The filtrate on evaporation yields ammonium chloride. Fluid in the filtrate entering the proximal convoluted tubule is reabsorbed into the peritubular capillaries. Tubular secretion occurs simultaneously during reabsorption of filtrate. The filtrate then enters the renal tubule of the nephron. This hypotonic filtrate is passed to the distal convoluted tubule in the renal cortex. The solid crystals are collected by filtration and the filtrate is discarded. The glomerular filtrate leaves the Bowman's capsule at the renal tubule at the urinary pole. SGLT proteins cause the glucose reabsorption from the glomerular filtrate, independent of insulin. The filtrate passes into the renal tubules of the kidney. Pre coat filtration is an ideal method to produce a high clarity of filtrate. Aldosterone is responsible for the reabsorption of about 2% of filtered glomerular filtrate. They increase the osmolarity of blood and renal filtrate. The Bowman's capsule surrounds each glomerulus, and collects the filtrate that the glomerulus forms. The filtrate that has passed through the three-layered filtration unit enters Bowman's space. The renal filtrate it carries drains into a minor calyx as urine.
