The selective re-absorption of glomerular filtrate takes place in the distal convolute tubule (DCT) .It is a portion of the functional unit of kidney called nephron which lies between the loop of Henle and the collecting tubule. Once the filtrate passes through the ascending limb of Henle, it then enters the distal convoluted tubule (duct of the renal tubule present in the cortex of kidney) that selectively reabsorbs minerals like calcium, sodium, and chloride thus regulating the pH of urine by secreting H+ ions and absorbing bicarbonate ions.
