Text Solution

Verified by Experts
The correct answer is:
A

• Micturition is a reflex action controlled by the CNS, involving bladder contraction and urethral sphincter relaxation for urine release.

• ADH reduces water loss by increasing water reabsorption in collecting ducts, producing concentrated (hypertonic) urine, not hypotonic.

• The glomerular filtrate is essentially protein-free plasma ultrafiltrate.

• Loop of Henle is central to the counter-current mechanism that concentrates urine.

• Glucose is reabsorbed in the PCT by active (secondary active) transport.
