Question

What is the role of the stomach in the process of digestion in human beings?

Answer 1

Stomach and its role In Digestion
The stomach is a muscular sac that lies between the easophagus and the small intestine in the upper abdomen. The stomach is not the only part of your digestive system that absorbs food but rather is important for churning food into a consistency that is easier to digest

Functions of Stomach

• The stomach is J-shaped and it can expand to temporarily store food.
• Partial digestion of the food takes place here. The churning action of the stomach muscles physically breaks down the food.
• The stomach releases acids and enzymes for the chemical breakdown of food. The enzyme pepsin is responsible for protein breakdown.
• The stomach releases food into the small intestine in a controlled and regulated manner.
• A network of blood vessels and nerves surrounds the stomach; this is responsible for the regulation of the secretion and the motion of stomach muscles that churns food.

Extra Information:Chewed food passes from the esophagus into the stomach; the flow is somewhat regulated by the esophageal sphincter (an opening)but more importantly depends on how fast you eat and if you are eating both solids and liquids.The crushed and mixed food is liquefied and is pushed through the pyloric canal into the small intestine.
