Why is the aorta so thick-walled?
this is because, due to high thickness of left ventricle blood gets into the aorta with high pressure, and if the aortic wall is not thick, high blood pressure in aorta breaks open wall.
What is the significance of the difference in thickness between the wall of the aorta and the wall of the pulmonary trunk?
I answered this question last week... but anyway... the aorta has to accommodate much higher pressures from the left ventricle, ergo it is thicker.
Compare the thickness of the walls of the superior and inferior vena cava and the aorta?
The aorta has significantly thicker walls than the superior and inferior venae cavae as the aorta is an artery that must respond to significant intraluminal pressures whereas the venae cavae are veins that have minimal intraluminal pressure.
What is the largest amd main artery in the circulatory system?

In what portion is aorta divided?
Curved portion , thoracic aorta and abdominal aorta .
