Medical Video: Coronary Circulation
The heart is a vital organ that functions to receive and pump blood throughout the body. Inside the heart, there is a large blood vessel called a coronary artery. The job of the coronary arteries is to drain oxygen-rich fresh blood from the heart to the heart muscles. Following is a brief description of coronary arteries and their functions.
Coronary arteries are the main blood vessels of the heart
Coronary arteries are one of the three main blood vessels that surround the heart. Arteries have walls that are elastic enough to keep blood pressure consistent.
Based on the picture above, there are two types of coronary arteries contained in the heart, namely:
Main left coronary artery (Left Main Coronary Artery)
The main left coronary artery functions to supply blood to the left side of the heart muscle (ventricle and left atrium). The main left coronary arteries then branch out to form:
- Arteries Left Anterior Descending (LAD), serves to provide blood to the top and left of the heart.
- Arteries Left Circumflex (LCX), the main left artery branch that surrounds the heart muscle and provides blood to the outer and back sides of the heart.
Right coronary artery (Right Coronary Artery)
The right coronary artery is in charge of supplying blood to the right ventricle, right atrium, SA (sinoatrial) and AV (atrioventricular). Right coronary arteries branch into arteries Right Posterior Descendingand acute marginal arteries. Together with LAD, the right coronary artery helps supply blood to the heart septum.
Coronary arteries have several smaller branches, namely marginal obtuse (OM), septal perforator (SP), and diagonals.
Why is coronary artery important?
The coronary artery serves to provide blood supply and oxygen to the heart muscle. Disorders or diseases of the coronary arteries can cause serious health problems. Damage to the coronary arteries can increase the risk of heart attack and death due to lost or reduced oxygenated blood supply to the heart muscle.
What is coronary artery disease?
Coronary heart disease or coronary artery disease is a condition of plaque buildup in the coronary arteries. This buildup can occur slowly and gradually over a long period of time, even for years. This condition is often referred to as atherosclerosis.
This plaque buildup can harden and risk rupture. Broken coronary arteries can trigger blood clots and can also inhibit blood flow. This condition can increase the risk of angina or heart attack. Other risks that can be caused are arrhythmias (heart rhythm problems) and heart failure.
