What blood vessel takes rich blood from the lungs and brings it back to the heart?
The pulmonary artery carries deoxygenated blood from the heart to the lungs.
The blood vessels that carry oxygen-poor blood away from the heart?
Major arteries like the aorta transfer oxygenated blood from the heart to the body tissues.
Coronary arteries are those branches from the major aorta that feed the heart with oxygenated blood.
Arteries are the vessels which carry oxygen-rich blood away from the heart, except for the pulmonary artery, which is the only artery (besides umbilical arteries inside of a fetus) that carries deoxygenated blood. The pulmonary artery carries blood away from the heart into the lungs.
The thing that carries oxygen in your blood is the protein hemoglobin.
Arteries always carry blood away from the heart. Veins always carry blood back to the heart. Not all arteries carry high O2 blood. Not all veins carry low O2 blood. They are named for where they go not what they carry.
What to do with broken blood vessel on back of hand from being hit on wire?
With simple injuries the best idea is RICE R: Rest - let the injured area heal I: Ice - ice the area (note: do not put ice in direct contact with skin, use a cloth as a barrier. C: Compression - Ace bandages or other type of wrap on the area E: Elevation - Raise injured area above the heart to decrease blood flow to area thereby decreasing swelling
What the name of the blood vessels that carry blood away from the heart and to the body tissues?
arteries.
however, the capillaries are what exchange materials with the actual cells.
How does vasoconstriction and vasodilation of blood vessels effect blood pressure?
No. Vasoconstriction is a squeezing of the veins. This is like putting your thumb at the end of a garden hose. The constriction of the flow increases the pressure. The water shoots out faster from the hose when your thumb is blocking the way. If the entire hose were to tighten, as in vasoconstriction, the same effect happens.

From Wikipedia: Vasoconstriction
"Generalized vasoconstriction usually results in an increase in systemic blood pressure..."
When drink alcohol the blood vessels become wider what effect does this have on the body?
Causes the oxygen to process slower causing difficulties.
What is nitroglycerin used to do for coronary blood vessels?
No. It is a strong vasodilator. It is used in angina.
What will happen to the blood flowing when the blood vessels are cut?
When blood vessels are cut- the blood will flowout of them. There are 3categories that aremost common: -Scrape or cut - you ride your bike and scrape your knee badly; blood vessels and skin are torn. The blood from the ruptured capillaries, arteries, veins flows out. Eventually a scab will form. -Black and Blue- You bang your arm into a shelf, the vessels under your skin have ruptured and blood leaks out. But, because your skin is not "broken" the blood remains under the layer of skin revealing a blue-ish discoloration (deoxygenated blood cells). -Internal Bleeding- You get into a car accident and break a rib which punctures your lung. You may have ruptured blood vessels within tissue/organ/part of the body that may not be visible. A doctor would be best in this situation.
What are the blood vessels that carry the blood to the heart?
The coronary artery, after it has been oxygenated at the lungs...
What outer layer of blood vessels is composed of connective tissue?
connective
The outer layer of a blood vessel (artery or vein) is called the tunica externa or tunica adventitia.

pericardium is the layer of the blood vessel that is made of tough connective tissue.
Where is the dorsal blood vessel located?
The dorsal blood vessel is located on top of the intestinal track in a worm.
What is the function of the left anterior vena cava?
The main purpose of the vena cava is to carry deoxygenated blood from the lower part of the body to the heart. It carries this blood to the right atrium of the human heart.
A technique of mechanically widening a narrowed or obstructed blood vessel?
Well it really depends on the nature of the narrowing to dictate the particular course of treatment for arterial narrowing (stenosis) or obstruction (atresia). For example, if the stenosis or atresia is congenital (baby is born with it), then the baby will likely undergo a series of corrective surgeries to reconstruct the malformed vessel-- this is especially true with stenosis or atresia of the cardiovascular organs (i.e., aorta and pulmonary artery).
In contrast, when a once healthy and normal vessel has become narrowed or obstructed, it is often due to the presence and buildup of atherosclerotic plaque, likely related to chronic high cholesterol (specifically, LDL), and an angioplasty is performed (balloon inflation and removal to reopen the vessel-- see link below!) and/or a stent is placed to retain the newly widened artery.
Bottom line, it is important to remember that the smooth muscle/connective tissue composition of arteries is what allows them to be strong enough to withstand high-volume flow, but also gives the vessel a high noncompliance, and treatment of arterial stenosis or atresia can sometimes be difficult as a result.
Blood vessels do not carry air. Blood vessels carry blood, and this blood can carry dissolved gas molecules.

What causes a burst blood vessel in palm of hand?
When your hand takes a big blow of force pressure causes to burst
Are veins and arteries the same thing?
The walls of both, arteries and veins, are structured from three layers (Tunica intima, the innermost, - Tunica media, the middle one, - Tunica Adventita, the outermost). They are not the same, though. Arteries transport the blood away from the heart; meaning, they are subjected to high blood pressure. (The pressure the blood exerts on the blood vessel's wall). The difference between the pressure inside an artery and a vein is enormous. The blood in the arteries, leaving the heart has a pressure of 100 %. While the vein, transporting blood back to the heart, has practically no pressure at the end, and had to be helped by one-way valves (to prevent backflow) and muscle pumps, to get the blood back to the heart. For this reason, the middle layer of the arteries have much more developped smooth muscle cells and elastic fibers. They not only make the arteries "stronger", but also help the arteries maintain blood pressure. They expand (when the heart pushes the blood into them) and recoil, (between heart contraction), "transfering" the pressure onto the blood). Veins are, however, more flexible, can partially collapse, and help a good amount "venous reserve" blood. Hope it helps a bit.
What kind of blood vessels carry oxygen and nutrients away from the heart to all parts of the body?
Those are called arteries with the exception of the one going to the lungs, which is called a vein.
Why are the pulmonary arteries and umbilical arteries called arteries instead of blood vessels?
Pulmonary arteries and pulmonary veins are two different items. The pulmonary artery takes deoxygenated blood from the heart and into the lungs so that the blood can be oxygenated. The oxygenated blood then returns to the heart, via the pulmonary veins, in order to be pumped into the system circulation.
Why does blood vessels act like a highway?
To Keep you alive. They travel your Blood around your Body!
What is a blood vessel for teeth?
it lets blood bring food for the nerves and gives the tooth calcium
What are organs that pumps blood through blood vessels?
The heart pumps blood through the body. The heart is an organ which is composed of the cardiac muscle.
Where do you have blood vessels?
ARTERIES
Arteries are blood vessels that carry blood away from the heart. All arteries, with the exception of the pulmonary and umbilical arteries, carry oxygenated blood. Aorta is the largest artery. ARises from heart.
CAPILLARIES
Capillaries are the smallest of a body's blood vessels and are part of the microcirculation. They are only 1 cell thick. These microvessels, measuring 5-10 μm in diameter, connect arterioles and venules, and enable the exchange of water, oxygen, carbon dioxide, and many other nutrient and waste chemical substances between blood and surrounding tissues.
VEINS
In the circulatory system, veins are blood vessels that carry blood toward the heart. Most veins carry deoxygenated blood from the tissues back to the heart; exceptions are the pulmonary and umbilical veins, both of which carry oxygenated blood. They differ from arteries in structure and function; for example, arteries are more muscular than veins and they carry blood away from the heart.
What is a mass of undissolved matter lodged in a blood vessel?
An embolus is a circulating blood clot.
An embolus is a mass of undissolved matter in the blood.
