What are the 3 functions of blood vessels?
The Three Major Types of Blood Vessels: Arteries, Veins, and Capillaries. Blood vessels flow blood throughout the body. Arteries transport blood away from the heart. Veins return blood back toward the heart.
What are blood vessels?
(blud VEH-sel) A tube through which the blood circulates in the body. Blood vessels include a network of arteries, arterioles, capillaries, venules, and veins.
What are three types of blood vessels and their functions?
There are three kinds of blood vessels: arteries, veins, and capillaries. Each of these plays a very specific role in the circulation process. Arteries carry oxygenated blood away from the heart. They’re tough on the outside but they contain a smooth interior layer of epithelial cells that allows blood to flow easily.
What are the three main types of blood vessels in the body?
This vast system of blood vessels – arteries, veins, and capillaries – is over 60,000 miles long.
What’s the main artery called?
the aorta
The largest artery is the aorta, the main high-pressure pipeline connected to the heart’s left ventricle. The aorta branches into a network of smaller arteries that extend throughout the body. The arteries’ smaller branches are called arterioles and capillaries.
Why are blood vessels so important?
Not only do blood vessels carry oxygen and nutrients, they also transport carbon dioxide and waste products away from our cells. Carbon dioxide is passed out of the body by the lungs; most of the other waste products are disposed of by the kidneys. Blood also transports heat around your body.
What are the parts of blood vessels?
Key Points
- Blood vessels consist of arteries, arterioles, capillaries, venules, and veins.
- Arteries and veins are composed of three tissue layers.
- The thick outermost layer of a vessel (tunica adventitia or tunica externa ) is made of connective tissue.
What is the structure and function of the blood vessels?
It is returned to the heart in the veins. The capillaries connect the two types of blood vessel and molecules are exchanged between the blood and the cells across their walls….Structure and function of blood vessels.
| Arteries | Veins |
|---|---|
| Always carry blood away from the heart | Always carry blood to the heart |
What are the 5 Major blood vessels?
Key points
- The vasculature works with the heart to supply the body with oxygen and nutrients and to remove waste products.
- There are five classes of blood vessels: arteries, arterioles, veins, venules and capillaries.
Which leg has a main artery?
femoral artery
The femoral artery is the major blood vessel supplying blood to your legs. It’s in your upper thigh, right near your groin.
What is the most important artery in the body?
The largest artery is the aorta, the main high-pressure pipeline connected to the heart’s left ventricle. The aorta branches into a network of smaller arteries that extend throughout the body.
What are the three layers of blood vessels?
The vein wall consists of three layers: The tunica intima, the tunica media and the tunica adventitia.
What are the functions of the blood vessels?
The vital function of the blood vessels is protecting against the loss of blood during injuries. Blood vessels are also involved in circulating both oxygenated (poor) and deoxygenated (impure) blood from and to the heart.
Which is a blood vessel that carries blood away from the heart?
An artery is a blood vessel that carries blood away from the heart, where it branches into ever-smaller vessels.

How does vasodilation affect the diameter of a blood vessel?
vasodilation: relaxation of the smooth muscle in the wall of a blood vessel, resulting in an increased vascular diameter. vasomotion: irregular, pulsating flow of blood through capillaries and related structures. vein: blood vessel that conducts blood toward the heart
