Digestion and Absorption
* To perform various function of the body
energy is required which is obtained from
Food.
*Food provides energy and organic material
for growth and repair of tissues.
*The water, we take in plays an important
role in metabolic process and also prevent
dehydration of the body.
*The major components of our food are
Carbohydrates, proteins, fats, vitamins and
minerals also required in small quantity.
*The complex food materials (i•e Biomolecules of food ) cannot be utilise by our body in their
original form.
They have to be broken down and converted into simple substance in the digestive system.
The process of conversion of complex food materials to simple absorable forms is called
Digestion and is carried out by our digestive system by mechanical and biochemical (hydrolysis) method.
