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.
Coronary circulation is the circulation of blood in the arteries and veins that supply the heart muscle (myocardium). Coronary arteries supply oxygenated blood to the heart muscle. Cardiac veins then drain away the blood after it has been deoxygenated. Because the rest of the body, and most especially the brain, needs a steady supply of ...
The coronary arteries are the arterial blood vessels of coronary circulation, which transport oxygenated blood to the heart muscle. 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 ...
The brachiocephalic artery, brachiocephalic trunk, or innominate artery is an artery of the mediastinum that supplies blood to the right arm, head, and neck. [1][2] It is the first branch of the aortic arch. [3] Soon after it emerges, the brachiocephalic artery divides into the right common carotid artery and the right subclavian artery.
The left anterior descending artery (LAD, or anterior descending branch), also called anterior interventricular artery (IVA, or anterior interventricular branch of left coronary artery) [1] is a branch of the left coronary artery. It supplies the anterior portion of the left ventricle. [2] It provides about half of the arterial supply to the ...
The superficial iliac circumflex artery (or superficial circumflex iliac), the smallest of the cutaneous branches of the femoral artery, arises close to the superficial epigastric artery, and, piercing the fascia lata, runs lateralward, parallel with the inguinal ligament, as far as the crest of the ilium.
The heart is a muscular organ situated in the mediastinum.It consists of four chambers, four valves, two main arteries (the coronary arteries), and the conduction system. The left and right sides of the heart have different functions: the right side receives de-oxygenated blood through the superior and inferior venae cavae and pumps blood to the lungs through the pulmonary artery, and the left ...
There is significant variation between people in the anatomy of the arteries that supply the heart [33] The arteries divide at their furthest reaches into smaller branches that join at the edges of each arterial distribution. [8] The coronary sinus is a large vein that drains into the right atrium, and receives most of the venous drainage of ...
