An artery is a blood vessel that carries blood from the heart to the rest of the body. It originated from the left ventricle of the heart and then arches up and descends close to the backbone. Various arteries come from this arch, such as those supplying the head and neck. Aorta then divides into two terminal branches, each one supplying blood to a specific leg.

The main function of an artery is to deliver oxygen-rich blood away from the heart and into the body’s tissues. Unlike veins, which carry waste products and nutrients to other parts of the body, arteries are higher-pressure portions of the circulatory system. Arteries contain more elastic tissue and smooth muscle cells than veins, allowing them to regulate blood pressure. During heart contraction, arterial pressure reaches a high point, but drops back down to its lowest point during the diastolic phase of the heart’s resting state.
The human circulatory system is comprised of arteries, veins, and pulmonary artery. The latter two carry blood from the heart to the lungs, where it is oxygenated. Arteries also carry deoxygenated blood to the lungs, which returns it to the heart via the pulmonary vein. An artery operates at higher pressure than veins and is usually thicker and more elastic. This article will discuss the anatomy of arteries and explain the different types of arteries.
The arteries contain three layers: tunica intima, tunica media, and the inner lining. The tunica intima contains endothelial cells and elastic tissue. Both of these layers control blood pressure and modulate vessel caliber. The tunica media, in particular, regulates the blood pressure by controlling the caliber of the vessels. This varies between a peak pressure during the heart’s contraction and a minimum pressure between two contractions. The arteries that reach the organs undergo further division. The smaller blood vessels have more smooth muscle and less elastic tissue and a hollow internal space, called the lumen.
Veins and arteries are connected to the heart by a closed system of vessels. They carry oxygenated blood while veins carry deoxygenated blood. They are different in their structure, and a healthy heart ensures that blood flows in one direction. The heart pumps oxygenated blood into the largest artery in the human body, the aorta. After it branches into smaller arteries, it ultimately feeds the entire body.
Atherosclerosis, also known as hardening of the arteries, occurs when cholesterol and fat deposits build up on the walls of the arteries. As these deposits build up, they restrict or even block the blood flow in the arteries. The result is a narrowing and reduced blood flow to distant tissues. Eventually, these deposits result in the formation of blood clots, which lead to heart attacks. It is important to note that the plaques are the most common cause of heart attacks.
