What are coronary arteries?

Your heart needs to work 24/7 to keep your body systems working. Like any other body tissue, the heart too needs oxygen and nutrients to function efficiently. For this, we have a network of arteries that supply blood to the heart muscles which are called the coronary arteries. There are two chief coronary arteries:

the left and right coronary arteries, that branch out from the aorta near the point where the aorta and the left ventricle meet.

The right coronary artery supplies blood to the right atrium, the right ventricle, a small bottom area of the left ventricle and the back portion of the septum.

The left coronary artery supplies blood to the left atrium and ventricles and the front portion of the septum.

These coronary arteries give out various branches that supply blood to different parts of the heart.

Coronary artery disease:

When there is high level of unhealthy fats in the blood, they gradually start depositing in the insides of the coronary artery vessel wall and form a fatty plaque(atherosclerosis). This gradually narrows the lumen of the coronary arteries which obstructs blood supply to the heart. This condition is called as coronary artery disease. disruption of blood supply to the heart gives rise to a cluster of symptoms, the most important being chest pain or angina.
