Zoology - Digestion and Absorption Question with Solution | TestHub

There is no significant digestive activity in the large intestine.

Functions of the large intestine are,

(i) Absorption of some water and minerals.
(ii) Absorption of certain drugs.
(iii) Secretion of mucus which keeps the waste (undigested) particles together in the form of faeces and lubricates it for an easy passage.

Faeces enter the caecum through the ileocaecal valve. This valve prevents the backflow of faecal matter into the ileum.
