Process of Digestion: In Mouth and Oesophagus -

 
  • The process of digestion is accomplished by mechanical and chemical processes.
  • The buccal cavity performs the mastication. It is the process of biting and grinding the food with the help of teeth and saliva.
  • Mastication is followed by deglutition. It is the process of swallowing the masticated food (bolus). 
  • The swallowed food is pushed down to the alimentary canal with the help of peristalsis.
  • The gastro-oesophageal sphincter controls the passage of food into the stomach.
  • The saliva secreted into the oral cavity contains electrolytes and enzymes, salivary amylase and lysozyme.
  • The chemical process of digestion is initiated in the oral cavity by the hydrolytic action of the carbohydrate splitting enzyme, the salivary amylase. 
  • About 30 per cent of starch is hydrolysed here by this enzyme (optimum pH 6.8) into a disaccharide – maltose. 
  • Lysozyme present in saliva acts as an antibacterial agent that prevents infections.

 

The chemical process of digestion is initiated in the oral cavity by the hydrolytic action of the carbohydrate splitting enzyme, the salivary amylase. Hence, the correct answer is option a.
