Q.
Contraction of diaphragm during inhalation
NTA AbhyasNTA Abhyas 2020Breathing and Exchange of Gases
Solution:
Inspiration is initiated by the contraction of diaphragm which increases the volume of the thoracic chamber in the anteroposterior axis. The contraction of external intercostal muscles lifts up the ribs and the sternum causing an increase in the volume of the thoracic chamber in the dorso-ventral axis.
