The Capillaries of the Glomerulus Differ from Other Capillary Networks

Question

The capillaries of the glomerulus differ from other capillary networks in the body because they
A)carry only deoxygenated blood.
B)drain into an arteriole instead of a venule.
C)contain no endothelium.
D)absorb nutrients from the glomerular capsule.
E)secrete mucus.

Accepted Answer

The capillaries of the glomerulus drain into an arteriole instead of a venule, which is different from most other capillary networks in the body. This unique arrangement allows for the high pressure and filtration needed for urine formation in the kidneys. The other options are incorrect: A) the capillaries of the glomerulus carry oxygenated blood, not deoxygenated blood; C) capillaries always contain endothelium; D) the glomerular capsule filters waste products rather than absorbing nutrients; E) capillaries do not secrete mucus.
