Current Question (ID: 14626)

Question:

Vasa recta in cortical nephrons:

Options:

1. Arises from afferent arteriole rather than efferent arteriole
2. Does not get involved in counter current exchange with loop of Henle
3. Carries deoxygenated blood rich in urea
4. Is absent or highly reduced

Solution:

Vasa recta is absent or highly reduced in cortical nephrons. The vasa recta is a network of specialized capillaries that supply blood to the medulla of the kidney, where they participate in a countercurrent exchange system with the loop of Henle to help maintain the high osmotic gradient necessary for urine concentration. Cortical nephrons are located primarily in the cortex of the kidney and have a shorter loop of Henle, so they do not require as much blood flow from the vasa recta. Therefore, the vasa recta is absent or highly reduced in cortical nephrons.
