In humans and most other animals, a blood vessel called an artery transports blood from the heart to one or more body parts. Oxygenated blood is carried by most arteries; the pulmonary and umbilical arteries, which deliver oxygen-rich blood to the lungs and placenta, respectively, are the two exceptions. The arteries are a part of the circulatory system, which is also in charge of getting oxygen and nutrients to all of the cells, getting rid of carbon dioxide and waste products, keeping the blood's pH in the right range, and moving the immune system's proteins and cells around.
The anatomy of arteries can be divided into two categories: macroanatomy, which must be studied under a microscope, and microanatomy, which can be seen at the macroscopic level. Systemic arteries, which carry blood from the heart to the rest of the body, and pulmonary arteries, which carry deoxygenated blood from the heart to the lungs, make up the human arterial system. The tunica externa, also known as the tunica adventitia, is the outermost layer of an artery or vein. It is made of collagen fibers and elastic tissue, and the largest arteries contain vasa vasorum, which are small blood vessels that supply large blood vessels. The tunica externa, on the other hand, has a hazy boundary that separates the majority of the layers. When it meets or touches connective tissue, its normal boundary is considered. The tunica media, or media, that lies beneath this layer is made up of collagen fibers, elastic tissue, smooth muscle cells, and connective tissue itself. The tunica intima, or intima, is the innermost layer that comes into direct contact with blood flow. The artery can bend and fit through the body thanks to the elastic tissue. Endothelial cells make up most of this layer (along with a supporting layer of elastic arteries made of elastin-rich collagen).The lumen is the internal hollow cavity through which blood flows. The vascular system includes arteries. After the blood has been pumped from the heart, they carry oxygenated blood. Additionally, coronary arteries help the heart pump blood by delivering oxygenated blood to the heart, allowing the muscles to work. Except for the pulmonary arteries, which transport oxygenated blood to the lungs for oxygenation (normally, veins transport deoxygenated blood to the heart, but the pulmonary veins also transport oxygenated blood), arteries transport oxygenated blood from the heart to the tissues.
The umbilical artery, which carries deoxygenated blood from a fetus to its mother, is the other unique artery. When compared to other parts of the circulatory system, arteries have a higher blood pressure. During the cardiac cycle, the pressure in the arteries changes. When the heart contracts, it is at its highest and lowest levels. The radial pulse is a pulse that can be felt in various parts of the body as a result of the pressure change. Arterioles collectively have the greatest impact on both local blood flow and overall blood pressure. They are the blood system's primary "adjustable nozzles," and across them, pressure drops the most.
