What is digestion and why is it necessary? Explain. aa far as you can, how the salivary glands, the atomaoh and the pancreas. help in the digestion or food in a mammal.
Digestion is the process of intake of food,"
and preparing it for absorption and assimilation) through the Blood stream from the villi of the intestines in animals or through the water
condusting and food-conducting systems of tas planta
As in animale, food is taken in to supply
materials for growth and maine co to
replacement or rapair of parts, for
move, and for producing sex cells.
Plants synthesize the materiale they need for life and growth from simple substances in the sail and air,
The food therefore must be subjected toTM physical and chemical changes, called digestion, before it can be absorbed and used in the body a living organism."
The food in solution is then reduced from. later molecules into smaller ones which can pass- into the blood stream by diffusion through the mucous membrane of the intestine and the capillaries in the animal's body. Much of chemical work is done later by the enzymen in the digestive tract of an animal.
Ia man, three pairs of salivary glands are situatad in the mouth floor. They asoreta a solution of mucin and ptyalin, The water will dissolve any soluble food, and together with the mucin. The mucin lubri ates the food, helping its passage from the oesophague to the stomach. The ptyalin digests the starch to soluble maltos. In many other animals, the saliva has little or no digestive function.

The trypsin is only formed when trypsinogen is mixed with enterokibase which is secreted by the mucous membrane of the duodenum. The panoreas aleo secretes hormone, inaulin, which regulates the blood sugar in the circulatory system,
All the foods are completely digested in
