This weak spot is called an aneurysm. In the aorta it is called an aortic aneurysm.
An aneurysm is a ballooned, weakened arterial wall.
As more and more fat attaches to the aortic wall, the wall itself becomes abnormally weak and often results in an aneurysm or bulge.
A condition that fits this description is aortic aneurysm. This is when there is a bulge in the wall of the aorta, which can lead to the artery rupturing if left untreated. Risk factors include genetics, high blood pressure, and atherosclerosis.
If weakness develops between the inner and outer layers of the aortic wall, a bulge results as blood from the interior of the vessel is pushed around the damaged region in the wall and collects between these layers.
You need to read your question and ask it again.
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.

Colagen.
To do this you would need to know the area of a brick and the area of the wall. Then you divide the area of the wall by the area of a brick. There are approximately 60 bricks per square metre.
Calcification of the non aneurysmal aorta means that a plaque like substance has built up on the artery wall. This may or may not be a serious medical problem. Only a medical professional will be able to know for sure.
I answered this question last week... but anyway... the aorta has to accommodate much higher pressures from the left ventricle, ergo it is thicker.
