Answer:
Food enter the pharynx where the stomach break it down further.
Step-by-step explanation:
Once in the pharynx, the bolus next passes down the esophagus. The bolus is moved down the esophagus by rhythmic muscles contracts called peristalsis. At the end of the esophagus is a thick ring of a muscle called a sphincter which allows food to enter the stomach but not from the stomach back into the esophagus. Once the food enters the stomach it is mixed with the digestive juices. The stomach produces stomach acid; hydrochloric acid, and pepsin. Stomach acid activates the pepsin that digests protein into smaller proteins. Proteins are long chains of amino acids that are essential for cell growth and repair.
