Question

Which of the following is not a part of the nephron

• A. glomerulus
• B. alveoli
• C. bowman's capsule
• D. convoluted tubules

Answer 1

The correct option is B

alveoli

The correct option is B.

Explanation of the Correct Option:

• Alveoli is the structural part of the lungs where the exchange of oxygen, as well as carbon dioxide, occurs with blood.
• The exchange of gases with blood occurs during the process of respiration.
• Nephron facilitates blood filtration and is not involved in the exchange of gases.

Explanation of the Incorrect Options:

Option A:

• The glomerulus is the part of the kidney that filters waste from the blood.

Option C:

• Bowman's capsule is also termed a glomerular capsule. It is a cup-shaped doubled, layered structure that facilitates blood filtration from the capillaries.

Option D:

• The convoluted tubule is a structural component of the nephron. It consists of distal and proximal convoluted tubules. The distal convoluted tubule lies between the loop of Henle and the collecting tubule, while the proximal convoluted tubule lies between macula densa and the collecting duct.

Alveoli is a structural component of the lungs and is not related to nephrons.
