ANATOMY

Detailed explanation-1: -Esophagus: The esophagus is a muscular tube that connects the pharynx (throat) to the stomach. The esophagus contracts as it moves food into the stomach. A “valve” called the lower esophageal sphincter (LES) is located just before the opening to the stomach.

Detailed explanation-2: -The food pipe is also called the oesophagus or gullet.

Detailed explanation-3: -The oesophagus is the medical name for the gullet, which is part of the digestive system. The oesophagus is the long tube that carries food from the throat to the stomach. The top part of the oesophagus lies behind the windpipe (trachea). The bottom part runs down through the chest between the spine and the heart.

Detailed explanation-4: -Peristalsis is a series of wave-like muscle contractions that move food through the digestive tract. It starts in the esophagus where strong wave-like motions of the smooth muscle move balls of swallowed food to the stomach.

Detailed explanation-5: -Swallowed food is pushed into the esophagus, which connects the throat above with the stomach below. At the junction of the esophagus and stomach, there is a ringlike muscle, called the lower esophageal sphincter, closing the passage between the two organs.
