General increase in red blood cells (erythremia). 2. Excess iron deposits throughout the body 3. Hereditary condition characterized by abnormal crescent shape of erythrocytes and by destruction of red blood cells 4.

A Schematic Model of Red Blood Cell Production The following problem deals with the number of red blood cells (RBCs) circulating in the blood. Here we will present it as a discrete problem to be modeled by differ- ence equations, though a different approach is clearly possible. In the circulatory system, the red blood cells (RBCs) are constantly being de stroyed and replaced. Since these cells carry oxygen throughout the body, their num. ber must be maintained at some fixed...

Question 31 6 pts 16) Some patients with erythrocytosis (excess Red Blood Cells) have a mutation that converts a Lysine to Alanine at residue 82 in the beta-subunit of hemoglobin. This particular Lysine normally protrudes in the central cavity of deoxyhemoglobin, where it participates in binding 2,3,-bisphosphoglycerate (BPG). What effect would you predict this mutation will have on a) the affinity of hemoglobin for BPG and for b) the affinity of hemoglobin for Oxygen in patients with erythrocytosis? Briefly explain...

19. A hemoglobin reflects the amount of oxygen-carrying potential available in the blood. 20. Anemia is any decrease in the oxygen-carrying ability of the red blood cells (RBC). 21. Sickle cell anemia is curable. 22. Pernicious anemia is due to a lack of intrinsic factor leading to inadequate absorption of vitamin B12- 23.

Practice Questions 61 15. A patient had a bone marrow transplant and numerous blood transfusions during the course of treatment for cancer. A bone marrow biopsy performed to monitor for recurrence a few weeks after treatment ended, showed abundant hemo siderin within macrophages. In this case, hemo- siderin accumulation is not likely due to A. deposition of immunoglobulin light chains produced by the patient's cancer. B. brown atrophy. C. excess dietary lipid. D. iron overload from blood transfusions. 16. Which...
