Which organs are included in the digestive system?

The digestive system is specifically responsible for the breakdown and processing of food within the body, allowing nutrients to be absorbed and waste to be eliminated. The oral cavity, pharynx, and stomach are all essential components of this system.

The oral cavity initiates the digestive process through mechanical and chemical means, such as chewing and salivation. It prepares food for further digestion. The pharynx acts as a pathway for both food and air, ensuring that food can move from the mouth into the esophagus. The stomach is a critical organ where food is mixed with gastric juices, leading to further breakdown and preparation for nutrient absorption once the food reaches the intestines.

This combination of organs works collaboratively to fulfill the function of the digestive system — processing food from entry into the mouth to its subsequent breakdown and transport through the digestive tract. The other options refer to systems or organs that do not belong to the digestive system, focusing instead on areas like the nervous system or urinary system.
