How do organ systems work together?
For example, after a large meal is eaten, several organ systems work together to help the digestive system obtain more blood to perform its functions. The digestive system enlists the aid of the cardiovascular system and the nervous system. Blood vessels of the digestive system widen to transport more blood. Nerve impulses are sent to the brain, notifying it of the increased digestive activity. The digestive system even directly stimulates the heart through nerve impulses and chemicals released into the bloodstream. The heart responds by pumping more blood. The brain responds by perceiving less hunger, more fullness, and less interest in vigorous physical (musculoskeletal system) activity, which preserves more blood to be used by the digestive system instead of by skeletal muscles.
