Type A Multiple Choice: ONE out of the five possible choices is correct.
1. Considering that the net filtration pressure over the capillary wall changes from 10 mmHg out to 10
mmHg in from the arteriolar to the venous side, roughly what percentage of fluid returns to the blood
stream by the lymphatic vessels?
2. Erythropoiesis is the production of:

b) Into, out of
c) Out of, out of
d) Out of, into
e) The pressures are always at equilibrium
4. Two solutions of equal volume are separated by a membrane which is permeable to small ions and
water. Solution A contains roughly 10 g of albumin, and solution B contains 10 g of fibrinogen. Over
time, which solution will accumulate a larger volume of water due to osmotic pressure?
a) Solution B.
b) Neither, the net osmotic pressure is 0.
c) Solution A.
d) Neither, osmosis is prevented over this membrane.
e) Neither, osmotic pressure is only rel
