WebbAfter leaving the proximal convoluted tubule, the tubular fluid enters the proximal straight tubule, where around 15% of the phosphate is reabsorbed. Diagram showing how ions and other substances are … The proximal tubule is the segment of the nephron in kidneys which begins from the renal pole of the Bowman's capsule to the beginning of loop of Henle. It can be further classified into the proximal convoluted tubule (PCT) and the proximal straight tubule (PST). Visa mer The most distinctive characteristic of the proximal tubule is its luminal brush border.
