body systems

Body systems are groups of organs and structures that work together to perform vital functions necessary for life. For example, the circulatory system transports blood and nutrients, the respiratory system facilitates breathing and oxygen exchange, and the digestive system breaks down food for energy. Other systems include the nervous system, which controls body activities through signals, and the muscular system, which enables movement. Each system relies on the others to maintain overall health and balance, highlighting the complexity and interconnectedness of our body's functioning.
