Mechanism of Breathing
BIOXI17: BREATHING AND EXCHANGE OF GASES

338738 Inspiration can occur, when

1 Pressure with in the lungs is less than the atmospheric pressure
2 Pressure with in the lungs is more than the atmospheric pressure
3 Pressure with in the lungs and atmospheric air is same
4 No effect of pressure on inspiration

338736 Which respiratory associated muscles would contract if you blow up a balloon?

1 Internal intercostal muscles and external intercostal muscles would contract
2 Diaphragm contracts and internal intercostal muscles would relax
3 Internal intercostal and abdominal muscle would contract
4 External intercostal muscle contract and phrenic muscles would contract.

338737 In breathing movements, air volume can be estimated by

1 Stethoscope
2 Hygrometer
3 Sphygmomanometer
4 Spirometer

2 Normal inspiration and expiration
3 Forceful expiration
4 Normal expiration

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.
