Explanation:
Aorta is the biggest artery and channels pumped blood from the left ventricle of the heart to tissues. It, therefore, needs to bear the greatest burden of blood pressure because the left ventricle is thicker than the right ventricle and pumps blood with high pressure so that it reached the tissues with the right hydrostatic pressure to allow blood plasma pass through the capillaries walls into tissue fluid.
The walls of the aorta need to be thick enough and elastic to bear the pressure. This is why the <em>tunica media</em> is thickest it aorta because these elastic fibers provide strength and elasticity to prevent rupturing and smooth muscle cells contract and relax in regulation of this pressure to maintain the right pulse.
