lungs
This one can be a tricky answer. It could be the lungs if you count them as two individual parts or it can be the lungs and aveoli which are the tiny air sacs within your lungs that also fill up with air when you breath.
no because the lungs help you breath but the heart helps to get blood in your system
If the organ in question is the heart, we can conveniently divide up the heart into the two atria and the two ventricles. Not all organs can be easily analysed in terms of two things. Organs are actually made up of lots of things.
This process was mummification.
Actually the ribs are moving outward and expanding as the lungs fill with air. The expansion of the ribs makes room for more air to enter the lungs.

The diaphragm is a muscle that moves or pushes up your lung when you exhale and down when you inhale in order to allow more space for oxygen to fill your lung. Also, your chest expands as you breath in and relax as you exhale.
No
When the diaphragm contracts and moves lower, the chest cavity enlarges, reducing the pressure outside the lungs. To equalize the pressure, air enters the lungs. When the diaphragm relaxes and moves back up, the elasticity of the lungs and chest wall pushes air out of the lungs.
