Mechanism of Digestion - Once the food is ingested into the mouth the action of the upper and the lower jaw crushes and grinds the food. This process is called mastification. This also stimulates the production of saliva. Saliva is thoroughly mixed with the food with the action of the jaw..

There are receptors in the wall of the alimentary canal that send reflexes to the brain through sensory neurons. The brain then sends motor impulses through the motor neurons to the target glands or cells. The nervous control of digestion takes place in the following ways- 1) T..

Digestion starts at the mouth with the mandibles and the maxillae chewing the food. It is also acted upon by enzymes of salivary juice, the salivary carbohydrases which partially digest the food. The food is then swallowed with the help of lubrication prov..

Gastric Juice - It is secreted by the secretory glands of the stomach wall. It is highly acidic as it contains hydrochloric acid (HCl). It also contains enzymes like pepsin and renin. Both act on proteins. However, renin is present only in young children. It digests th..
