Question

Blood enters the glomerulus through its ___________ arteriole and leaves the glomerulus through its __________ arteriole.

• A. Afferent
• B. Efferent

Answer 1

Glomerulus:

1. It is the bundle of the capillary network present in the cup-shaped cavity of Bowman's capsule.

Afferent arteriole:

1. It brings in blood containing nitrogenous wastes to the glomerulus.
2. It contains blood with high pressure.
3. It is wider than the efferent arteriole.

Efferent arteriole:

1. It drains blood (lack of nitrogenous wastes) away from the glomerulus.
2. The pressure of the blood in the efferent arteriole is less than that of the afferent arteriole.
3. It is narrower than afferent arterioles.

Final answer: Blood enters the glomerulus through its afferent arteriole and leaves the glomerulus through its efferent arteriole.
