Talk:Excretory system

My name is Alfread and i'm a young mature young man and I learned about the excretory system. As well as I know that the SKIN is the 3 organ ( I think?!) when you do something sporty or something alike, your pores open and the sweat comes out. It helps you cool down (like letting the sweat come out and no more sweat to loosen up.If the sweat doesn't come out then that leaves you no choise you can either jump around or do something sporty OR, you can be poisened. The liver is a large, important organ. In fact it is the largest internal organ in our bodies. Its numerous functions make it "part" of the circulatory, digestive, and excretory systems. You know what? I don't know. The Excretory means.......... Some proteins & other nitrogenous compounds are broken down in the liver by a process called deamination. The LUNGS is the 1 oCellular respiration occurs in every living cell in your body. It is THE reaction that provides energy (in the form of ATP molecules) for cellular activities. If respiration stops, the cell no longer has energy for cellular activities & the cell dies. As respiration occurs carbon dioxide is produced as a waste product. As the carbon dioxide accumulates in body cells, it eventually diffuses out of the cells & into the bloodstream, which eventually circulates to the lungs. And here, in the alveoli of the lungs, carbon dioxide diffuses from the blood, into the lung tissue, and then leaves the body every time we exhale. We should note that some water vapor also exits the body during exhalation.
