- These two arteries branch into other arteries, including the circumflex artery, that also supply blood to the heart. The cardiac veins collect blood from the heart muscle and empty it into a large vein on the back surface of the heart called the coronary sinus, which returns the blood to the right atrium.lood Supply of the Heart. Like all organs, the heart needs a constant supply of oxygen-rich blood. A system of arteries and veins, called the coronary circulation, supplies the heart muscle (myocardium) with oxygen-rich blood and then returns oxygen-depleted blood to the right atrium.

Coronary circulation 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) of the aorta, just after the aorta exits the left ventricle. There are three aortic sinuses (dilations) in the wall of the aorta just superior to the aortic semilunar valve.

- The coronary arteries supply blood to the myocardium (heart tissue) itself; that is, coronary capillaries deliver oxygenated blood (nutrients) to all of the heart's cells. Numerous clinically relevant arterial branches arise from the right coronary artery, including those that supply the conduction system.

The Circulatory System The top of the heart connects to a few large blood vessels. The largest of these is the aorta, or main artery, which carries nutrient-rich blood away from the heart. Another important vessel is the pulmonary artery which connects the heart with the lungs as part of the pulmonary circulation system. The two largest veins that carry blood into the heart are the superior vena cava and the inferior vena cava. They are called vena cava because they are the heart's veins..

Classification & Structure of Blood Vessels One system, the pulmonary vessels, transports blood from the right ventricle to the lungs and back to the left atrium. The other system, the systemic vessels, carries blood from the left ventricle to the tissues in all parts of the body and then returns the blood to the right atrium.apillaries. Capillaries, the smallest and most numerous of the blood vessels, form the connection between the vessels that carry blood away from the heart (arteries) and the vessels that return blood to the heart (veins).

- 1 Arteries are elastic vessels that transport blood away from the heart. 2  Pulmonary arteries carry blood from the heart to the lungs where oxygen is picked up by red blood cells. 3  Systemic arteries deliver blood to the rest of the body. 4  Veins. 5  Veins are elastic vessels that transport blood to the heart.he inner blood vessel layer is formed of endothelium. In capillaries and sinusoids, endothelium comprises the majority of the vessel. Blood vessel endothelium is continuous with the inner tissue lining of organs such as the brain, lungs, skin, and heart. In the heart, this inner layer is called the endocardium.

Arteries and Veins that Feed the Heart It needs its own nutrient and oxygen supply so it can keep beating every day, all day long. A complex system of veins and arteries keep the heart supplied with blood and allow the blood to circulate through the body. Coronary arteries supply the heart with oxygenated blood. The right coronary artery starts from the right aortic sinus and travels through the coronary sulcus located between the right atrium and ventricle. It has four branches: Sinoatrial nodal artery: Supplies the sinoatrial node.

Chapter 23: The pericardium and heart F. Blood Supply to the Heart (Coronary Circulation) Diagram. i. Blood is supplied to the heart by the first two branches of the aorta, right and left coronary arteries. These arteries arise from the base of the aorta and encircle the heart in the atrioventricular groove.

Cardiovascular System Anatomy Coronary Circulation. The heart has its own set of blood vessels that provide the myocardium with the oxygen and nutrients necessary to pump blood throughout the body. The left and right coronary arteries branch off from the aorta and provide blood to the left and right sides of the heart.here are three major types of blood vessels: arteries, capillaries and veins. Blood vessels are often named after either the region of the body through which they carry blood or for nearby structures. For example, the brachiocephalic artery carries blood into the brachial (arm) and cephalic (head) regions.

Which blood vessel sends oxygen rich blood from the heart to the rest of the body? The aorta. The primary blood vessel that transports oxygenated blood from the heart is the aorta. The aorta starts as the ascending aorta from the left ventricle of the heart. It then makes a hairpin bend (called the aortic arch) and becomes the descending aorta.

Blood supply of the Heart The left coronary artery runs between the left atrium and the trunk of the pulmonary artery. It supplies the left atrium, a large portion of the left ventricle, a small portion of the right ventricle, the interventricular septum and the sinoatrial node in approximately forty percent of the population.

Coronary circulation Coronary circulation is the circulation of blood in the blood vessels of the heart muscle (myocardium). The vessels that deliver oxygen-rich blood to the myocardium are known as coronary arteries. The vessels that remove the deoxygenated blood from the heart muscle are known as cardiac veins.he left coronary artery distributes blood to the left side of the heart, the left atrium and ventricle, and the interventricular septum. The circumflex artery arises from the left coronary artery and follows the coronary sulcus to the left. Eventually, it will fuse with the small branches of the right coronary artery.

The Cardiovascular System (Structure and Function) (Nursing) Part 2 Coronary Arteries. Heart muscle requires its own blood supply because heart tissue does not absorb blood from its chambers. Therefore, two coronary arteries (right and left) branch off the ascending aorta to provide blood to heart muscle (Fig. 22-5). Their openings (orifices) lie behind two cusps of the aortic valve. They receive their blood supply during ventricular relaxation, when the valves are closed.

Blood Supply of the Heart The circumflex then continues around the heart, terminating on its posteroinferior aspect, to supply blood to both the left and right atrium. As an aside, in approximatly one-third of patients an intermediate artery will arise between the LAD and circumflex, to supply the anterolaterlal wall of the left ventricle.

The heart and the coronary arteries The heart and the coronary arteries. Coronary arteries are blood vessels that provide oxygen-rich blood and other nutrients to the heart muscle. The coronary arteries attach to and wrap around the heart's surface. The left coronary artery branches off into smaller arteries. The most prominent ones are the: Left anterior descending artery, which supplies blood to the front of the heart. Left circumflex artery, which encircles the ..

- The myocardium is the muscle of the heart. This muscle is supplied by arteries that branch off the aorta. So everytime the heart beats it pushes blood into the aorta and thus … into systemic circulation and thus into the heart wall, as well. These arteries that supply the myocardium are called coronary arteries.

- Conversely, the left side of your heart is responsible for pumping that newly oxygenated blood all of the way down to your fingers and your toes; therefore, the myocardium is much thicker in the left ventricle than the right.
