338730 Statement A :
Relaxation of the diaphragm and the inter-costal muscles returns the diaphragm and sternum to their normal positions and increases the thoracic volume and thereby the pulmonary volume.
Statement B :
The volume of air involved in breathing movements can be estimated by using a stethoscope

1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both Statements are correct.
4 Both Statements are incorrect.
