The Stomach
> Food enters the stomach from the esophagus.
> Hydrochloric Acid is produced in the stomach to digest proteins and kill off bacteria.
> Pepsin (a digestive enzyme) is produced to help digest proteins.
> Mucus is produced by glands of the stomach to protect the stomach from its own acid.
> Sphincter muscles control both ends of the stomach to allow food to enter and exit.
> The stomach is made of 3 strong layers of muscle which mixes and mash the food with digestive enzymes.
