Verified step by step guidance

Understand the function of the kidney: The kidney's primary role is to filter blood, remove waste products, and regulate water and electrolyte balance. This process begins in specialized structures within the kidney.

Identify the renal corpuscle: The renal corpuscle is the structure responsible for filtering blood. It consists of two main components: the glomerulus (a network of capillaries) and Bowman's capsule (a surrounding structure that collects the filtrate).

Clarify the role of the glomerulus: Blood enters the glomerulus through the afferent arteriole, where filtration occurs due to pressure differences. Waste products, water, and small molecules pass through the glomerular membrane into Bowman's capsule, forming the initial filtrate.

Differentiate the renal corpuscle from other kidney structures: The renal pyramid, ureter, and renal pelvis are involved in urine transport and storage, but they do not filter blood. The renal corpuscle is the only structure responsible for filtration.

Conclude the answer: Based on the explanation, the correct structure responsible for filtering blood to form urine is the renal corpuscle.
