Question

Reathing in humans is driven by all of the following except

A. the diaphragm.
B. air pressure.
C. the muscles connected to the lungs.
D. the muscles attached to the ribs.

Answer 1

B. air pressure.

Air pressure is astoundingly out of the question in the process of breathing. The muscles around the ribs, connected to the lungs and most importantly the diaphragm are the ones that are mainly the factors to contribute and initiate the process of breathing air; the exchange of air.
