Verified step by step guidance

Understand the function of the nephron: 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 role in the filtration and reabsorption process.

Identify the role of the glomerulus: The glomerulus is a network of capillaries located within the Bowman's capsule. Its primary function is to filter blood, allowing water, ions, and small molecules to pass into the nephron while retaining larger molecules like proteins and blood cells.

Compare the roles of other nephron structures: The Loop of Henle is involved in concentrating urine by reabsorbing water and salts. The distal convoluted tubule fine-tunes the reabsorption of ions and water, while the collecting duct is responsible for the final adjustments to urine composition and water reabsorption.

Focus on filtration: Filtration specifically occurs in the glomerulus due to the high pressure in the capillaries and the selective permeability of the glomerular membrane.

Conclude that the glomerulus is the structure primarily responsible for blood filtration in the nephron, as it initiates the process of separating waste products and excess substances from the blood.
