Question

Name the five steps which occur in the process of nutrition in animals.

Answer 1

1. Ingestion: The process of taking food into the body through the mouth (or other specialized structures depending on the organism).
2. Digestion: The breakdown of complex, large food molecules into simpler, soluble molecules that the body can process.
3. Absorption: The process by which the digested, soluble nutrients pass through the intestinal walls into the bloodstream or body fluids.
4. Assimilation: The transportation and utilization of these absorbed nutrients by the body’s cells to produce energy, build new tissues, and repair damaged ones.
5. Egestion: The removal or elimination of undigested and unabsorbed solid waste material from the body.
