Vedclass · Answer

(A) During respiration,the volume of the thoracic cavity increases during inspiration due to the contraction of the diaphragm and external intercostal muscles. When the thoracic volume reaches its maximum,the lungs are fully inflated with air. At this point,the process of inspiration is complete,and the next phase,which is expiration,is about to begin. Therefore,at the moment of maximum thoracic volume,further inspiration is not possible because the lungs have reached their maximum capacity.
