Current Question (ID: 14631)

Question:

Which section of the nephron follows the ascending limb of the loop of Henle?

Options:

1. descending limb of the loop
2. proximal convoluted tubule
3. distal convoluted tubule
4. collecting duct

Solution:

After the ascending limb of the loop of Henle, the tubular fluid enters the distal convoluted tubule (DCT) of the nephron. The DCT is located in the renal cortex and is responsible for further reabsorption of sodium, chloride, and calcium ions. It is also responsible for the secretion of potassium and hydrogen ions into the tubular fluid. After the DCT, the tubular fluid flows into the collecting ducts, which are responsible for the final adjustment of the urine volume and concentration. The collecting ducts merge together to form larger papillary ducts, which drain into the renal pelvis and ultimately into the ureter.
