Question

Write the role of the mouth and stomach in the process of digestion.

Answer 1

Digestion is the process of break down of complex food substances into simpler and soluble substances.
The role of the mouth and stomach in digestion are as follows:

• Mouth: Digestion begins in the mouth where starch present in the food gets digested into simpler sugars by the action of saliva released from the salivary glands.
• Stomach: Secretes gastric juices which are acidic in nature due to the presence of HCl.
• Gastric juice also helps in breaking down the proteins into amino acids in the acidic medium provided by HCl.
