Question

As compared to efferent arteriole, the afferent arteriole of kidney is

• A. Shorter and wider
• B. Longer and wider
• C. Shorter and narrower
• D. Longer and narrower

Answer 1

The correct option is A Shorter and wider

Renal arterioles

The glomerular structure of the nephron receives blood from the afferent arteriole. The afferent arteriole carries blood with nitrogenous wastes into the glomerulus. The efferent arteriole carries the filtered blood.

The afferent arteriole is comparatively wider than that of the efferent arteriole. The afferent arteriole is shorter as well than the efferent one.

Final answer: (A) Shorter and wider
