The main difference between the arteries vs veins is that the arteries carry blood from the heart and in addition to the pulmonary arteries there is oxygenated blood. The color is bright red. When veins carry blood to the heart and there is oxygen-less blood in the blood (except for pulmonary veins and deep red, you cannot feel. Palpitations.
Difference Between Arteries and Veins?
Arteries vs Veins
|1.||Arteries carry blood from heat, carry oxygenated blood except pulmonary artery)||they carry blood to heart, carry deoxygenated blood( except pulmonary vein)|
|2.||no valves present||valves are present|
|3.||they can feel a pulse||they can’t feel pulse|
|4.||further divided into arterioles.||further divided into venules.|
|5.||bright red color||dark red color|
|6.||have elastic walls that expand with surge of blood||thin and less elastic walls|
|7.||blood pumped into single systemic artery called aorta||blood return via interior and superior venae cavae and coronary sinus|
|8.||they are very deep and are protected by tissues||they are also deep and superficial|
|9.||end in blood capillaries||start in blood capillaries|
|10.||if blood is not present, still they do not collapse or cut across.||collapse when there is no blood in it also can be cut across.|
|11.||their pathways are fairly distinct||they have numerous interconnections|
|12.||have predictable drainage or supply||they are just alike arteries except dural sinuses and hepatic portal circulation|
|13.||the blood pressure in side arteries is high||in veins, the blood pressure is low|
|14.||they distribute blood to body organs||collect blood from body organs|
|15.||arteries have small lumen||the veins have large lumen|
|16.||spurty or fast movements of blood with giving pulse||they show sluggish movement of blood|
What are Veins?
Veins are blood vessels that carry blood from all parts of the body to the heart. The blood contained in the veins does not contain enough oxygen, except only carbon dioxide, other than the pulmonary veins or veins that carry oxygen-rich blood from the lungs to the heart. Blood in the veins is called oxygenated blood. Compared to arteries, veins are wider and have valves to stop the flow of blood. The vein wall is unfit.
What are Arteries?
The arteries are blood vessels that carry blood from the heart to various parts or organs of the body. In addition to the pulmonary arteries that deliver oxygen-free blood to the lungs, they also carry oxygen-rich blood. The artery wall is thick and there is no valve.
As the blood vessels closest to the heart, the arteries have to withstand strong physical pressure by forcibly passing blood. They are pulsed with every beat (that’s why your pulse comes from the artery) and thick walls. Veins withstand very little pressure, but they must compete gravity to get blood from the heart back to the organs. Many veins, especially the legs, contain valves to stop the flow and accumulation of blood. Although veins are usually depicted as blue in medical diagrams and sometimes appear blue through pale skin, they are not actually blue. The light makes contact with the skin and oxygen-free blood, a dark red shade that reflects blue tones. The veins seen during operation or in cadaver look almost like arteries.
