What are four organs of the digestive system?

The four main organs of the digestive system include:

1. Mouth: The mouth is the initial part of the digestive system where the process of digestion begins. It includes structures like the teeth, tongue, and salivary glands.

2. Esophagus: The esophagus is a muscular tube connecting the mouth to the stomach. Its main function is to transport food from the mouth to the stomach through peristaltic movements.

3. Stomach: The stomach is a J-shaped organ that serves as a temporary storage site for food. It produces gastric juices containing enzymes and hydrochloric acid to begin the chemical breakdown of food.

4. Small Intestine: The small intestine is the longest portion of the digestive system. It is responsible for most of the nutrient absorption that occurs after the food is broken down further by enzymes from the pancreas and bile from the liver.
