The esophagus is a muscular tube that goes from your pharynx (throat) to your stomach. It also helps kill harmful bacteria. The esophagus is a tube that connects the throat (pharynx) and the stomach. Food and fluids are propelled through the esophagus not only by gravity but also by waves of rhythmic muscular contractions called peristalsis. Digestion can be divided into three stages – the oral phase (mouth), the gastric phase (stomach) and the intestinal phase (small intestine)– depending on the position of food within the digestive tract. Running from pharynx to the stomach, the main esophagus function is to transfer the bolus (a moist, round and partly digested food mass) from mouth to the stomach. At the end of the esophagus, a muscle called a sphincter controls the entrance to the stomach.

These contractions are produced by an advancing peristaltic wave that creates a pressure gradient and sweeps the bolus ahead of it. Let’s take a look at how the poultry digestive system works. In front of the stomach are the liver, part of the diaphragm, and the anterior abdominal wall. The longitudinal layer continues on into the duodenum, forming the longitudinal muscle of the small intestine.

It is approximately 2 cm (almost 1 inch) in diameter and is surrounded by thick loops of smooth muscle.
