Detailed explanation-1: -The kidneys remove urea from the blood through tiny filtering units called nephrons.

Detailed explanation-2: -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-3: -Your kidneys filter your blood, separating toxins from nutrients. Vitamins, minerals, nutrients and proteins return to your bloodstream. Waste products and urine move through your ureters to your bladder. Your bladder stores urine until you use the toilet.

Detailed explanation-4: -The excretory system assists with blood pressure control. In addition to preserving the body’s fluid balance, the urinary system regulates the generation of red blood cells by releasing the hormone erythropoietin. By secreting the enzyme renin, the urinary system also helps to maintain appropriate blood pressure.
