describe the location structure and primary function of the proximal convoluted tubule
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.he proximal convoluted tubule (PCT) is a small tubular structure within the nephron of the kidney.
Fluid in the filtrate entering the proximal convoluted tubule is reabsorbed into the peritubular capillaries. This is driven by sodium transport from the lumen into the blood by the Na+/K+ ATPase in the basolateral membrane of the epithelial cells.Sodium reabsorption is primarily driven by this P-type ATPase.he proximal tubule as a part of the nephron can be divided into two sections, pars convoluta and pars recta. Differences in cell outlines exist between these segments, and therefore presumably in function too.
