A) hemaglutination B) erythroblastosis C) erythrocytosis D) hemostasis E) erythropoiesis Which is characteristic of a person chronically suffering from hypoxic hypoxia? A) higher-than-normal hematocrit B) lower-than-normal blood flow through tissues C) higher-than-normal alveolar P_O2 D) lower-than-normal lactic acid production E) higher-than-normal arterial P_o2 Which of the following is NOT primarily a function of blood plasma? A) transport of oxygen B) having plasma proteins that exert an osmotic pressure favoring fluid absorption into the capillaries C) providing cloning factors that are ready to be activated D) transport of hormones E) being in osmotic balance with red blood cellsExplanation / Answer
36.C
Co2 and H20 combine in the presence of enzyme corbonic anhydrate to produce corbonic acid.
37. B
38. A
High altitude above 10000 feet is example of hypoxic hypoxia. This cause lungs deprived of oxygen.
39. E
Erythropoiesis is a process to produce Erythropoitin.
