What Are the Smallest Arteries Called? The smallest arteries in the body are called arterioles. Arterioles are blood vessels that help to regulate the volume of oxygenated blood available in the capillaries that supply it to tissues and cells.

Cardiovascular System Anatomy The subclavian artery runs into the axillary region where it becomes known as the axillary artery. 1  Arteries and Arterioles: Arteries are blood vessels that carry blood away from the heart. Blood carried by arteries is usually highly oxygenated, having just left the lungs on its way to the body’s tissues.

Left coronary artery The part that is between the aorta and the bifurcation only is known as the left main artery (LM), while the term 'LCA' might refer to just the left main, or to the left main and all its eventual branches. A first septal branch is sometimes described. Additional images

Picture of the Arteries The intima, the inner layer lined by a smooth tissue called endothelium; The media, a layer of muscle that lets arteries handle the high pressures from the heart; The adventitia, connective tissue anchoring arteries to nearby tissues; The largest artery is the aorta, the main high-pressure pipeline connected to the heart's left ventricle. The aorta branches into a network of smaller arteries that extend throughout the body. The arteries' smaller branches are called arterioles and capillaries.

What Is the Posterior Descending Artery? The posterior descending artery, which is also known as the posterior inter-ventricular artery, is a branch of one of the heart's main arteries. In most people, the posterior descending artery branches away from the right coronary artery, which is called right coronary artery dominance. In left coronary artery dominance, the posterior descending artery branches away from the left circumflex artery.

The aorta branches into a network of smaller arteries that extend throughout the body. The arteries' smaller branches are called arterioles and capillaries. The pulmonary arteries carry oxygen-poor blood from the heart to the lungs under low pressure, making these arteries unique. Conditions of the Arteries Atherosclerosis: The buildup of cholesterol (a waxy substance) into what are called plaques in the arteries' walls.

How You Can Outsmart the Widow Maker Artery (Video) Cardiologists get asked a lot of questions by their inquisitive patients, including “What is the widow maker artery?” The left descending artery or LAD has earned a dubious distinction. The low survival rate when patients experience a heart attack there spawned the term “widow maker.”. Advertising Policy.

- In about 50% of humans a third coronary artery (conus artery) arises from a separate ostium in the right sinus. The left main (LM) coronary artery ranges in length from 1 to 25 mm before bifurcating into the left anterior descending (LAD) and left circumflex (LC) branches. The LAD coronary artery measures from 10 to 13 cm in length, whereas the usual nondominant LC artery measures about 6 to 8 cm in length. The dominant right coronary artery (RCA) is about 12 to 14 cm in length, before giving rise to the posterior descending artery(PDA).

- In angioplasty of the aorta (the major abdominal artery) or the iliac arteries (which branch off from the aorta), a small, expandable tube called a stent is usually put in place at the same time. Reclosure (restenosis) of the artery is less likely to occur if a stent is used.

Coronary Microvascular Disease (MVD) Coronary microvascular disease (sometimes called small artery disease or small vessel disease) is heart disease that affects the walls and inner lining of tiny coronary artery blood vessels that branch off from the larger coronary arteries.omen more frequently develop coronary microvascular disease and it occurs particularly in younger women; however, men and women who have coronary MVD often have diabetes, high blood pressure or a family history of cardiomyopathy.

Heart & Blood Vessels: Your Coronary Arteries Collateral circulation is a network of tiny blood vessels, and, under normal conditions, not open. When the coronary arteries narrow to the point that blood flow to the heart muscle is limited (coronary artery disease), collateral vessels may enlarge and become active.wo major coronary arteries branch off from the aorta near the point where the aorta and the left ventricle meet. These arteries and their branches supply all parts of the heart muscle with blood. 1  Left Main Coronary Artery.

Axillary artery The axillary artery is often referred to as having three parts, with these divisions based on its location relative to the Pectoralis minor muscle, which is superficial to the artery. 1  First part - the part of the artery above the pectoralis minor. 2  Second part - the part of the artery that lies behind the pectoralis minor.
