Question

In amphibians, sodium reabsorption begins in

a. the loop of Henle.
b. the proximal convoluted tubule.
c. Bowman's capsule.
d. the distal convoluted to tubule.

Answer 1

In amphibians, sodium reabsorption begins in the proximal convoluted tubule. The proximal convoluted tubule is located in the renal cortex of the kidney and is responsible for the initial filtration and reabsorption of substances from the glomerular filtrate.

Step-by-step explanation:

In amphibians, sodium reabsorption begins in the proximal convoluted tubule.

It is in this part of the nephron that most of the reabsorption of sodium occurs.

The proximal convoluted tubule is located in the renal cortex of the kidney and is responsible for the initial filtration and reabsorption of substances from the glomerular filtrate.
