Difference Between Arteries and Veins

Even if you don’t remember much from your high school biology class, you’re probably familiar with the terms “artery” and “vein”. However, you might not understand the difference between them or the role each plays in your body’s overall functioning. You may even think they’re essentially the same thing. Is it true that they both transport blood throughout the body, but they go about this job in very different ways and for a very different purpose. Below, you will find the facts about the differences between arteries and veins.

The most basic explanation of the difference between arteries and veins is that arteries carry oxygenated blood and transport it away from the heart, while veins carry deoxygenated blood and transport it to the heart from other parts of the body. Both play a crucial, although differing roles in the body’s circulatory system, which transports oxygen and nutrients to the cells in the body. This is why it’s important to understand how each functions and how they work together to move blood through the body.

Arteries and veins also differ in their physical structure. For example, veins have valves that are responsible for directing blood flow, while arteries do not. In addition, veins have thin walls and are collapsible while arteries have thick walls and have a more rigid structure than veins do. Plus, blood moves slowly through veins without much pressure, while in arteries the blood moves under higher pressure. Veins also are typically located close to th skin which can make them more visible, while arteries tend to be situated more deeply into the body.

Both arteries and veins come in two types. The two types of arteries are pulmonary, which carry blood from the heart and lungs, and systemic, which deliver blood from other parts of the body to the heart. Their purpose for transporting blood also differs. The blood transported by the arteries is pure and has been filtered, while the blood that moves through the veins is delivered to the heart for purification.

The valves in the veins can dysfunction and lead to vein disease. It is important for a person with vein disease to now the difference between the two and to also know that there are options available to essentially cure the ailment they may have.
