Answer:
Your body has a way of getting rid of excess materials, whether food matter, oxygen, carbon dioxide, water, salt or waste. It is all taken care of by your body systems. These are a complex set of glands, organs, and processes that help to remove the waste materials from your body that are used up, created as a by-product, are no longer needed, or are extra. Your body systems include the kidneys, sweat glands, lungs and rectum. Your nose and eyes also excrete invading dust and foreign materials.
