Answer 1

HEY DEAR...!!

THE KIDNEY : Wastes in the blood come from tissue breakdown, and from food. After the body takes and uses what it needs, it sends the wastes to the kidneys. The kidneys are bean-shaped organs, about the size of a fist.  Having atleast one kidney is mandatory for living, unless treated immidietally. Because of the enormous amounts of blood passing through the kidney, kidneys sxtract 180 liters of fluid daily.
THE URINERY BLADDER : After the kidneys filter the fluid, the remaining wastes go to your bladder. The organ stores the urine, and keeps storing it until you can feel it. When you can feel it, it means that the bladder has become full, and you must urinate to release the wastes from your body.
THE SKIN : Your skin has a very important part in the excretory system. It holds moisture into every part of your body. In the excretory system, the skins job is to regulate one's body temperature. 
THE LIVER : When we eat fatty foods, the liver orders the gall bladder to release bile into the intestines. The bile then puts the waste products into the intestines. Then the intestines absorb the fats into the blood stream. 
THE LUNGS : The lungs play a mandatory role in the excretory system. Your lungs remove the carbon dioxide built up in your blood using specialized cells known as alveoli. Your lungs process the molecules into gas and when you breathe, the gas is ejected from your body.
