(1 pt) 28. What is hematopoiesis? (1 pt) 29. A woman was in a serious car accident and needs blood. She does not have a blood card but you do a standard blood test and find this. (6 pts) What antigens are present on her blood cells? What antibodies are present in her plasma? A B RH What types of blood can she receive? 30. A man and a woman have a child with blood type O blood. Forgetting about RH what are the possible blood types of the mom and dad? (more than one can be correct) (3 pts) a. IAi b. IAIA c. IBi d. IBIB e. IAIB f. ii 31. A man with type IAi blood and a woman with type IBi blood want to have a child. What are the chances of having a type IAi child? Draw a punnet square. (5 pts) Choose 3 out of the 4 of the following to complete. Do the 4th for extra credit. Make sure to announce which is the extra credit one. Complete on a separate sheet of paper. This is a take home portion of the test. Please do it on your own. You may use resources but not another person. (5 pts each) due Wednesday march 3rd when you come to class. Describe the three phases of the normal blood-clotting process. Describe ABO and Rh blood groups. Trace the path of a drop of blood, starting at the right atrium and returning to the right atrium, through the pulmonary and systemic circuits of the cardiovascular system. Identify the chambers, valves, and vessels (except specific systemic blood vessels that are not directly associated with the heart), and indicate whether the blood is oxygenated or deoxygenated in each area. (you can use words) Discuss the events that are taking place in the cardiac cycle during the left ventricular systole. Indicate whether the other heart chambers are in systole or diastole and whether they are filling or emptying of blood. If they are emptying, state where the blood is going. If they are filling with blood, state where the blood is coming from. Include an explanation of which valves are open and which valves are closed, in addition to whether the coronary system is filling or emptying of blood.
