The human body is made up of numerous intricate systems that work together to sustain life. The skeletal system provides a framework for the body's structure and protects vital organs such as the brain, heart, and lungs. The muscular system allows for movement by contracting and relaxing muscles throughout the body. The nervous system enables communication between different parts of the body through electrical signals sent via neurons. The circulatory system transports oxygenated blood to tissues while also removing waste products. The digestive system breaks down food into nutrients that are absorbed into the bloodstream, providing energy for various bodily functions.
