Artery Arteries (from Greek ἀρτηρία (artēria) , meaning windpipe, artery) are blood vessels that carry blood away from the heart. While most arteries carry oxygenated blood, there are two exceptions to this, the pulmonary and the umbilical arteries.fter travelling from the aorta, blood travels through peripheral arteries into smaller arteries called arterioles, and eventually to capillaries. Arterioles help in regulating blood pressure by the variable contraction of the smooth muscle of their walls, and deliver blood to the capillaries.

Coronary circulation Coronary vessel branches that remain on the surface of the artery and follow the sulci of the heart are called epicardial coronary arteries. The left coronary artery distributes blood to the left side of the heart, the left atrium and ventricle, and the interventricular septum.

Anatomy and Function of the Coronary Arteries The two main coronary arteries are the left main and right coronary arteries. Left main coronary artery (LMCA). The left main coronary artery supplies blood to the left side of the heart muscle (the left ventricle and left atrium). The left main coronary divides into branches:The left anterior descending artery, which branches off the left coronary artery and supplies blood to the front of the left side of the heart.The circumflex artery, which branches off the left coronary artery and encircles the heart muscle. This artery supplies blood to the outer side and back of the heart.he left main coronary artery supplies blood to the left side of the heart muscle (the left ventricle and left atrium). The left main coronary divides into branches:

How the Heart and Blood Vessels Work Arteries are blood vessels that carry blood away from the heart. Because they are under high pressure, arteries have strong elastic walls. The largest artery from the heart is called the aorta. This artery branches into smaller and smaller vessels before finally reaching the tiny capillaries where oxygen and nutrients are delivered to organs and tissues. The other main artery from the heart goes to the lungs where its blood picks up oxygen. Veins are the blood vessels that carry blood back ...

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. 2  Capillaries: Capillaries are the smallest and thinnest of the blood vessels in the body and also the most common.

Heart & Blood Vessels: Your Coronary Arteries The heart receives its own supply of blood from the coronary arteries. Two 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.he rest of the right coronary artery and its main branch, the posterior descending artery, together with the branches of the circumflex artery, run across the surface of the heart's underside, supplying the bottom portion of the left ventricle and back of the septum.

Blood Vessels, Ch. 19 View All. Arteries are the blood vessels that carry oxygenated blood away from the heart. As they move down through the arterial network, they get smaller and smaller like the branches and twigs of a tree. When they have decreased in size to a certain point, we refer to them as arterioles. Arterioles share many of the properties of arteries. They are strong, have a relatively thick wall, and contain a high percentage of smooth muscle. But they also serve another important function.

- 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.

Coronary Arteries and Heart Disease The coronary arteries extend from the aorta to the heart walls supplying blood to the atria, ventricles, and septum of the heart. The coronary arteries supply oxygenated and nutrient filled blood to the heart muscle. There are two main coronary arteries: right coronary artery and left coronary artery.

Picture of the Arteries The arteries are the blood vessels that deliver oxygen-rich blood from the heart to the tissues of the body. 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.

- Small vessel disease, which is also called coronary microvascular disease, is a disease that affects the small arteries in the heart. These small arteries normally expand to provide extra blood to your heart when you are exercising or exerting yourself.They contract when you are at rest.mall vessel disease is not the same as coronary artery disease. Coronary artery disease affects the large arteries in the heart. These large arteries are responsible for carrying oxygen-rich blood to your heart all the time.

Bright Hub Education The largest arteries are closest to the heart and are about the diameter of your thumb. The aorta, which connects to the left ventricle of the heart, is the largest artery in the body. The smallest arteries, called arterioles, are less than 0.5 mm in diameter, meaning they are so tiny that they are barely visible to the human eye.

- First, the blood flows into tubes called arteries. The arteries leaving the heart are thick tubes. But the arteries soon branch again and again to form smaller and smaller tubes. The smallest blood vessels, called capillaries, form a fine network of tiny vessels throughout the body.

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.

Blood Vessels The pulmonary arteries and the aorta are the largest arteries (the aorta is as wide as a thumb!). Some arteries are named for the organ that they supply, such as the hepatic artery (liver) and the coronary arteries (heart). Others have special names, such as the carotid arteries that supply the head and brain.

- Quick Answer. The largest artery in the human body is the aorta, which connects directly to the heart’s left ventricle. There are no arteries inside the heart, but there are many on the exterior of the heart, called coronary arteries. Coronary arteries bring blood directly to the tissues of the heart. Continue Reading

Circumflex artery Circumflex artery. The circumflex artery, fully titled as the circumflex branch of the left coronary artery, is an artery that branches off from the left coronary artery to supply portions of the heart with oxygenated blood. The circumflex artery itself divides into smaller arterial systems.
