Question

The middle part of the nephric tubule is

• A. distal convoluted tubule
• B. proximal convoluted tubule
• C. loop of Henle
• D. ducts of Bellini

Answer 1

The correct option is C

loop of Henle

The correct option is C:

Explanation of the correct option:

• The nephric tubule is also called a renal tubule. It is a long and narrow tube-like structure that retains essential nutrients and vital fluids in the blood.
• The nephric tubule is composed of several regions with distinct functions. Those portions include the proximal convoluted tubule, distal convoluted tubule, and the loop of Henle.
• Distal convoluted tubule connects via a loop of Henle to the proximal convoluted tubule.
• The loop of Henle resembles a U-shaped structure.

Explanation of the incorrect options:

Option A:

• A distal convoluted tubule is a part of the renal tubule which lies between the collecting tubule and the loop of Henle.

Option B:

• The proximal convoluted tubule is a structural part of the renal tubule which lies between the glomerulus and the loop of Henle.

Option D:

• The ducts of Bellini are called collecting tubules connected to the distal convoluted tubule and transport urine from the nephron to the kidney.

The middle part of the nephric tubule is called the loop of Henle.
