Which part of the nephron filters blood in the renal corpuscle?

Bowman’s capsule Renal pelvis Glomerulus Ureter

Correct Answer:

Glomerulus

Explanation:

Filtration in the renal corpuscle is carried out by the glomerulus, a tuft of capillaries whose walls form the first filtration barrier. Blood entering through the afferent arteriole is under pressure, and water, ions, and small solutes pass through the fenestrated endothelium, the basement membrane, and the podocyte slit diaphragms. This creates the filtrate that enters Bowman's capsule. Bowman's capsule simply collects this filtrate and funnels it into the renal tubule for processing. The renal pelvis and ureter are parts of the urinary tract that transport urine to the bladder, not involved in filtration.
