Question

A small, low-caliber bullet has entered individual's chest at an angle, through the right lung and then the heart. It is now lodged in heart muscle. The surgeon will have to open some closed cavities of the body and enter those spaces to remove the bullet. What is the order of the cavities and the correct cavities that the surgeon will have to open (starting from the outside)?

Answer 1

The surgeon will first have to cut through the skin through the musculature of the chest and into the chest cavity. For them to reach the heart they will have to spread the ribs, and once inside the pleural cavity they will go through the mediastinum then into the pericardium where they will remove the bullet.

Hopefully that helps!
