Question

A person sitting at rest experiences a temporary cessation of breathing after forced deep breathing for a few minutes. This is due to (A) too much CO2 in the blood (B) too much O2 in the blood (C) very little CO2 in the blood (D) both high O2 and very little CO2 in the blood

Deep breathing rises the O 2 level of the blood. Acidity of blood increases due to excess formation of oxyhaemoglobin. To maintain pH, more free CO 2 changes to bicarbonates and free CO 2 level in blood decreases. The lack of stimulant for inspiratory center, cessation of breathing occurs.
