Breaking down food into simpler forms is called digestion. Digestion is both mechanical and chemical . In mechanical digestion, food is physically broken down into smaller particles by processes such as chewing. Chemical digestion make..

Digestion is defined as the process by which complex food molecules are broken down into simpler molecules, so that they can be absorbed by the body. Digestion is mechanical and chemical . In mechanical digestion, food is physically broken down ..

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..

Digestion in amoeba is intracellular taking place within the cell. The food taken in remains in a food vacuole or gastric vacuole formed by the cell membrane and small part of the cytoplasm. The vacuoles are transported deeper into the cells by cytoplasmic movements. H..

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..

. The food then moves into the stomach. The opening is controlled by the cardiac sphincter which is a muscular ring. The stomach opens only in response to swallowing. Here the proteins are broken down into proteoses and peptones by the action of pepsin and the soluble milk protein caesino..

. The opening is controlled by the cardiac sphincter which is a muscular ring. The stomach opens only in response to swallowing. Here the proteins are broken down into proteoses and peptones by the action of pepsin and the soluble milk protein caesinogen is degraded into insoluble casein in childre..

Salivary glands - They are glands found associated with the mouth and their secretion is called saliva. Saliva is a slightly alkaline secretion which contains 99% water. It consists of proteins like mucin which serves to lubricate the food and also helps in its passage along the alimentar..

Digestion is actually carried out by enzymes but the secretion of these enzymes is controlled by the nervous system and endocrine syst..
