The distal convoluted tubule (DCT) is a portion of the nephron in the kidney, situated after the loop of Henle and before the collecting duct. It plays a crucial role in the regulation of electrolytes and the reabsorption of water, thus contributing to the overall balance of fluids in the body. The DCT is involved in processes like selective reabsorption and secretion, which help maintain homeostasis and adjust the composition of urine.
