Question

1.Which of the following is a primary function of the distal convoluted tubule?

d.active secretion of ions, acids, drugs, and toxins

2.The primary function of the proximal convoluted tubule is

e.actively pumping sodium ions and chloride ions out of the filtrate.

3.Filtration is the process in which

4.When the level of ADH (antidiuretic hormone) increases,

5.By inhibiting ADH secretion, alcohol essentially causes

d.metabolic acidosis.

6.he kidneys can compensate for a drop in blood pH by

d.reabsorbing both H+ and HCO3–.

7.A reduction in blood flow and a decline in glomerular filtration pressure trigger which of the following?

d. constriction of the glomerular capillaries and efferent arteriole

Select all of the following structures would be found in the cortex of the kidney:_____

Explanation / Answer

Answer 1. Option d

Distal convulated tubule occurs just after the Loop of Henle's. It is basically concerned with secretion than reabsorption.

Answer 2. Option b

Proximal Convulated Tubule occurs just after the renal capsule in the nephron and it plays more role in reabsorption than the secretion.

Answer 3. Option a

Kidneys possess the functional units, nephrons. Their Bowman's capsule are meant for it.

Answer 4. Option a

ADH or vasopressin is basically responsible for conserving water in the body. More vasopressin means more absorption of water means more water retained by the body.

Answer 5. Option a

Alcohol suppresses the vasopressin, thus no absorption of water, no conservation of water by nephron means more diluted urine will be passed, diuresis occurs.
