Skeletal muscle make up the:
1. external urethra sphincter
2. internal urethra sphincter
3. renal capsule
4. ureter walls

In the male, urethra serves to:
1. transport urine from kidney to bladder
2. transport sperms to ejaculatory ducts
3. store urine and sperms
4. discharge semen and urine

If the cardiac output is about 6L/min, the renal blood flow/min would be about:
1. 180 L
2. 1200 ml
3. 500 ml
4. 700 ml

The reabsorption of chloride ions in the renal tubules if determined by:
1. rate of potassium reabsorption
2. rate of sodium reabsorption
3. rate of potassium secretion
4. rate of phosphate reabsorption

The net filtration pressure in human kidney is estimated to be:
1. 60 mm Hg
2. 32 mm Hg
3. 18 mm Hg
4. 10 mm Hg

The presence of which of the following in urine would be abnormal?

The major site for the reabsorption of bicarbonate ions in the nephron is the:

Angiotensinogen in blood is secreted by:

Glycosuria is seen in diabetes mellitus mainly because:
1. the length of PCT is shorter in diabetics.
2. sodium plus glucose symports in the distal tubules are defective.
3. sodium plus glucose symports in the proximal convoluted tubule are defective.
4. transport maximum for glucose reabsorption in the proximal tubule is exceeded.

A substance like inulin is readily filtered at the glomerulus but is not reabsorbed or secreted in the tubules. The renal clearance rate of inulin:

1. equals the GFR.

2. is always greater than the GFR.

3. is less than the GFR.

4. does not affect the GFR.
