Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What blood vessel surrounds the nephron tubule and allows for the exchange of substances between the filtrate of the tubule and the blood of the circulatory system?
A
Peritubular capillaries
B
Efferent arteriole
C
Afferent arteriole
D
Renal artery
Explanation: 

Detailed explanation-1: -Peritubular capillaries are tiny blood vessels in your kidneys. They filter waste from your blood so the waste can leave your body through urine (pee). Peritubular capillaries also reabsorb nutrients your body needs to work properly, such as minerals.

Detailed explanation-2: -Peritubular capillaries: Peritubular capillaries are tiny blood vessels, supplied by the efferent arteriole, that travel alongside nephrons and surrounds them allowing reabsorption and secretion between blood and the inner lumen of the nephron.

Detailed explanation-3: -The blood vessels wrapped around the loop of Henle deep in the medulla are called the vasa recta. The vasa recta acts as a countercurrent exchanger to concentrate the filtrate.

Detailed explanation-4: -Efferent arteriole. This vessel carries blood from the glomerulus to the peritubular capillaries or the vasa recta.
