Contrast the structure of veins and arteries for thickness of muscle and elastic tissue?

The more pressure it uses, the thicker the walls will be.
Veins have very low pressure which means they have thin walls and vice/versa for arteries which have a higher pressure and thicker walls than veins.

Are coronary arteries elastic?
Yes, arteries have elastic lamina.
What is the structure and function of elastic arteries?
Elastic arteries are also known as conducting arteries because they carry large volumes of blood away from the heart. They are large vessels with diameters up to 2.5 cm (1 in.) (Figure 21-2). The pulmonary trunk and aorta, as well as their major branches (the pulmonary, common carotid, subclavian, and common iliac arteries), are elastic arteries. The walls of elastic arteries are extremely resilient because the tunica media contains a high density of elastic fibers and relatively few smooth muscle cells.
How is the structure of arterioles different from that of arteries?
The wall of the arterioles contain less elastic fibers but more smooth muscle cells than that of the aorta and arteries.
Does tunica media of elastic arteries contains more elastic fibers than muscular arteries?
true
The arterioles muscular arteries and elastic arteries are in what position from heart to capillaries?
left ventricle --> elastic arteries (aorta and its larger branches)--> Muscular arteries --> arterioles --> capillaries
Which blood vessels have elastic fibers?
Arteries contain elastic fibres. These are particularly abundant in the large conducting arteries, such as the aorta.
What blood vessels have elastic quality?
The conducting arteries, which are the high pressure arteries (eg. aorta and pulmonary), are high in elastic fibres. These fibres store energy to help to push blood forward during diastole (heart relaxation).
What does the term elastic mean pertaining to arteries?
The term Elastic Arteries usually refers to the ability of blood vessels to dilate and constrict freely.
Why is it important that the arteries have elastic walls?
The elastic walls helps regulate blood pressure.
Do muscular arteries branch into arterioles?
Yes blood passes through Elastic Arteries, Muscular Arteries, and then Arterioles.
Is especially thick in elastic arteries?
tunica media
Walls of large arteries?
elastic connective tissue
