The proximal convoluted tubule (PCT) is a small tubular structure within the nephron of the kidney. The PCT connects Bowman's capsule with the proximal straight tubule, and it is essential for the reabsorption of water and solutes from filtrate within the nephron.
Late distal convoluted tubule and collecting duct (distal nephron). The distal nephron is the site of two important processes: (1) involves exchange of sodium for potassium and is under the influence of aldosterone. (2) determines the final concentration of the urine and is regulated by ADH.
