Vedclass · Answer

(C) The correct answer is $C$. Breathing is primarily an involuntary process controlled by the respiratory rhythm center in the medulla oblongata. However,we can exert conscious control over our breathing to a limited extent. It is possible to consciously breathe by using the diaphragm as the primary muscle of respiration while keeping the rib cage relatively still. Option $A$ is incorrect because we cannot remove all oxygen from the lungs. Option $B$ is incorrect as the Eustachian tube connects the middle ear to the pharynx and is not involved in breathing. Option $D$ is incorrect because even after forceful expiration,some air remains in the lungs,known as residual volume $(RV)$.

Which one of the following is a possibility for most of us in regard to breathing,by making a conscious effort?
