Question

The factor(s) responsible for ultrafiltration is/are:

पर्याय

• Difference in the width of afferent and efferent arteriole

• Generation of the hydrostatic pressure

• Ureteral peristalsis

• Both the difference in the width of afferent and efferent arterioles and the generation of hydrostatic pressure.

Answer 1

Both the difference in the width of afferent and efferent arterioles and the generation of hydrostatic pressure.

Explanation:

The afferent arteriole is wider than the efferent arteriole, producing high hydrostatic pressure in the glomerulus. This pressure forces the fluid part of blood into Bowman's capsule. Ureteral peristalsis is related to the movement of urine, not ultrafiltration.
