in animals digestion functions as a mechanism for

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 ..

Digestion - breaking down food into simpler forms. Digestion is both and chemical . The digestion may take place outside cells ( extracellular ) or within the cells ( intracellular ). Absorption - Taking in of food in the soluble forms into the tissues. The absor..

Renin is present only in young children. It digests the milk protein, casein. Casein is hydrolysed into paracasein which gets precipitated as insoluble calcium paracaseinate. This is called coagulation. Renin secreted by the gastric mucosa of the calf is extracted to make rennet tab..

Saliva is thoroughly mixed with the food with the action of the jaws, teeth, inner walls of cheeks and tongue. The food is formed into bolus..

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 ..

Water moves through the gills by the coordinated action of mouth and the operculum. Taking in water and thereby oxygen is called inspiration and exit of water is called expiration. Mechanism of Respiration in F..

The first four pairs of spiracles are involved in inspiration or drawing in of air (that is oxygen-rich). This air passes through the trachea and the air sacs to reach the tracheoles. Mechanism of Respiration in Insects The ends of the tracheoles are filled with fluid. This end enter..
