ANATOMY

Detailed explanation-1: -The oesophagus is the tube-like structure present in the alimentary canal through which food passes from the mouth into the stomach. The oesophagus acts as an organ for the conduction of food and no digestion occurs here.

Detailed explanation-2: -No digestion occurs in the esophagus. After passage through the esophagus, the bolus will enter the stomach and undergo mechanical and chemical digestion.

Detailed explanation-3: -The statement “The esophagus is digestive in function” is true. The esophagus is a muscular hollow tube that connects the mouth to the stomach, making it the second major organ in the digestive system if ordering by function.

Detailed explanation-4: -The primary function of the esophagus is to transport food entering the mouth through the throat and into the stomach. This function begins at the very beginning of the esophagus, following some taste buds located on the organ, at the upper esophageal sphincter (UES).

Detailed explanation-5: -Digestion works by moving food through the GI tract. Digestion begins in the mouth with chewing and ends in the small intestine. As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules.
