Unit 1 Case Study

In this paper I will answer some questions about blood and related issues. Some of the questions I will answer are: what is the significance of a lower than normal haematocrit? what is erythropoiesis?why would the level of leukocytes be higher in an individual who has been infected with a parasitic disease. In regions where malaria is endemic, some people build up immune resistance to the malaria pathogen. Which WBCs are responsible for the immune response against pathogens? How do they function?
A 13 year old is studying blood in school, and has asked some questions that haven't been answered in class. I will answer these questions In a way that a young teenager would be able to understand.
What is the significance of a lower than normal hematocrit ? What is the effect of a bacterial infection on the haematocrit? A test called haematocrit is the testing of the proportion of red blood cells compared to all blood cells in a certain volume. A lower than normal finding on a hemotocrit could mean anemia, a large number of white blood cells due to illness infection Leukemia, Lymphoma or other white blood cell disorders, vitamin or mineral deficiency or recent blood loss. The effect of a bacterial infection on the hemotocrit would cause a decrease of the haematocrit.
Compare the development of lymphocytes with the development of other formed elements. There are two kinds of lymphocytes, B lymphocytes and T lymphocytes. Lymphocytes begin in the bone marrow, if they stay there then they are B lymphocytes, if they move to the thymus they are called T lymphocytes. The other formed elements of blood start with a mixture of plasma that develop through erythrocytes and the platelets are formed by megakaryocytes exploding.
What is erythropoesis? Which factors speed up and slow down erythropoesis? Erythropoesis is the process of making new red blood
