The collecting duct is a crucial component of the nephron in the kidneys, responsible for the final concentration of urine. It plays an essential role in regulating water balance and electrolyte levels by reabsorbing water and solutes under the influence of hormones such as antidiuretic hormone (ADH). By adjusting the permeability of its walls, the collecting duct significantly impacts the volume and concentration of urine produced.
