The myocardium (muscle) that makes up the heart has its own blood supply called the coronary circulation. The coronary circulation comprises two main arteries; the left coronary artery and the right coronary artery. They branch off from the aorta (the biggest artery in the body!) really early on. The left coronary artery branches (into left marginal artery) to supply the left atrium and ventricle (chambers). The right coronary artery branches (into circumflex and left anterior descending) to supply the right atrium and ventricle and a bit of the left ventricle. Extra for experts: the way the coronary circulation is made up can change (just like people can be short or tall) because of genetic variability. So most people (about 70% off the top of my head) are "right dominant," because their right coronary artery branches to form the posterior interventricular artery. Some people are "left dominant" because their left coronary artery branches to form the posterior interventricular artery.
So just remember
Aorta --> left coronary artery --> left marginal
--> right coronary artery --> circumflex + left anterior descending
+ the posterior interventricular artery from either left or right coronary artery
Hope this helps :)
What else can I help you with?
What is the name of the blood vessel which supplies glucose and oxygen to tn heart muscle?
The coronary arteries are the blood vessels that supply glucose and oxygen to the heart muscle. These arteries branch off the aorta and encircle the heart, delivering nutrients and oxygen-rich blood to support proper heart function.
What is the path followed by the blood when it supplies and drains the heart muscle?
The path followed by the blood when it supplies and drains the heart muscle
What blood vessel brings oxygen to the heart muscle?
The coronary arteries are the blood vessels that bring oxygenated blood to the muscle of the heart.
What blood vessel supplies the heart itself with oxygen?
coronary blood vessels.......
What is The path followed by the blood when it supplies and drains the heart muscles?
The path followed by the blood when it supplies and drains the heart muscle
What is the blood vessel on the heart muscle called?
Coronary arteries
Which heart chamber supplies oxgnated blood to the heart muscle?
The left ventricle pumps oxygenated blood into the aorta, one of the first side branches of the aorta are the cardiac arteries that bring blood back to the heart. So no heart chamber supplies blood to the heart directly.
A vessel that that carries oxyogen rich blood to the heart muscle is called?
Pulmonary Vein
Coronary circulation supplies blood to what?
Coronary circulation supplies blood to the heart muscle itself, providing oxygen and nutrients for the proper function of the heart. It is essential for maintaining the health and function of the heart.
What is the name of the artery that supplies blood to the heart to meet the oxygen and nutrient needs of the heart muscle?
heart attack
What is an artery that supplies blood to the heart?
The coronary arteries supply blood to the myocardium (heart muscle).
Trace the pathway of a drop of blood from the myocardium of the heart to the arm?
The myocardium does not have blood flow to the arm. The myocardium is the muscle of the heart and therefore only supplies blood to the heart.
