Which body system includes the stomach and intestines?
Correct Answer:
Gastrointestinal
Explanation:
The stomach and intestines are part of the digestive system, specifically the gastrointestinal (GI) tract. This system digests food, absorbs nutrients, and forms waste, running from the mouth through the esophagus, stomach, small intestine, large intestine, and out the anus. The other options correspond to different roles: the respiratory system handles breathing, the circulatory system moves blood, and the nervous system controls and coordinates body activities. So the stomach and intestines belong to the gastrointestinal system.
