Difference Between Vein and Artery

Veins and arteries play a very important role in our lives, since they are vital elements of our bodies. Through them, blood is transported to the body, a liquid tissue that runs through the body to fulfill vital functions, such as breathing. Without them, we could not live.

That is why it is very interesting to learn about them, this is also because we often do not know the most essential characteristics of veins and arteries. In this article we will show the most relevant characteristics of each one and therefore, we will be able to differentiate them and assess their importance.

Come to

We can express that a vein is a conduit that is responsible for transporting blood from the blood capillaries to the heart. Veins often carry deoxygenated blood and carbon dioxide (CO 2 ) back to the heart. However, there are some veins that carry oxygenated blood, but they are few. Similarly, the fact that they transport blood back to the heart implies that there is less pressure on them.

It is usual for the veins to be found at a superficial level, being able to be observed and palpated on the skin of human beings, more specifically on the arms, hands and wrists.

Artery

An artery is described as a conduit whose function is to transport blood from an individual’s heart to the rest of the body. It is evident that the blood carried by the arteries is oxygenated, so the color of the blood tends to be a brighter or lighter red.

Similarly, it can be inferred that since arteries carry blood directly from the heart, the blood pressure in them is higher. This blood pressure varies depending on a high, produced during cardiac contraction, which is called systolic pressure and a minimum pressure or diastolic pressure. Additionally, we can limit that the walls of the arteries are very resistant and also very elastic.

For all the ideas expressed in the text, some differences between vein and artery can be evidenced, which we summarize in the following table:

Come to Artery
A vein is a conduit that carries blood from the body to the heart. An artery is that conduit that is responsible for transporting blood from the heart to the rest of the body.
Most veins carry deoxygenated blood and carbon dioxide (CO 2 ), except the pulmonary and umbilical veins. Veins carry oxygenated blood throughout the body.
In the human body, there are about half as many veins as arteries. In the human body there are approximately twice as many arteries as veins.
Veins are smaller than arteries. Arteries are larger, tougher, and thicker than arteries.
They can be seen superficially on people’s skin, on the arms, wrists, and hands. Their location is deeper, so they are not usually visible.
The color of the blood carried by the veins is usually a lighter or darker red. (Due to the CO 2 they carry). The color of the blood carried by the arteries is usually brighter, brighter, or clearer. (due to oxygen and absence of CO 2 )
They work with lower blood pressure. They work with higher blood pressure.
