The part of the nephron where both hydrogen and potassium ions are secreted into the tubular fluid is the

1. Malpighian body	2. proximal convoluted tubule
3. loop of Henle	4. distal convoluted tubule

The flow rate of filtered fluid through the kidney is:
1. glomerular filtration rate.
2. renal plasma flow.
3. filtration fraction.
4. renal blood flow.

Given that the hydrostatic pressure at the glomerulus is 50 mm Hg, the blood colloid osmotic pressure is 30 mm Hg and the capsule pressure is 20 mm Hg, the net filtration pressure would be:

1. (--) 20 mm Hg.

2. 0 mm Hg.

3. 20 mm Hg.

4. 60 mm Hg.

5. 80 mm Hg.

The GFR will be decreased if there is:
1. elevated blood pressure
2. constriction of the afferent arterioles
3. decreased blood colloid osmotic pressure
4. decreased capsule pressure

Identify the point in the nephron by which glucose is completely reabsorbed from the filtrate under normal physiological conditions:
1. the end of the proximal tubule.
2. the tip of the loop of Henle.
3. the end of the distal tubule.
4. the end of the collecting duct.

Specialized smooth muscle cells mainly in the walls of the afferent arterioles called the Juxtaglomerular cells secrete:

The blood flow to which of the following will be directly caused by a blockage in a glomerulus?

1. afferent arteriole

2. efferent arteriole

3. renal artery

4. arcuate artery

The hormone produced by the adrenal cortex, when stimulated by angiotensin II, that causes increased sodium and water reabsorption in the distal convoluted tubules, is:

A deficiency of antidiuretic hormone (vasopressin) is most likely to result in:

1. dehydration

2. incontinence

3. anuria

4. cystitis

Which of the following statements is correct?
1. The ascending limb of the loop of Henle is impermeable to water
2. The descending limb of the loop of Henle is impermeable to water
3. The ascending limb of the loop of Henle is permeable to water
4. The descending limb of the loop of Henle is permeable to electrolytes
