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 mild ectasia of the abdominal aorta?
Ectasia of the abdominal aorta is when the aorta (the large artery in the body that brings fresh blood from the heart to the rest of the body) in the abdomen (area of the body below the chest and above the waist and holds body organs like the stomach and bowels) is dilated or enlarged. Mild ectasia is a reference term to describe how big the dilation of the aorta in the abdomen is.
What is the largest amd main artery in the circulatory system?

What is an abnormal aorta?
an aorta which is not normal ,it can be aneurysm coarctation aorta and etc....
Describe the last stage of the heart cycle?
The last stage of the heart cycle occurs when the bicuspid valve slams shut and the oxygen-enriched blood pumped out of the left ventricle through the aorta. From the aorta, the blood is directed to the body's cells.
