Question

describe the process of breathing in man?

Answer 1

Breathing is the process of taking in oxygen-rich air and giving out carbon dioxide-rich air. Breathing in is 'inhalation' and breathing out is 'exhalation'. ... This happens because when air enters, the lungs expand and the ribs move outwards. Simultaneously, the diaphragm contracts and becomes flat.
