stomach. for 3 marks
Answers
food digestion starts in the mouth, the saliva present in the mouth helps to break down the food into smaller compounds by chewing. In the stomach the food is partially digested by churning and after then its mixed with the acids present in the stomach for further digestion.
Explanation:
The stomach is a muscular organ located on the left side of the upper abdomen. The stomach receives food from the esophagus. As food reaches the end of the esophagus, it enters the stomach through a muscular valve called the lower esophageal sphincter.
The stomach secretes acid and enzymes that digest food. Ridges of muscle tissue called rugae line the stomach. The stomach muscles contract periodically, churning food to enhance digestion. The pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.
