*Question: Write the process of nutrition in human being.

*Answer:  The process of nutrition are:

• Ingestion
• Digestion
• Absorption
• Assimilation
• Egestion

Definitions:

1. Ingestion: It is the process of taking food into the body.
2. Digestion : This process involves the breakdown of large, insoluble food molecules into small, water soluble molecules.
3. Absorption: At this stage of nutrition, the digested food is absorbed and passes through the intestinal wall into bloodstream.
4. Assimilation: The process of assimilation involves the utilization of the absorbed food. It is taken in by the body cells and is used for energy, growth and repair. Some part of absorbed food is stored in the body for future use.
5. Egestion: The final stage in nutrition is elimination of undigested food from the body. It takes place in solid form as faeces; in liquid form as urine or sweat; or in gaseous form as Carbon Dioxide.
