c) Stomach:
The stomach is one of the main organs of the gastrointestinal tract and digestive system. It is joined to the esophagus at its upper end and to the duodenum at its lower end.
The stomach secretes acid, which kills many harmful microorganisms that might have been swallowed along with the food. and powerful enzymes that break down any protein particles in the food.
After food enters your stomach, the stomach muscles mix the food and liquid with these digestive juices.
After one hour or two, the stomach slowly empties its content, a thick semi-liquid called chyme into the small intestine, where digestion continues.
