Which organs are included in the gastrointestinal system?

1. Heart and lungs

2. Stomach and intestines

3. Skin and nails

4. Muscles and bones

The correct answer is: Stomach and intestines

The gastrointestinal system, also known as the digestive system, comprises organs that play critical roles in the digestion and absorption of food. The primary organs in this system include the stomach and intestines, which are essential for breaking down food and extracting nutrients. The stomach is responsible for the initial breakdown of food through mechanical and chemical means, while the intestines—both the small and large—are where most of the digestion and nutrient absorption occurs. The small intestine is specifically adapted for nutrient absorption due to its large surface area, while the large intestine focuses on water absorption and the formation of solid waste. Other options do not contain organs that are part of the gastrointestinal system. The heart and lungs are part of the circulatory and respiratory systems, the skin and nails are components of the integumentary system, and muscles and bones belong to the musculoskeletal system. Understanding the specific functions and roles of the organs in the gastrointestinal system is crucial for comprehending how the body processes food and maintains overall health.
