What is the primary role of renal corpuscles in the kidneys?

• A. To secretion of hormones
• B. To filter blood
• C. To absorb nutrients
• D. To transport urine

Answer: (B)

Renal corpuscles play a crucial role in the kidney's function of filtering blood. Each renal corpuscle comprises a glomerulus and Bowman's capsule. The glomerulus is a network of capillaries where blood is filtered under pressure. This filtration process allows water, ions, and small molecules to pass through while retaining larger molecules like proteins and blood cells within the bloodstream. The filtrate collected in Bowman's capsule then enters the renal tubules, where further processing occurs, contributing to the formation of urine. Thus, the primary function of renal corpuscles is to filter blood, initiating the process of urine formation by removing waste products and excess substances from the bloodstream.
