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.
These substances are water, glucose, amino acids, vitamins, bicarbonate ions, and the chloride salts of calcium, magnesium, sodium and potassium. Reabsorption starts in the proximal tubules and continues through the Henle's loop, to the distal tubule and then to the collecting tubules.bout 99% of the initial filtrate from the glomerulus is reabsorbed by the nephron and returned to the blood in the peritubular capillaries. o The number of nephrons does not increase after birth. Growth of the kidney is due to the enlargement of existing nephrons not due to an increase in their number.
