Final answer:
The majority of solute reabsorption in the nephron occurs in the proximal convoluted tubule (PCT). This is where ions, water, and nutrients are reabsorbed from the filtrate into the interstitial fluid. The PCT is the primary site of solute reabsorption in the nephron.
Step-by-step explanation:
The majority of solute reabsorption in the nephron occurs in the proximal convoluted tubule (PCT).
During tubular reabsorption in the PCT, ions, water, and nutrients are reabsorbed from the filtrate into the interstitial fluid. This reabsorption process helps maintain homeostasis by regulating the balance of solutes and water in the body.
While some additional solutes and wastes are also reabsorbed in the distal convoluted tubule and collecting duct, the PCT is the primary site of solute reabsorption in the nephron.
