Question
Which organ is used to break down food mechanically?
- Mouth
- Small intestine
- Anus
- Rectum
Hint:
Mechanical digestion involves the breaking down of food particles.
The correct answer is: Mouth
- The mouth is responsible for breaking down food mechanically.
- The food enters the mouth where the process of digestion begins. The teeth chew the food and break it down into simpler substances.
- This process ensures that the consumed food particles are semi-solid or soft so that they can be easily engulfed and the enzymes can easily function on them.
Mechanical breakdown is crucial for the enzymes to act on it. Larger the surface area, the easier it is for enzymes to breakdown the substances.
