Ingestion: The intake of food is called ingestion. Method of ingestion, i.e. taking of food, varies from one animal to another.
Egestion: Removal of waste materials from the body is called egestion. The faecal matter is removed through the **** from time-to-time. Since the waste of food left after digestion is also called faeces, hence the process of egestion is also known as defecation.

The food that we consume are not in a form that the body can use as nourishment. Our food and drink must be changed into smaller molecules of nutrients before they can be absorbed into the blood and carried to cells throughout the body. Digestion is the process by which complex food materials are broken down into simple ones, so that they can be easily absorbed and transported to all parts of the body. Now it is possible for our body to use them to build and nourish cells and to provide energy.
The energy cannot be stored because it is for utilization.The form in which energy is stored in the cell is ATP.

The gall bladder temporarily stores bile.
Liver (the largest gland in human body) secretes bile juice that is stored in a sac called the gall bladder. The bile helps in the digestion of fats.
The bile plays an important role in the digestion of fats.The pancreas is a large cream coloured gland located just below the stomach.The pancreatic juice acts on carbohydrates, fats and proteinsand changes them into simpler forms.The partly digested food now reaches the lower part of the small intestine where the intestinal juice completes the digestion of all components of the food. The carbohydrates get broken into simple sugars such as glucose, fats into fatty acids and glycerol, and proteins into amino acids.
