Poop – Human Excretory System Basics
Every day your body takes in air, food and liquid. Your body uses most of these materials to grow and get energy. But your body can’t use every bit. Food, liquid and air contain some things that your body can’t use. The leftover material is known as waste.
Think about what would happen if you never emptied the trash. The trash can would fill up and overflow. Your room would start to smell funny. You probably wouldn’t want to spend time there. Our bodies are the same way. Every day our bodies make waste. We must get rid of the waste to stay clean and healthy.
Your body gets rid of waste in three ways. When you breathe out, or exhale, waste from the air is released. When you go pee, liquid waste or urine is released. When you poop, solid waste leaves your body.
