1) Prevent the collapsing of lungs

2) Supply more oxygen to the tissues

3) Control the heart beat

4) Prevent collapsing of heart​

The correct answer is :

2) Supply more oxygen to the tissues

Explanation :

During an emergency, the breathing rate becomes faster so that more and more oxygen is supplied to the tissues of the body.

When there is an emergency i.e. a physical problem arises or there is some vigorous physical activity, then all the tissues and organs of the body start working at a fast pace. The heartbeat increases, and the circulation of blood also becomes faster. At such times the tissues of the body require more oxygen. Due to this, the speed of breathing becomes faster so that more and more oxygen can get to the body and all the parts of the body can function properly.
