Physiology of aorta

 

The aorta is the largest blood vessel with a lumen diameter of about 2.5 cm and wall thickness of 2 mm. Its total cross sectional area is however the lowest 4.5 cm2 while its velocity  is the highest. Its relative resistance is also quite low; lower than those of arteries and arterioles.

Windkessel effect is the recoil which occurs at diastole as a result of the elastic nature of the aorta and other elastic arteries called Windkessel vessels. Pulsatile flow of blood allows optimal function of blood perfusion of tissues
