What are the Structural Arteries and Veins

Veins and arteries play a very important role in our lives, since they are responsible for 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. What are the Structural Arteries and Veins

Although they are similar in texture and definition, veins and arteries differ in structure and function. Due to these not so marked differences, there are many people who confuse these two concepts.

If you have doubts about it and want to know a little more about the difference between arteries and veins, keep reading, because we will explain it to you below.

VEINS  What are the Structural Arteries and Veins

Veins are part of the circulatory system, they are blood vessels whose function is to carry deoxygenated blood to the heart; Except in the case of the pulmonary and umbilical veins, which carry oxygenated instead of deoxygenated blood.

They are made up of three layers, which are brittle and easily collapse if blood stops passing through them.

The location of veins on the body varies from person to person, however, almost everyone has them quite visible under the skin of the wrists and hands.

Compared to arteries, 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 one.


Arteries are similar to veins, but their function is to transport oxygenated blood from the heart throughout the body (except in the cases of the pulmonary and umbilical veins), that is, their function is opposite to the function of the veins. veins. In the case of the pulmonary arteries, they take deoxygenated blood from the heart and carry it to the lungs where they take in the necessary oxygen.

The arterial system works with high pressure, but the peaks of this pressure vary constantly.

Ultimately, both arteries and 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 veins carry blood from the body to the heart.
  • The arteries work with high pressure, while the veins work with a lower pressure.
