Question

Which muscles can help in increasing the strength of breathing?

(a) Arm muscle

(b) Chest muscles

(c) Abdominal muscles

(d) Facial muscle

This question was addressed to me in an online interview.

I need to ask this question from Mechanism of Breathing-1 topic in portion Breathing and Exchange of Gases of Biology – Class 11

Answer 1

Correct answer is (c) Abdominal muscles

To explain I would say: We have the ability to increase the strength of inspiration and expiration with the help of additional muscles called abdominal muscles. This is called as forceful breathing.
