Answer 2

★ Absorption in different parts of alimentary canal:-

→ Mouth: Certain drugs.

→ Stomach: Water, simple sugars, some drugs & alcohol.

→ Small intestine: Almost all nutrients including minerals, vitamins etc.

→ Ileum is the chief area of absorption due to the presence of villi, it increases surface area of absorption, its great length and coiled nature.

→ Large intestine: Water, some minerals & drugs.

→ The absorbed materials are incorporated into tissues for their activities. It is called assimilation.

→ The undigested substances like plant fibres, dead bacteria etc. form faeces.

→ It enters into caecum through the ileo-caecal valve, which prevents back flow of faeces.

→ Faeces are temporarily stored in rectum and are eliminated through anus. It is called egestion.
