Question

20. In the nephrons of amphibians, glucose in the proximal convoluted tubule returns to the blood by a. simple diffusion b. facilitated diffusion. c. primary active transport. d. secondary active transport. Blood Capsular fluid Blood pressare in glomenular capllary loid osmotic pressure Capsular fluid hydrostatic pressure Filtration pressure (net force favoring filtration) 21. Based on the information shown, if the blood pressure in the glomerular capillary is +5 kPa, the colloid osmotic pressure is -2.5 kPa, and the capsular fluid hydrostatic pressure is -2 kPa, then the filtration pressure is kPa. a. 0.5 b. 4.5 c. 5.0 d. 5.5 22. In mammals that have similar sized kidneys, the length of the loop of Henle in nephrons is correlated with the a. number of nephrons b. thickness of the renal medulla. C. presence of a renal pelvis. d. length of the kidney cortex

Explanation / Answer

20) Option B- Facilitated diffusion

22) Option B- Thickness of the renal medulla.
