Q:

What vessel carries blood into the glomerulus?

A:

Quick Answer

Blood travels into the glomerulus via the afferent arteriole, explains Dr. Dawn A. Tamarkin of Springfield Technical Community College.

Full Answer

Electrolytes, glucose, hormones, water molecules and nitrogenous waste products pass through the split pores, emptying into the glomerular capsule space as filtrate. Larger materials, such as cells and proteins, remain in the blood. The filtered blood exits the glomerulus via the efferent arteriole. Some of the filtered materials are reabsorbed by the body as the filtrate passes through the nephron loop, explains Tamarkin. Unnecessary or harmful materials, such as excessive electrolytes and waste products, exit the body as urine.
