Usually the aorta doesn't rupture without prior weakening. Either the artery has a weak wall to start with (due to genetic defects in connective tissue and the like) or it has a normal wall but acquired factors such as cholesterol deposition may weaken them. Once the wall is weak, the artery dilates into what is known as an aneurysm, which then ruptures under high blood pressure or slight physical trauma such as a punch to the chest or the abdomen.

Oxygen and carbon dioxide are exchanged by way of the circulatory system. Cells use oxygen for energy and produce carbon dioxide as a waste. Capillaries are where this exchange occurs. Veins carry this product back to the heart. This blood goes to the lungs were you blow off the carbon dioxide and take in oxygen. So the circulatory system and lungs work together to exchange gases.
