The human body relies on four key systems - the digestive system, respiratory system, circulatory system, and excretory system - to carry out the vital function of nutrition. The digestive system breaks down food for absorption. The respiratory system absorbs oxygen and releases carbon dioxide. The circulatory system transports blood throughout the body with the help of the heart. And the excretory system, including the kidneys, eliminates bodily wastes. Maintaining a balanced diet, exercise, hygiene, and social interaction are important for overall health.
