t/f: the enzyme phosphodiesterase inactivated the second messenger of the Phospholipase C-Ca++ second messenger system
false, should be CAMP not phospholipase
t/f: the most abundant type of leukocyte is the basophil
false
the reason that the secondary response of circulating antibodies is higher than the primary response is because of the presence of more plasma cells
false, should be memory cells
t/f: the tubular component of man's circulatory system with the largest total cross-sectiona area is the veins
false, should be arteries
t/f: the hormone system which is activated when a person hemorrhages and loses a substantial volume of blood is the renin-angiotensin system
true
t/f: it is possible for man to increase the amount of oxygen t/f: arriving at the ecells of his body during exercise by about 5-6 times the resting amount as a result of a combination of adaptations of the respiratory cardiovascular systems.
false, should be 15-18
t/f: most of the carbon dioxide which is trasported by the blood stream is in the form of CO2 ions
false, should be HO3
t/f: the osmolality of urine is controlled by the circulating concentration of aldosterone
false, should be ADH
t/f: the enzyme which converts fibrinogen to the fibrin threads of the blood clot is prothrombin activator
false, should be thrombin
t/f: in addition to NaCl, the other osmolyte present in the inner medullary interstitial fluid compartment is ADH
false, should be urea
t/f: clinical symptoms of glucose in the urine and the presence of autoantibodies against the Beta cells of the Islets of Langerhans would lead to a diagnosis of the form of Diabetes mellitus known as adult onset
false, should be juvenile
t/f: the T wave component of an EKG trace is due to K+ efflux from the atria
true
t/f: podocytes are associated witht he glomerular capsule
true
t.f: the hormone responsible for stiulating testosterone production in man is PSH
false, should be L H

20-33
the end product of purine catabolism in man is
uric acid
the type of leukoocyte that releases heparin into the blood is a
