Vedclass · Answer

(B) Respiration is primarily of two types: diaphragmatic (abdominal) and costal (thoracic/rib-based).In males,diaphragmatic breathing is more dominant,where the diaphragm plays a major role in changing the thoracic volume.In females,especially during pregnancy,the movement of the diaphragm is restricted due to the pressure exerted by the growing fetus in the abdominal cavity.Therefore,to compensate for the limited diaphragmatic movement,females rely more on the movement of the rib cage (costal respiration) to facilitate breathing.
