The anatomy of arteries can be separated into gross anatomy, at the macroscopic level, and microanatomy, which must be studied with a microscope.The arterial system of the human body is divided into systemic arteries, carrying blood from the heart to the whole body, and pulmonary arteries, carrying deoxygenated blood from the heart to the lungs.
The heart requires a continuous supply of oxygen to function and survive, much like any other tissue or organ of the body. [1] The coronary arteries wrap around the entire heart. The two main branches are the left coronary artery and right coronary artery. The arteries can additionally be categorized based on the area of the heart for which ...

Coronary arteries labeled in red text and other landmarks in blue text Schematic view of the heart. Coronary arteries supply blood to the myocardium and other components of the heart. Two coronary arteries originate from the left side of the heart at the beginning (root) left ventricle.
People who are experiencing aortic dissection, meanwhile—a tear in one of the body’s major arteries—describe sudden, stabbing pain in the middle of the chest that radiates to their back. It ...
The tunica media may (especially in arteries) be rich in vascular smooth muscle, which controls the caliber of the vessel. Veins do not have the external elastic lamina, but only an internal one. The tunica media is thicker in the arteries rather than the veins. The outer layer is the tunica adventitia and the thickest layer in veins. It is ...
Depiction of the heart, major veins and arteries constructed from body scans. Oxygenated blood enters the systemic circulation when leaving the left ventricle, via the aortic semilunar valve. [15] The first part of the systemic circulation is the aorta, a massive and thick-walled artery.
