Where does excretion occurs in the nephron of a kidney?

Excretion in the nephron occurs primarily in the distal convoluted tubule and the collecting duct. Here, waste products, excess ions, and water are secreted from the blood into the tubular fluid. This process helps to regulate the composition of body fluids and remove unwanted substances from the body. Overall, the nephron plays a crucial role in maintaining homeostasis through filtration, reabsorption, and excretion.
