Basically, a nephron comprises a renal tubule and blood vessels. The renal tubule expands into a cup-shaped structure called the Bowman's Capsule, which contains a ball of capillaries known as the Glomerulus. The Glomerulus is the primary structure of the filtering process.
Each segment of the tubule reabsorbs different substances from the filtrate as it passes through them. A second network of capillaries separate from the glomerulus, the peritubular capillaries, entwines the renal tubule to allow the reabsorbed materials to reenter the blood circulation.ifferent portions of the loop of Henle reabsorb sodium, potassium, chloride, magnesium, calcium, and water. The loop of Henle plays a significant role in the concentration and dilution of the URINE, and is the target of some types of diuretic medications.
