Question

Quizplus · Accepted Answer

The main organs of the digestive system form a tube through the body called the alimentary canal, which includes the mouth, pharynx, esophagus, stomach, small intestine, and large intestine.

Option A is incorrect because the main organs of the digestive system are involved in both mechanical and chemical digestion. Mechanical digestion begins in the mouth with the chewing of food and continues in the stomach with churning and mixing of food.

Option B is incorrect because the main organs of the digestive system, such as the stomach and small intestine, do produce enzymes that aid in digestion. Other organs, such as the pancreas and liver, also produce enzymes that assist in the digestive process.

Therefore, only option C is true about the main organs of the digestive system.
