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 A proximal convoluted tubule drains filtrate away from a renal corpuscle. 2  A loop of Henle descends into the medulla, makes a hairpin turn, and returns to the cortex. 3  The distal convoluted tubule passes near to the original corpuscle (at the juxtaglomerular apparatus), then leads to a collecting duct.he epithelium of the initial descending segment of the loop of Henle is similar to that of the proximal convoluted tubule, and is sometimes called the pars recta of the proximal tubule (in contrast to the convoluted pars convoluta).
