Tell me what is the position of the ribs & diaphram in inhaling and exhaling oxygen?

Expert Answer:

During inspiration the muscles attached to ribs contract  as a result ribs move outwards. The diaphragm moves  downward which creates  vacuum in the lungs and a fall in  pressure and sucks  the air from outside.

 The vice versa movement of ribs and diaphragm facilitate exhalation.
