Antidiuretic hormone (ADH) controls the concentration of urine by manipulating the permeability of the collecting ducts.

1.

Alcohol consumption generally leads to greater urine volume. How does alcohol affect urine concentration in the body?

Alcohol inhibits ADH, which results in the movement of ions from the collecting duct into the renal medulla.

Alcohol inhibits ADH, and prevents water from leaving the collecting duct and entering the renal medulla.

Alcohol inhibits ADH, and causes water to diffuse into the renal medulla from the collecting duct.

Alcohol stimulates ADH, which causes an increase in renin secretion

Alcohol stimulates ADH and causes the urine to become very concentrated.
