Beside this, what are the coronary arteries and veins?
The coronary arteries are responsible for carrying nutrient rich, oxygenated blood from the left ventricle to the myocardium; while the coronary veins take nutrient – poor deoxygenated blood away from the myocardium and to the right atrium.
Furthermore, which coronary arteries perfuse what areas of the heart? 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.
Right Coronary Artery (RCA)
- Right atrium.
- Right ventricle.
- Bottom portion of both ventricles and back of the septum.
Correspondingly, what are the coronary veins?
The coronary veins return deoxygenated blood from the myocardium back to the right atrium. Most venous blood returns via the coronary sinus. Coronary venous anatomy is highly variable, but is generally comprised of three groups: cardiac veins which drain into the coronary sinus: middle cardiac vein.
What is the role of the coronary arteries?
Coronary arteries supply blood to the heart muscle. Like all other tissues in the body, the heart muscle needs oxygen-rich blood to function. Also, oxygen-depleted blood must be carried away. Small branches dive into the heart muscle to bring it blood.
