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.
1 Approximately 65% of the filtered salt and water is reabsorbed across the proximal convoluted tubules. 2  Sodium is actively transported, chloride follows passively by electrical attraction, and water follows the salt out of the proximal tubule. 3  Salt transport in the proximal tubules is not under hormonal regulation.
