Verified step by step guidance

Understand the anatomy of the nephron: The nephron is the functional unit of the kidney, responsible for filtering blood and forming urine. It consists of structures such as the glomerulus, proximal convoluted tubule, loop of Henle, distal convoluted tubule, and collecting duct.

Identify the role of the proximal convoluted tubule: This segment of the nephron is primarily responsible for reabsorbing water, ions, and nutrients from the filtrate back into the bloodstream.

Learn about the peritubular capillaries: These capillaries surround the proximal convoluted tubule and other parts of the nephron. They are specialized for reabsorbing fluid and solutes that have been filtered out of the blood in the glomerulus.

Differentiate between the listed capillaries: Glomerular capillaries are involved in filtration, not reabsorption. Pulmonary capillaries are part of the lungs and unrelated to kidney function. The vasa recta are specialized capillaries associated with the loop of Henle, primarily involved in maintaining the concentration gradient in the medulla.

Conclude that the peritubular capillaries are responsible for picking up fluid and solutes reabsorbed in the proximal convoluted tubule, as they are anatomically and functionally suited for this task.
