Character
The Common Vein Copyright 2007
The aortic wall, with its high elastic content supported by muscle and collagen, allows for transmission of a more or less steady blood pressure within the circulation by providing a tensile strength that can be adjusted to conform to the pumping strength of the heart muscle
Ascending Aorta
Annulus
The annulus is strong and fibrous
Sinuses
The sines have the same character as the aortic wall in general but it is their pocket like shape that characterises them.
Tubular Portion
The tubular portion is elastic and strong with smooth glistning endothelial surface in the young with progressive roughening of the surface with age and wear.

Aortic Arch
The arch retains the characteristics of the aorta as described above for the tubular portion. ie it is strong, elastic with a smooth endothelial lining
Thoracic and Abdominal Aorta
The same characteristics of strong pliable elastic wit smooth glistening surface pertain.
