NUTRITION IN HUMAN BEINGS:

Human beings are heterotrophic omnivorous organisms. They obtain their food from plants, animals and their products by holozoic modes of nutrition.

  • Ingestion: Process of taking food inside the body through mouth.
  • Digestion: Process of conversion of complex food particles into simpler ones by the action of enzymes.
  • Absorption: Process of diffusion of soluble food particles into the blood.
  • Assimilation: Process of utilization of absorbed food by the body cells.
  • Egestion: Process of removal of undigested food from the body.
