High proportion of elastin in the tunica media, and large amount of collagen in the tunica advetitia. Allows the Aortic arch to stretch during systole, and the elastic recoil allows it to propel blood during diastole, thus a continual supply of blood is given to the tissue, i.e. acts as a pressure resevoire.

Which pathway correctly traces blood as it travels from the aortic arch to the left arm?
Aortic arch ~>left subclavian artery ~> axillary artery ~> brachial artery ( and its profunda).
What are the left branch off the aortic arch?
The three branches off the aortic arch arethe brachiocephalic arteryleft common carotid Arteryleft subclavian Artery.
The aortic arch is closer to the base or the apex of the heart?
the base
What is pulmonary arch?
There is a pulmonary trunk and an aortic arch in the heart. The pulmonary trunk sends oxygen poor blood from the right ventricle up through it to the lungs to gain oxygen and then comes back into the heart via the left atrium.The aortic arch sends out blood to the entire body from the left ventricle.
Which does not receive blood directly from the aortic arch?
Your heart via the coronary arteries
What is tortuous aortic arch?
It is an aortic arch with an aneurysm.
What is the function of the aortic arch?
it carries blood from the dorsal blood vessel to the ventrical blood cell
The aortic arch arches to where as it emerges from the heart?
Is a right sided aortic arch normal?
What is tortuous arch?
It is an aortic arch with an aneurysm.
Is the aortic arch closer to the base or apex of the heart?
The aortic arch is closer to the base of the heart.
What cavity is the aortic arch in?
The thoracic cavity.
Trace blood from aortic arch to left radial artery?
aortic arch - subclavian artery - axillary artery - brachial artery - left radial artery
What are aortic arches function?
The aortic arch is the area in which the aorta bends in order to descend into the body. It also gives way to three major blood vessels. Thus, the "functions" of the aortic arch are:To bend back the main vessel in order to reach the part of the body below the heart itself;To give off 3 major arteries: the brachiocephalic artery, left common carotid artery, left subclavian artery.
The aortic arch arches to what as it emerges from the heart?
left
What is the branch of the aortic arch?
left subclavian artery
Which pathway correctly traces blood as it travels from the aortic arch to the left arm?
Aortic arch ~>left subclavian artery ~> axillary artery ~> brachial artery ( and its profunda).
What is the function of the pulmonary arch?
either the right or the left sixth aortic arch that in the human fetus persists on the right side as the right pulmonary artery and on the left side as the ductus arteriosus and part of the pulmonary trunk
