Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The portion of the nephron that empties into the collecting duct is the
A
nephron loop (loop of Henle).
B
proximal convoluted tubule.
C
distal convoluted tubule.
D
papillary tubule.
Explanation: 

Detailed explanation-1: -The distal convoluted tubule is the portion of the nephron that empties into the collecting duct.

Detailed explanation-2: -The collecting duct empties into the distal convoluted tubule. The Bowman’s capsule surrounds the glomerulus. The loop of Henle is between the proximal and distal convoluted tubules. The loop of Henle empties into the distal convoluted tubule.

Detailed explanation-3: -The distal convoluted tubule is the nephron segment that lies immediately downstream of the macula densa. Although short in length, the distal convoluted tubule plays a critical role in sodium, potassium, and divalent cation homeostasis.

Detailed explanation-4: -It then coils again to form another region called the distal convoluted tubule. The distal tubule empties urine into the collecting duct.
