The Human Body

The human body is a complex, integrated system made up of joints, muscles, bones, organs, and tissues that work together to support life. It processes oxygen and nutrients from food, produces energy, and removes waste. The brain controls functions, thoughts, and emotions, while the heart pumps blood to deliver oxygen and nutrients. Lungs absorb oxygen from air, and the skin protects tissues and regulates temperature. Bones provide support, and muscles enable movement. This intricate network maintains homeostasis, allowing us to grow, heal, and respond to our environment efficiently.
