adh has the greatest effect on the reabsorption of water in the:
proximal tubule.
ascending nephron loop.
descending nephron loop.
distal tubule.
question 138
0.25 pts
reabsorption, as performed in the kidney, may be defined as the:
movement of molecules out of the tubule and into the peritubular blood.
movement of molecules out of the peritubular blood and into the tubule for excretion.
movement of water and solutes from the plasma in the glomerulus, across the glomerular-capsular membrane, and into the capsular space of the glomerular capsule.
volume of plasma from which a substance is removed by the kidney per minute.

Explanation:

Question 136

This question is about the proportion of blood pumped by the heart that goes to the kidneys, which is a topic in Medicine and Health (a subfield of Natural Science). The correct proportion is approximately 1/5 (20%) of the cardiac output that perfuses the kidneys.

This question is about the effect of ADH (Antidiuretic Hormone) on water reabsorption in the nephron, which is a topic in Medicine and Health (a subfield of Natural Science). ADH primarily acts on the distal tubule (and collecting duct, though distal tubule is the closest option here) to increase water reabsorption.

This question is about the definition of reabsorption in the kidney, which is a topic in Medicine and Health (a subfield of Natural Science). Reabsorption is the movement of molecules (like nutrients, ions, water) out of the renal tubule and back into the peritubular blood to be retained in the body.
