Which of the following are characteristics of elastic arteries?
Correspondingly, what are the elastic arteries?
Elastic arteries include the largest arteries in the body, those closest to the heart. They give rise to medium-sized vessels known as muscular, or distributing, arteries. Elastic arteries differ from muscular arteries both in size and in the relative amount of elastic tissue contained within the tunica media.
Additionally, what are the 4 major arteries? The Coronary Arteries are the blood vessels that supply blood to your heart. They branch off of the aorta at its base. The right coronary artery, the left main coronary, the left anterior descending, and the left circumflex artery, are the four major coronary arteries.
One may also ask, what are characteristics of arteries?
Characteristic Features of Arteries:Arteries are thick-walled, being uniformly thicker than the accompanying veins, except for the arteries within the cranium and vertebral canal where these are thin. Their lumen is smaller than that of the accompanying veins, Arteries have no valves.
What is the primary function of the elastic arteries?
Elastic arteries are those nearest the heart (aorta and pulmonary arteries) that contain much more elastic tissue in the tunica media than muscular arteries. This feature of the elastic arteries allows them to maintain a relatively constant pressure gradient despite the constant pumping action of the heart.
