It extends from the sternum in front to the vertebral column behind, and contains all the thoracic viscera excepting the lungs. It may be divided for purposes of description into two parts: an upper portion, above the upper level of the pericardium, which is named the superior mediastinum; and a lower portion, below the upper level of the pericardium. This lower portion is again subdivided into three parts, viz., that in front of the pericardium, the anterior mediastinum; that containing the pericardium and its contents, the middle mediastinum; and that behind the pericardium, the posterior mediastinum.

What happens if pulmonary artery is cut?
There are a few ways in which the pulmonary artery might not work properly.
* It leaks - in which case you would probably die (slowly if it were a simple leak, or quickly if it fully ruptured) without surgical care. (Very rare) * It is clogged with a clot - which would probably dislodge and move to the lungs. (Very dangerous, fairly common.) * It doesn't constrict or open properly - would lead to congestive heart failure. (Very common) There are other issues a person may have, and under competent medical care, each of the above can be treated.

The coronary arteries are, like all arteries, part of the cardiovascular system. They can also be considered part of the heart, when looking at things from the standpoint of organs.
Would you die if you got stabbed in the leg?
If the cut transects the femoral artery (a major blood vessel) the wound could be fatal within minutes due to exsanguination. If the cut us at an angle or ragged you can lose consciousness in about 30 seconds for the average adult male and die in about 3 minutes.
What is the difference between afferent and efferent pathways?
The major difference is the direction of travel for nerve impulses. In the afferent nervous system, the impulses are traveling away from the brain - these tend to be motor impulses. In the efferent nervous system, the impulses are traveling towards the brain - these tend to be sensory impulses.

What is the significance of the difference in thickness between the aorta and the pulmonary trunk?
To put it simply:
The blood in the aorta has to go all around the body. Blood in the pulmonary trunk has to go all around the lungs. The body is, obviously, larger than the lungs. This means blood going around the body needs to be "pushed" more. This is because there is more resistance. For example, it's harder to push a car for 1 mile, then it is to push it 1 metre.
Because the blood has to be pushed more, the heart (left ventricle) pumps it out at a higher pressure. Similarly, because the blood going around the lungs doesn't need to go so far, the heart (right ventricle) pumps it out at a lower pressure.
Because the blood in the aorta is at higher pressure than the pulmonary trunk, it needs to have thicker walls. For example a fire hose is thicker than a garden hose because it needs to transport water at a higher pressure.
The aorta contains large amount of smooth muscle and elastic tissue to help it cope with the high blood pressure.
The axillary artery moves oxygenated blood to the the upper limbs, axilla and thorax. :)
