Question

The macula densa cells are chemoreceptors that respond to changes in the urea content of the filtrate.

a. True
b. False

Answer 1

False.

Step-by-step explanation:

Macula densa cells are present in the lining of the distal tubule. The cells are the thicker at the site where glomerulus and distal convoluted tubule touches each other.

Macula densa can sense the change in the concentration of sodium chloride ions in the distal convoluted tubule. The mcula densa cells cannot respond to the change in urea content of filtrate.

Thus, the answer is false.
