Differences Between Arteries and Veins

Differences Between Arteries and Veins

Also Refer:   Aorta vs Pulmonary Artery Arteries and Veins

The arteries are responsible for carrying the oxygenated blood away from the heart to different organs. On the contrary, veins carry deoxygenated blood from different organs of the body to the heart for oxygenation.

Pulmonary veins, systemic veins, superficial veins and deep veins are the four different types of veins found in the human body.

The blood pressure of the arteries is much greater than that in the veins. When an artery is cut, the blood spurts out with very high pressure and can be rapid. On the contrary, when a vein is cut, blood flows from it very slowly and has more time to clot. Therefore, it is less severe than arterial blood loss.

The superficial veins have very little muscle support and are found near the surface of the skin. The deep veins are located near the leg bones in the centre of the legs and are enclosed by muscles.

Inferior vena cava is the largest vein in the human body that carries blood from the lower half of the body to the heart.

Arteries are the blood vessels, which carry oxygen-rich blood away from the heart to all other cells, tissues and organs of the body.

Aorta is the largest artery in the human body. It carries blood away from the heart to different parts of the body.

The three different layers of arteries and veins are:

The innermost layer or tunica intima.

The middle layer or tunica media.

The outermost layer or tunica adventitia.

Olive oil, watermelon, avocado, fish, asparagus, nuts, broccoli, turmeric, etc., are the important food for cleaning the artery.

The branches of Arteries and Veins are connected by very tiny blood vessels called capillaries.

Arteries and Veins are two different types of blood vessels in the circulatory system and are mainly involved in circulating blood throughout the body. However, the two blood vessels are quite different from each other in terms of function. One of the major differences between arteries and veins is that the arteries carry oxygenated blood to all body parts, whereas veins carry the deoxygenated blood to the heart. Read on to explore what are arteries and veins and their differences.

Following are the major differences between arteries and veins:

Arteries are the  blood vessels  that carry blood away from the heart, where it branches into even smaller vessels. Finally, the smallest arteries, called arterioles are further branched into small capillaries, where the exchange of all the nutrients and other waste molecules are carried out. Veins are the blood vessels present throughout the body. They are tube-like, translucent structures that function by carrying deoxygenated blood from the tissues to the heart for re-oxygenation. Compared to arteries, veins are thin-walled.

Involved in carrying pure, oxygenated blood and nutrient-rich blood.

Involved in carrying impure, deoxygenated blood

Consists of three distinct layers, which are rigid, thicker and highly muscular.

Consists of three distinct layers, which are thin and collapsible.

Peripherally located closer to the skin.

Carry blood away from the heart to various parts of the body.

Carry blood towards the heart from the various parts of the body.

High pressure, as the blood flows by the pumping pressure of the heart.

Low pressure, as the blood flows by the capillary action of the veins.

The level of carbon dioxide is high

In downward direction from the heart to the body tissues.

In upward direction from the body tissues to the heart.

Arteries are at a greater risk of certain diseases like angina pectoris, atherosclerosis, etc.

Veins are less susceptible to diseases such as varicose veins.
