mediastinum

23 04 2008

I found this picture among some others like it, and it just made me wonder at the complexity of the human body. I can’t understand how any of this would happen by chance, accident, or even survival of the fittest.

Chest dissection

The website provided the following caption:

This mediastinum, a central chest compartment located between the lungs, houses the heart. Immediately to the right of the heart is the aorta, the largest artery of the body. To the right of the aorta are groups of blood vessels (one artery and two companion veins) that run between the ribs to distribute blood through the body. The phrenic nerve, which sends messages to the diaphragm to breath, is visible as it crosses the heart vertically.

Note: If you are just utterly grossed out by stuff like this, let me know, comment or whatever, and I’ll not post this kind of material in the future. 🙂
