2.27 understand the processes of ingestion, digestion, absorption, assimilation and egestion

  • Absorption – process by which soluble molecules produced by digestion are taken from the gut (usually the small intestine). Soluble products of digestion are then transported to the various tissues in the circulatory system
  • Assimilation – process by which some of the absorbed food materials are converted into new protoplasm or used to provide new energy
  • Digestion – the process where large food molecules are broken down into small, soluble and diffusible molecules that can be absorbed by the body’s cells
  • Egestion – the removal of undigested matter from the body as feces from the anus
  • Ingestion – the consumption of a substance by an organism
