Chapter 7, Problem 23MC

Which of the following does not contribute to the process of filtration? (a) active transport by epithelial cells lining renal tubules (b) large surface area for filtration (c) low permeability of glomerular capillaries (d) high hydrostatic blood pressure in glomerular capillaries (e) podocytes

Which of the following correctly describes a part of kidney function? a. Collecting ducts dilute urine because they are permeable tosalt but not water. b. In the ascending loop of Henle, Na1 and Cl2 move into thetubules because the osmolarity of the filtrate is increased. c. The descending loop of Henle receives filtrate from theascending loop. d. The distal convoluted tubule pumps water into the tubule byactive transport. e. The renal pelvis receives urine from the collecting ducts andcarries it to the ureters.

Figure 41.5 Which of the following statements about the kidney is false? The renal pelvis drains into the ureter. The renal pyramids are in the medulla. The cortex covers the capsule. Nephrons are in the renal cortex.
