietin- (EPO) a hormone secreted by the kidneys which stimulates the bone marrow to increase differentiation of proerythrocytes and thus increase erythrocyte production. Intrinsic factor- or erythrocyte-maturing factor, which the stomach secretes to facilitate erythrocyte maturation. Vitamin B12- also called the extrinsic factor, which interacts with the intrinsic factor. Iron- an essential component of hemoglobin (the protein complex within erythrocytes that binds with oxygen) 4) A person with type O......

...Assume that a 13 year old is studying blood in school, but has questions that haven’t been answered in class. These are some of the questions he asked you. Write a paragraph to answer his questions in language that will be understandable by a young teenager. 1. What is the significance of a lower than normal hematocrit? What is the effect of a bacterial infection on the hematocrit? A significant drop in the hematocrit indicates anemia, a lower than normal number of red blood cells (RBCs). Lower values in women during their reproductive years also may be due to excessive loss of blood during menstruation. A bacterial infection would increases the production the number of White Blood Cells (WBC), because the WBC are fighting off the infection may affect the hematocrit by lowering it. 2. Compare the development of lymphocytes with the development of the other formed elements? Lymphocytes: produced in red bone marrow but lymphocytes can also be produced in lymphatic organs such as lymph nodes and spleen. Develop from lymphoid stem cells. B cells: Attack bacteria, viruses and toxins T cells: Acting directly against virus-infected cells and tumor cells Leucocytes: Only formed elements that are complete cells with a nucleus and usual organelles Develop from myeloid stem cells.

...Case Study 1: Tell Me About Blood ITT Technical Institute Navid Momeny Case Study 1: Tell Me About Blood 1. What is the significance of lower-than-normal hematocrit? What is the effect of a bacterial infection on the hematocrit? A lower-than-normal hematocrit tells us that a person has anemia. A large amount of white blood cells due to cancer or some type of infection, vitamin or mineral deficiencies, or some type of blood loss. A bacterial infection will cause the hematocrit test show more white blood cells in the blood because it is trying to fight off the infection. 2. Compare the development of lymphocytes with the development of the other formed elements. Lymphocytes are produced in the red bone marrow and some can be produced in lymphatic organs like the lymph nodes. B cell lymphocytes are in the red bone marrow where they live out their life cycle. T cell lymphocytes begin in the red bone marrow but later mature in the thymus. 3. What is erythropoiesis? Which factors speed up and slow down erythropoiesis? Erythropoiesis produce red blood cells. The amount of oxygen being carried would affect the speed of erythropoiesis. 4. Explain what would happen if a person with type B blood were given a transfusion of type O blood. A person that has type B blood can receive a transfusion from a person with type O blood because there are no antigens and the person with B blood will not have any antibodies that will attach the O blood. 5.

...Tell Me About Blood Dayna Fultz December 12, 2015 ITT Technical Institute 1. What is the significance of a lower-than-normal hematocrit? What is the effect of a bacterial infection on the hematocrit? First, hematocrit is the percentage of blood made up of red blood cells. This is usually measured by centrifuging a blood sample in a graduated tube. Then, reading the volume of red blood cells and dividing it by the total volume of blood in a sample. A significant drop in hematocrit is an indication of anemia (lower-than-normal number of red blood cells. A bacterial infection would increase the production of white blood cells to fight off the infection. The hematocrit would have a thicker buffer layer causing the red blood cell production to slightly decrease which would decrease the ratio of red blood cells to whole blood volume. 2. Compare the development of lymphocytes with the development of the other formed elements. Lymphocytes and the other formed elements are developed from pluripotent stem cells. The pluripotent stem cells generate myeloid stem cells and lymphoid stem cells. Myeloid stem cells start and complete their development in red bone marrow and give rise to red blood cells, platelets, eosinophils, basophils, neutrophils, and monocytes. Lymphoid stem cells begin development in the red bone marrow, but some are completed in the lymphatic tissues, where they give rise to lymphocytes. The B cell lymphocytes begin and finish in the red bone marrow and the......

... Unit 1 Case Study 1: Tell Me about Blood Christie Wolford Breckenridge School of Nursing The normal range of hematocrit (percentage of total blood volume occupied by red blood cells) is 38-46 for (average) females and 40-54 in (average) males, a lower than normal hematocrit indicates anemia; a less than normal percentage of red blood cells occupying the blood volume, red blood cells carry oxygen. When there is a low hematocrit that means that there is not enough oxygen being circulated throughout the body because there are not enough red blood cells. When there is a bacterial infection the hematocrit are not affected, red blood cells are transporters, not defenders. Hematocrit is only the percentage of red blood cells contained within a sample and no other cells. The bacterial infection will cause there to be an increase of white blood cells, as they are the ones on the “front line” of invasion protection. (Jenkins, Tortora, 2013) Unlike red blood cells; white blood cells have nuclei and a full set of other organelles, but no hemoglobin. (this is a given as hemoglobin is what gives red cells their color)Lymphocytes are agranular leukocytes, meaning they possess cytoplasmic granules. All formed elements develop from pluripotent stem cells, however lymphocytes derive from lymphoid stem cells rather than myeloid stem cells. Lymphoid stem cells begin development in the red bone marrow and complete it in lymphatic tissues creating lymphocytes and natural killer cells.......

Writing About What Matters

...Writing about What Matters Martin Luther King gave the “I Have A Dream…” speech where he proclaims that it is time to cash a check that has long been due to them. It is not money that is wanted it is a demand to have the riches of freedom and the security of justice. King brings up things that should no longer be satisfied by the colored population. By listing these things King brings out the faith in people to take action and make the changes that are needed. The ending of this speech brings the message of freedom for all not just blacks. President Obama spoke on the 50th anniversary of the March on Washington sharing how much King influenced the changes that were made following his speech. Obama spoke about how through all the hatred a nonviolent path was taken in order to get this freedom. Finding courage within others and ourselves is what leads us to be able to move forward and make a difference in the future. At the end of Obama’s speech he says that the promise of tomorrow comes from the lessons of the past. A country can only change its ways because of the love from the people. The dream has changed over the past 50 years to become something even bigger. There is so much more diversity in America today and more people share the same struggles. The vision changed to become more than just a fight for equality for blacks but for everyone who is struggling for the freedom to be themselves. These visions could not be added to or changed. They represent what two......

...Tell Me about Blood Paige Keegan March 24, 2016 ITT-Technical Institute 1. How does the volume of blood in your body compare to the volume of fluid in a two-liter bottle of soda? In the average-sized male the blood volume is 5-6 liters and 4-5 in the adult female. (Pg. 616) 2. What is the significance of a lower-than-normal hematocrit? A higher-than-normal hematocrit? Lower-than-normal hematocrit indicates anemia. Higher-than-normal hematocrit indicates polycythemia. (Pg. 619) 3. How is the development of lymphocytes unique when compared to the development of the other formed elements? B Lymphocytes develop in red bone marrow, T lymphocytes develop in red bone marrow and mature in the thymus; the other formed elements develop in red bone marrow. 4. How are red blood cells able to squeeze through capillaries that are smaller in diameter than they are? The cell membrane is strong and flexible, so it can deform without rupturing the cell. (pg. 622) 5. Why do red blood cells live for only about 120 days? Because of the wear and tear their plasma membranes undergo as they squeeze through blood capillaries. (pg. 622) 6. What is erythropoiesis? What factors speed up and slow down erythropoiesis? Erythropoiesis is production of RBCs. Erythropoiesis is speeded up when oxygen delivery to the kidneys falls and slows down when there is sufficient oxygen-carrying capacity of the blood. (pg. 624) 7.

...Tell me about Blood Assignment GE259 Tell Me About Blood 1) A hematocrit is a blood test that measures the percentage of red blood cells in the total volume of whole blood. So a lower than normal hematocrit would mean that you have a lower than normal RBC’s (red blood cell) count for your age, sex, or condition. This signifies that you could have anemia, internal bleeding, or something is destroying your RBC’s, or your body is not producing them at an appropriate rate. The effect of a bacterial infection on a hematocrit would be that you would have a lower RBC count because you will have a higher WBC’s (white blood cell) count to combat the bacterial infection. 2) Leukocytes are produced and stored in different locations like the thymus, spleen, and bone marrow. There are two kinds of lymphocytes B lymphocytes and T lymphocytes (killer T cells). Lymphocytes start out in the bone marrow and either stay there to mature into B cells, or they leave for the thymus gland, where they mature into T cells.  Formed elements, such as blood is a mixture of plasma and other substances which are developed through erythrocytes. Platelets are formed by the fragmentation of megakaryocytes. 3) Erythropoiesis is the production of RBC’s. This begins in the red bone marrow and starts off as a proerythroblast. The proerythroblast then divides several times until it reaches the end of development and ejects the nucleus. After that it is called a reticulocyte. The reticulocyte...
