Class : Class 1

The correct answer is A.

When food is taken in the mouth, it is chewed and gets mixed with saliva secreted in the mouth (R). Once swallowed, the food moves through the oesophagus into the stomach where churning and digestion of food with digestive juices occurs (Q). The semi-digested food then moves into the small intestine where complete digestion as well as absorption of nutrients occur (S). From the undigested food, the water is absorbed in the large intestine (P). After this, the undigested food is expelled through the anus in the form of faeces (T).
