Filtration occurs because
A)the glomerulus is leaky.
B)the afferent arteriole is wider in diameter than the efferent arteriole.
C)the capillary wall is not completely ensheathed by the visceral layer of the glomerular capsule.
D)the filtration slits allow materials from the blood plasma to enter the capsular space.
E)All of the choices are correct.

Question

Quizplus · Accepted Answer

All of the choices listed are correct and contribute to the occurrence of filtration in the renal corpuscle. The glomerulus is leaky due to its fenestrated capillaries, the afferent arteriole is wider in diameter than the efferent arteriole creating high blood pressure within the glomerulus, the capillary wall is not completely ensheathed by the visceral layer of the glomerular capsule allowing for space through which filtrate can pass, and the filtration slits allow materials from the blood plasma to enter the capsular space.
