NEET PG DENTAL EXAM

Detailed explanation-1: -The distal convoluted tubule and collecting duct is the final site of reabsorption in the nephron. Unlike the other components of the nephron, its permeability to water is variable depending on a hormone stimulus to enable the complex regulation of blood osmolarity, volume, pressure, and pH.

Detailed explanation-2: -Approximately 7%–10% of filtered calcium is reabsorbed in the DCT. In contrast to other segments of the nephron, which passively reabsorb calcium through paracellular routes, 100% of the calcium that is reabsorbed in the DCT occurs by active transcellular mechanisms.

Detailed explanation-3: -The distal convoluted tubule (DCT) and collecting duct (CD) are the final two segments of the kidney nephron. They have an important role in the absorption of many ions, and in water reabsorption. The distal convoluted tubule can be subdivided into the early and late sections, each with their own functions.
