Detailed explanation-1: -Kidneys are a special filter system for your body. Kidneys remove waste products from the blood and produce urine. Kidneys control the levels of many substances in the blood. Kidneys help to control your blood pressure.
Detailed explanation-2: -The kidneys remove waste products called urea from the blood through tiny filtering units called nephrons. There are about one million nephrons in each kidney. Each nephron consists of a ball formed of small blood capillaries, called a glomerulus, and a small tube called a renal tubule.
Detailed explanation-3: -Their main job is to cleanse the blood of toxins and transform the waste into urine. Each kidney weighs about 160 grams and gets rid of between one and one-and-a-half litres of urine per day. The two kidneys together filter 200 litres of fluid every 24 hours.
