Human beings exhibit a holozoic mode of nutrition involving five basic steps i.e., ingestion, digestion, absorption, assimilation, and egestion.

▪Ingestion – Ingestion refers to the intake of food. Ingestion takes place through Mouth

▪Digestion – Digestion refers to the breakdown of ingested food into simpler forms.

▪Absorption – Absorption refers to the process in which digested food is absorbed into the body fluids (Blood & lymph).

▪Assimilation – Assimilation refers to the process in which absorbed food is transported to different cells of the body

▪Egestion – Egestion refers to the process of removal of undigested food from the body

Answer 2

The human digestive system consists of the gastrointestinal tract plus the accessory organs of digestion (the tongue, salivary glands, pancreas, liver, and gallbladder). Digestion involves the breakdown of food into smaller and smaller components, until they can be absorbed and assimilated into the body.
