What is the functions of the digestive, excretory, respiratory, circulatory, and lymphatic systems, and how do they interact to maintain the body's homeostasis?
Food and liquids are processed by the digestive system. After nutrients are absorbed during digestion, the excretory system removes solid waste products, or feces, through the rectum. The excretory system also works with the respiratory and circulatory systems and removes carbon dioxide (CO2) from the body.
