what happens if our heart is situated in the abdominal cavity rather than in the thorasic cavity?
Answers
Explanation:
In general, the aortic arch in the thoracic cavity has three primary branches: the brachiocephalic artery (which is divided into the right common carotid artery and right subclavian artery), the left common carotid artery, and the left subclavian artery. However, this so-called “normal” configuration of aortic branches may not exist in all humans. Based on a study involving 1000 cadavers, Liechty et al. (1957) concluded that only 64.9% of the general population had a “normal” aortic anatomy . In other words, an FE thorax model with the “normal” aortic configuration represents the most common variation of these large blood vessels, but such a model cannot be used to accurately simulate the other 35.1% of the population. Additionally, attempting to assess risks of injury to these large blood vessels may be further complicated by the fact that as many as 15 possible variations of the aortic arch branches exist.
