AIIMS 2019 Biology Structure of Nephron MCQ Question

Bowman's capsule and the glomerulus are integral components of the nephron in the kidney, primarily responsible for the filtration of blood, not the reabsorption of hormones. They work together to filter plasma, allowing water (H₂O), ions, and small molecules to pass into the renal tubule while retaining larger molecules and cells in the bloodstream. Options B, C, and D pertain to reabsorption processes that occur later in the nephron, specifically in the proximal convoluted tubule and loop of Henle, rather than in Bowman's capsule and the glomerulus. Thus, the primary function of these structures is accurately described by option A, which highlights their role in blood filtration.
