Question

Quizplus · Accepted Answer

Sodium reabsorption primarily occurs in the proximal tubule, where around 65% of filtered sodium is reabsorbed along with glucose, amino acids, H₂O, and other solutes. Answer: A Sodium reabsorption continues in the distal and collecting tubules, but to a lesser extent than in the proximal tubule. In these segments, sodium reabsorption is more regulated by aldosterone and plays a key role in potassium secretion. Answer: C Sodium reabsorption is coupled with chloride reabsorption in the loop of Henle, which helps to establish the concentration gradient necessary for water reabsorption. The thick ascending limb actively transports sodium and chloride out of the tubular fluid, while the thin descending limb allows water to passively diffuse out.
