Explanation: 

Detailed explanation-1: -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.

Detailed explanation-2: -The kidney and urinary systems help the body to get rid of liquid waste called urea. They also help to keep chemicals (such as potassium and sodium) and water in balance. Urea is made when foods containing protein (such as meat, poultry, and certain vegetables) are broken down in the body.
