Major site of tubular secretion

Web1 dag geleden · As discussed above in the remote sensing and signaling theory, tubular secretion occurs via an evolutionary highly conserved machinery of transporter proteins that can handle organic anions and cations ( Figure 1 ). They may be located on the basolateral or luminal side of tubular epithelial cells and participate in secretion or reabsorption. WebTubular secretion occurs mostly in the PCT and DCT where unfiltered substances are moved from the peritubular capillary into the lumen of the tubule. Secretion usually removes substances from the blood that are too large to be filtered (ex: antibiotics, toxins) or those that are in excess in the blood (ex: H +, K + ).
