Blood Pressure Drives Filtration in the ____

Question

Blood pressure drives filtration in the ____.  
A) urethra
B) renal artery
C) glomerulus
D) plasma
E) sodium-potassium pumps

Accepted Answer

Filtration in the kidneys occurs in the glomerulus, a network of capillaries. Blood pressure drives the filtration process as blood is forced through the capillaries, and small molecules like water, salts, and waste products are filtered out and directed toward the renal tubules. Therefore, blood pressure drives filtration in the glomerulus.
