Explain digestive system and its function 

Solution:

The digestive system helps in complete breakdown of food into a form which can be easily absorbed. This provides energy and nutrition for growth and repair.​​​​​​

(i) Mouth: This is the part from where the food enters the body and is chewed up into small pieces by the teeth.
(ii) Oesophagus:   It helps in movement of food into the stomach.

(iii) Stomach:   The stomach stores and mixes the food received from the oesophagus with the gastric juice.

(iv) Small intestine: It helps in breaking down the food so that the nutrients can be absorbed.
(v) Anus : The waste exits the body from anus.
