The relatively high pressure in the glomerulus is related to the fact that the

a. afferent arteriole is part of the systemic arterial circulation.
b. efferent arteriole is larger in diameter that the afferent arteriole.
c. glomerulus has constricted capillaries.
d. afferent arteriole has a larger diameter than the efferent arteriole.

Answer:

The correct answer will be option D.

Step-by-step explanation:

The glomerulus is a small tuft like structure formed by the clusters of the small capillaries in around the end of kidney tubule.

The glomerulus plays an important role in the formation of urine as it filters the blood in the kidney. The filtration rate of glomerulus depends on the glomerulus pressure which is measured generally high due to the size difference of the arterioles that brings the blood to the kidney and that takes the blood from the kidney that is afferent arteriole and efferent arteriole.

The smaller diameter of the efferent arteriole causes the resistance to blood flow which produces the blood to be retained in the glomerulus which creates high pressure in the glomerular cavity.

Thus, option D is the correct answer.
