Dear student,
Refer below for above asked query:-

2. Digestion is the process by which large complex food is broken down in into smaller chemical compounds with the help of digestive enzymes that can be absorbed in blood stream and used as nutrients or eliminated by the body.

4. The functions of the tongue in the human body are as the following : - 
A) It helps us to taste the food with the help of taste buds.
B ) It helps to spread saliva over the food so that the amylase can absorb the carbohydrates from the food.
C ) It helps us to transport food from one set of teeth to another set of teeth.
D ) And most importantly it helps us to speak.  

10. Peristalsis   refers to the process by which the food is transported from the buccal cavity to the stomach with the help of the expansion and contraction of the muscles present in the oesophagus. After the peristaltic movement in the oesophagus, food particles move down the oesophagus and reach the stomach.
