Question

3 multiple choice 2 points the majority of ions are reabsorbed into the blood from the: descending loop of henle. proximal convoluted tubule. collecting duct. distal convoluted tubule.

Explanation:

The proximal convoluted tubule is the site where the majority of ions (such as sodium, chloride, bicarbonate, etc.) are reabsorbed into the blood in the nephron of the kidney. It has a high - capacity for reabsorption due to its brush - border epithelium which increases the surface area for transport processes.

Answer:

B. proximal convoluted tubule
