Since blood receive blood directly from the heart, they need to have thick muscular and elastic walls so that
they will be able to withstand the very high pressure of the
blood as it is forced out of the heart.
fibres in the arteries are the main structure which provide the
strength for the artery to resist the high pressure. The nearer
the artery is to
the heart, the thicker is the elastic fibres.
The thick elastic walls also help to maintain the high
pressure of the blood in the arteries. The high pressure help
push the blood along the artery.
