The tunica media is the thickest tunic; it is predominantly muscular in arterioles and most arteries, and it is predominantly elastic in the largest arteries (the so-called elastic arteries such as the aorta and the common carotid).
Which type of blood vessel has the largest lumen?
Structure of blood and blood vessels
| Artery | Vein | |
|---|---|---|
| Wall | Thick, muscular | Thinner |
| Lumen | Small | Large |
| Other features | Thick muscular walls to withstand blood flowing at high pressure as it leaves the heart; the largest artery is the aorta | Contain valves to prevent back flow of blood |

What are the two largest blood vessels called?
These venules become progressively larger vessels called veins. The vena cava are the two largest veins that carry blood into the right upper chamber of the heart (the right atrium).
Which vessel has the strongest pulse?
Carotid pulse: the common or external carotid artery can be palpated in the anterior triangle of the neck. This is one of the strongest pulses in the body.
Which blood vessel has highest pressure?
Blood pressure is highest as its leaves the heart through the aorta and gradually decreases as it enters smaller and smaller blood vessels (arteries, arterioles, and capillaries).
Which type of blood vessel is the smallest?
Capillaries, the smallest blood vessels. Metarterioles, a vessel that links arterioles and capillaries. Venules, a blood vessel that allows deoxygenated blood to return from the capillary beds to the larger blood vessels called veins.
What blood vessel has the smallest lumen?
Capillaries
Which blood vessel is the largest?
aorta
What are the 3 types of veins?
There are three main types of blood vessels: This vast system of blood vessels — arteries, veins, and capillaries — is over 60,000 miles long.
What are the three main types of blood vessels?
- Arteries. Arteries carry oxygen-rich blood away from the heart to all of the body’s tissues.
- Capillaries.
- Veins.
Which blood vessel carries the most blood?
Blood vessels.
- The inferior and superior vena cava bring oxygen-poor blood from the body into the right atrium.
- The pulmonary artery channels oxygen-poor blood from the right ventricle into the lungs, where oxygen enters the bloodstream.
- The pulmonary veins bring oxygen-rich blood to the left atrium.
Why is the carotid artery the strongest pulse?
The carotid artery is the strongest pulse because it is in an artery that is relatively large, close to the skin’s surface and relatively close to the
