Discuss the three kinds of waste that humans must remove from their bodies, and explain why waste removal is important to living organisms.

Your body uses food to keep it growing, learning and healthy. But what happens to the food and other materials you take in when your body is finished with it?

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. Here are some examples for body wastes: Urine, Carbon Dioxide, Excrement, Earwax, tears, sweat and other stuff like tht. Hope this helped, feel free to mark me brainliest. Have a great day!
