Verified step by step guidance

Understand the anatomy of the nephron: The nephron is the functional unit of the kidney, consisting of the glomerulus, Bowman's capsule, proximal tubule, loop of Henle, distal tubule, and collecting duct.

Identify the role of the peritubular capillaries: These are tiny blood vessels that surround the proximal and distal tubules of the nephron, playing a crucial role in the reabsorption and secretion processes.

Differentiate between the structures: The glomerulus is a network of capillaries involved in the filtration of blood, while Bowman's capsule encases the glomerulus. The loop of Henle is a U-shaped structure involved in concentrating urine.

Focus on the location of the peritubular capillaries: These capillaries are specifically associated with the proximal and distal tubules, facilitating the exchange of substances between the blood and the tubular fluid.

Conclude that the peritubular capillaries are the structures that surround the proximal and distal tubules, aiding in the nephron's function of filtering and modifying the filtrate to form urine.
