What is the order of organs in the digestive system, starting from the mouth?

The correct answer outlines the initial pathway that food takes through the digestive system. Starting from the mouth, the process of digestion begins with the mechanical breakdown of food by the teeth, where it is chewed and mixed with saliva. This mixture, known as bolus, is then swallowed and moves into the esophagus, which serves as a muscular tube connecting the mouth to the stomach.

In the stomach, further digestion occurs as the food is mixed with gastric juices, which contain acids and enzymes that further break down the food into a semi-liquid form called chyme. Understanding this sequence is critical, as it summarizes the digestive journey from ingestion to the initial stages of digestion.

The other options do not reflect the correct order of organs in the digestive process, as they either start from incorrect locations in the digestive tract or misplace the order, omitting important steps in digestion. The sequence presented in the correct answer provides a clear, accurate depiction of the pathway of food through the digestive system, beginning from ingestion at the mouth.
