Detailed explanation-1: -The kidneys remove waste products called urea from the blood through tiny filtering units called nephrons.
Detailed explanation-2: -The process of eliminating these waste products from the body is called excretion.
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.
Detailed explanation-4: -Each of the nephrons contain a filter called the glomerulus (pronounced: gluh-MER-yuh-lus). The fluid that is filtered out from the blood then travels down a tiny tube-like structure called a tubule (pronounced: TOO-byool). The tubule adjusts the level of salts, water, and wastes that will leave the body in the urine.
