Detailed explanation-1: -The kidneys remove from the blood the nitrogenous wastes such as urea, as well as salts and excess water, and excrete them in the form of urine. This is done with the help of millions of nephrons present in the kidney.

Detailed explanation-2: -This is the job of the excretory system. You remove waste as a gas (carbon dioxide), as a liquid (urine and sweat), and as a solid. Excretion is the process of removing wastes and excess water from the body.

Detailed explanation-3: -Your kidneys remove wastes and extra fluid from your body. Your kidneys also remove acid that is produced by the cells of your body and maintain a healthy balance of water, salts, and minerals-such as sodium, calcium, phosphorus, and potassium-in your blood.

Detailed explanation-4: -The excretory system only includes the organs that are exclusively needed for excretion. Kidneys, green glands, Malpighian tubules, nephridia, and protonephridia are examples of animal excretory organs.

Detailed explanation-5: -The kidneys remove waste products called urea from the blood through tiny filtering units called nephrons.
