GENERAL HISTOLOGY

Detailed explanation-1: -Each of your kidneys is made up of about a million filtering units called nephrons. Each nephron includes a filter, called the glomerulus, and a tubule. The nephrons work through a two-step process: the glomerulus filters your blood, and the tubule returns needed substances to your blood and removes wastes.

Detailed explanation-2: -The nephron is the filtering unit of the kidney. The nephron is called so because it removes harmful wastes from the blood, such as urea, uric acids, and excess of water. These wastes get filtered from the blood and excreted out as urine and useful products are reabsorbed by the tubular part of the nephron.
