Human physiology

Human physiology is the way our bodies work. It's like the way a car works - there are lots of different parts, and they each do something particular to help us stay healthy and stay alive. For our bodies, we have things like organs (like your stomach, heart, and lungs) that help us digest food, have energy, and breathe. We also have muscles and bones that help us move, and nerves that help us think and feel things. All of the different parts work together to keep us healthy and help us live our lives.
