Veins vs. Arteries
What is Difference between Veins and Arteries? Veins and arteries play a very important role in our lives, as they are charged with maintaining the flow of blood through the body. Both arteries and veins are part of the pulmonary and circulatory system, without which we could not survive.
Although similar in texture and definition, the veins and arteries differ in structure and function. Because of these not so marked differences, there are many people who confuse these two concepts. Below this post is actually all about the difference between veins and arteries.
Difference between Veins and Arteries
If you have doubts about it and want to know a little more about the difference between arteries and veins, continue reading, because then we explain it to you.
The veins are part of the circulatory system, are the blood vessels whose function is to carry deoxygenated blood to the heart; except in the case of pulmonary and umbilical veins, which carry oxygenated blood instead of deoxygenated blood. They are composed of three layers, which are fragile and collapse easily if the blood stops passing through them.
The location of the veins in the body varies from person to person; however, almost everyone has them quite visible under the skin of the wrists and hands. Compared with the arteries, the veins are weaker because they carry blood with low pressure. The veins also receive blood from the capillaries and then exchange the deoxygenated blood with the oxygenated blood.
Arteries are similar to veins, but their function is to transport oxygenated blood from the heart through the whole body (except for the cases of the pulmonary and umbilical veins), that is, their function is opposite to the function of the veins. In the case of the pulmonary arteries, they take deoxygenated blood from the heart and carry it to the lungs where they take the necessary oxygen.
The arterial system works with high pressure, but the peaks of that pressure vary constantly. Finally, both the arteries and the veins work together to create the pulmonary and circulatory systems.
Key differences between Arteries and Veins
- Veins are more fragile than arteries.
- Arteries carry blood from the heart to the rest of the body, while the veins carry blood from the body to the heart.
- The arteries work with high pressure, while the veins work with a lower pressure.
