Arteries and veins are the components of our circulatory system which carry blood around the body. The differences between each are listed below: 1) Since arteries receive blood directly from the heart they must be able to withstand the immense pressure of the blood as it is forced out of the heart. Whereas veins carry blood towards the heart. 2) Blood is under great pressure in arteries; hence it flows fast, in spurts, reflecting the rhythmic pumping action of the heart. In veins the blood is not under great pressure, hence it flows more slowly and smoothly. 3) Arteries have thick and elastic muscular walls. The strength of an artery to resist pressure comes largely from thee elastic fibres. While veins have relatively thin and slightly muscular walls. 4) Arteries have no valves but veins internal valves along their length to prevent back flow of blood. These valves are folds of the inner walls, shaped like half-moons i.e. Semi-lunar valves. Arteries are the carriers of red oxygenated blood (exception: Pulmonary arteries which carry de-oxygenated blood from the heart to the lungs). Whereas veins carry bluish-red de-oxygenated blood (exception: Pulmonary veins which carry oxygenated blood from the lungs to the heart)
1 . In the arteries the blood is under great pressure hence it flows fast and it also split. 2. In the veins The blood is not under a great pressure hence it flows more slowly and smoothly. 3. Arteries are the carries of oxygenated blood. 4. Veins carry bluish-red de-oxygenated blood.
Arteries and veins are the blood vessels that make up the circulatory system. They carry blood from the heart, around the body and back again and also from the heart to the lungs and back again.
An artery carries blood away from the heart so has to withstand the high forces and pressure caused by the strong pumping action of the ventricles. Arteries therefore have thick walls and wide lumens, so they can cope with this pressure and can carry large volumes of blood at any one time.
A vein does not carry blood under high pressure, because the blood that returns to the heart is travelling more slowly. It therefore needs much thinner walls but the main veins still have large lumens as they need to carry large volumes. Tiny capillaries that take and fetch blood from individual cells are sort of half way between the two but are so narrow, it hardly matters.
Veins also have valves, something that arteries never have. This is to prevent blood flowing backwards, which would be a disaster. Blood circulation is strictly a one-way system.
Arteries and veins are what make each organ of our body function. The function of heart is to create fresh blood in our body and when the blood is being created it should reach to the various organs of the body to make them function well. It is at this point where arteries and veins play a vital role.
The function of arteries is to take fresh blood to various parts of the body and as heart pump blood with great force arteries are situated in the inner layer of the body. Otherwise, even if a minor mishap happened and some upper part of the body get cut a major quantity of blood will come out resulting in the death of the person.
Veins also play a vital role in the function of the body as it takes used blood to heart to get refreshed and again supplied to various parts through arteries
Arteries are blood vessels that transport away blood from the heart to the other parts of the human body and it is rich in oxygen (oxygenated). Veins are also blood vessels that carry blood back to the heart from the other parts of the body. It is not rich in oxygen (deoxygenated). Capillaries are blood vessels, that is essential for the exchange of vital materials from tissues to tissues, and is used as a connection between the veins and arteries.
Arteries carry blood away from the heart. Veins carry blood towards the heart./////////Arteries carry oxygenated blood but veins carry deoxygenated blood.//////Arteries do not have valves but veins have one way valves to stop blood flowing backwards.
1) arteries have a thicker wall than veins. 2) veins have valves to prevent back flow arteries do not 3) arteries carry oxygenated blood while veins carry de-oxygenated 4) arteries carry blood AWAY from the heart and veins carry blood TO the heart
Arteries are blood vessels which carry blood from heart to other parts of the body while veins carry blood back to heart. Capillaries are small blood vessels that are responsible for exchange of many things between blood and tissues. For details, visit Blood vessels.
1. In the arteries, the blood is under great pressure which causes the faster motion. 2. In the veins, the blood is not under a great pressure therefore it flows more slowly and smoothly. 3. Arteries carry oxygenated blood. 4. Veins carry de-oxygenated blood.
Most arteries carry de-oxygenated blood The pulmonary arteries doesnt because it goes away from the hear but to the lungs to get oxygenated Pulmonary veins are the exact opposite
