Detailed explanation-1: -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-2: -One of millions of tiny tubes in the kidneys that returns nutrients, fluids, and other substances that have been filtered from the blood, but the body needs, back to the blood. The remaining fluid and waste in the renal tubules become urine.
Detailed explanation-3: -The bean-shaped kidneys filter waste products out of the bloodstream and dispose of them by creating urine. Urine is made of these waste products dissolved in water.
