gradient d. temperature gradient 35. Plasma contains a much greater concentration of than the
glomerular filtrate. a. urea b. water c. protein d. sodium ions 36. Most water is reabsorbed from
the filtrate in the a. proximal convoluted tubule b. descending loop of Henle c. ascending loop of
Henle d. distal convoluted tubule 37. If the following hypothetical conditions exist in the
nephron, calculate the net filtration pressure. glomerular capillary pressure-80mmHg blood
colloid osmotic pressure 20mmHg capsular colloid pressure-10mmHg a. 110mmHg b. 90mmHg
c. 50mmHg d. 30mmHg 38.The collecting duct becomes more permeable to water when a.
colloid osmotic pressure increases b. ADH production increases c. plasma osmolarity decreases
d. aldosterone production decreases by the process of active transport. 39. Potassium ion enters
the lumen of the a. proximal tubule b. renal corpuscle c. loop of Henle d. distal tubule
Solution
34) a Pressure gradient
35) c Protein
36) a Proximal convaluted tubule
37) c 50 mmHg [80 mmHg- (20 mmHg + 10 mmHg)]
38) b ADH production increases
39) d Distal tubule
