Which of the following structures is responsible for filtering blood within the renal corpuscle?

Identify the role of the glomerulus: The glomerulus is a network of capillaries within the renal corpuscle. It is responsible for filtering blood by allowing water, ions, and small molecules to pass through its walls while retaining larger molecules like proteins and blood cells.

Differentiate the other options: The collecting duct is involved in the final concentration of urine, the proximal convoluted tubule reabsorbs nutrients and water, and the loop of Henle is responsible for creating a concentration gradient in the medulla. None of these structures are directly involved in blood filtration within the renal corpuscle.
