Activity 1 - Hematocrit Determination 1. List the hematocrits for the healthy make (sample 1) and female (sample 2) living in Boston (at sea level) and indicate whether they are normal or whether they indicate anemia or polycythemia. Healthy Male (Sample 1) = 48 and Healthy Female = 44. Both are normal as the average hematocrit for males is 42-52%, and the average for females is 37-47% 2. Describe the difference between the hematocrits for the male and female living in Boston. Why does this difference between the sexes exist? Men have a higher hematocrit due to 1.) being larger in size than women and having more muscle mass, and 2.) It has been shown that testosterone affects the secretion of erythropoietin (EPO) by the kidneys. EPO is†¦show more content†¦THE DIFFERENCE IS THAT THE MALE HAD A HIGHER HEMATOCRIT VALUE THAN THE FEMALE. BATH ARE WITHIN NORMAL RANGE, BUT NORMALLY A MALE WILL HAVE HIGHER HEMATOCRIT LEVELS. 3. Activity 1: Hematocrit Determination HEMATOCRIT VALUE FOR HEALTHY MALE LIVING IN DENVER. HEMATOCRIT VALUE FOR HEALTHY FEMALE LIVING IN DENVER. MALE = 55 FEMALE = 53 4. Activity 1: Hematocrit Determination HOW WOULD THE VALUES OF DENVER DIFFER FROM BOSTON. THERE BOTH WITHIN NORMAL LIMITS, BUT BOTH ARE INCREASED (ELEVATED) COMPARED TO THE MALE AND THE FEMALE FROM BOSTON. 5. Activity 1: Hematocrit Determination DESCRIBE THE EFFECT OF LIVING AT HIGH ELEVATIONS ON A PERSONS HEMATOCRIT. THE EFFECT WOULD BE THAT A OERSON CAN GET POLYCYTHEMIA WITH IS A SIGNIFICANT INCREASE IN RED BLOOD CELLS. 6. DESCRIBE HOW THE KIDNEYS RESPOND TO A DECREASE IN OXYGEN AND WHAT EFFECT THIS HAS ON HEMATOCRIT. IN RESPONSE TO DECREASED BLOOD OXYGEN, THE KIDNEYS RELEASE ERYTHROPOIETIN INTO BLOODSTREAM. INCREASED ERYTHROPOIETIN STIMULATES RBC PRODUCTION IN RED BONE MARROW, THIS PROCESS INCREASES BLOOD OXYGEN LEVELS, RESTORING HOMEOSTASIS. WHICH WILL INCREASE HEMOTOCRIT. 7. HEMATOCRIT VELUE FOR MALE WITH APLASTIC ANEMIA. % WBC FOR MALE WITH APLASTIC ANEMIA. WHERE THE VALUES WITHIN THE NORMAL RANGE? WHY OR WHY NOT? HEMATOCRIT VALUE = 19 % WBC = 0.5% NO, THE VALUES WERE WAY BELOW THE NORMAL RANGE. BECAUSE THE PERSON HAS APLASTIC ANEMIA WHERE THE BONE MARROW FAILS TO PRODUCE ADEQUATE
