Verified step by step guidance

Understand the nephron's role in the kidney: The nephron is the functional unit of the kidney responsible for filtering blood and forming urine. It consists of several structures, each with a specific function.

Identify the process of filtration: Filtration is the first step in urine formation, where blood plasma is filtered to remove waste products, excess ions, and water. This occurs in a specialized structure within the nephron.

Focus on the glomerulus: The glomerulus is a network of capillaries located within the Bowman's capsule. It is the primary site of filtration, where blood pressure forces water and solutes out of the blood and into the nephron.

Differentiate the glomerulus from other nephron structures: The Loop of Henle, distal convoluted tubule, and collecting duct are involved in reabsorption, secretion, and concentration of urine, but they do not perform filtration. Filtration is exclusive to the glomerulus.

Conclude that the glomerulus is the correct answer: Based on its function and location within the nephron, the glomerulus is the structure primarily responsible for filtration of blood.
