Question

Accepted Answer

Mouth: The process of digestion starts in the mouth or the buccal cavity. The food is chewed with the help of teeth. The process of chewing the food is called mastication the tongue mixes the food with saliva, that is secreted by the salivary glands located around the throat and in the mouth. The salivary glands secrete digestive juices that begin the breakdown of food. Once the food is chewed, it forms a bolus that can be easily swallowed.

Stomach: The stomach is a muscular sac-like organ. The inner wall of the stomach produces dilute hydrochloric acid, gastric mucosa, and digestive juices. Dilute hydrochloric acid kills microbes that enter with the food. The digestive juices help in the digestion of proteins. The gastric mucosa keeps the inner wall of the stomach safe from the harmful effects of the acids. The food that is partially digested in the stomach is called chyme. This passes into the small intestine.

Liver: It produces bile juice that helps in the digestion of fats. Bile juice is stored in a small sac-like organ below the liver called the gall bladder. It moves from gall bladder to the small intestine when required.

The bile juice helps in the breakdown of fat in the food present in the small intestine. Here, the food is acted upon by the digestive juices is in the liquid form. Most of the digestion of the food happens in the small intestine.

Pancreas: The pancreas is a large cream coloured gland located just below the stomach. The pancreatic juice acts on carbohydrates, fats and proteins and converts them into simpler forms.
