Question

Which of the following blood vessels gives rise to the peritubular capillaries?

afferent arteriole

glomerulus

efferent arteriole

vasa recta

Part B

About 85 percent of all nephrons __________.

are juxtamedullary nephrons

have vasa recta surrounding the nephron loops

are located entirely within the medulla

are cortical nephrons with short nephron loops

Part C

Filtrate produced in the renal corpuscle flows directly into the __________.

nephron loop (loop of Henle)

collecting duct

proximal convoluted tubule

renal pelvis

Answer 1

1. Option 3rd is the correct answer.

There are two types arterioles: Afferent arterioles supplies blood to the renal corpuscles and efferent arteioles which carries blood away from the glomerulus and extended to form peritubular capillaries.

2. Option last is the correct answer.

There are two types of nephrons: cortical nephrons (85%) which lie deep in the renal cortex and juxtamedullary nephrons (15%) which lie in the renal cortex close to the renal medulla.

3. Option 3rd is the correct answer.

Renal corpuscles is composed of glomerulus and glomerular capsule. The filtrate from renal corpuscles directly move to the proximal convulated tubule.
