>Swallowing of Food The bolus is then passed into the pharynx by an involuntary swallowing action. It is made easier by the presence of mucus along the walls of the alimentary canal. Bolus next moves into the oesophagus. It moves along the oesophagus by contraction of the portion of the oesophagus ..

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..

A well developed digestive system which can take care of the energy requirements of the animal is present. It consists of an alimentary canal and associated structures. The buccal cavity contains teeth, which are of three different types : incisors, premolars and molars. Canines are absen..
