The path followed by the blood when it supplies and drains the heart muscle
There are two main blood vessels into which all blood returning to the heart drains, the superior and inferior vena cava. The superior vena cava will drain blood from the upper part of the body into the right atrium and the inferior vena cava will drain blood from the lower part of the body into the right atrium.
The coronary arteries supply blood to the myocardium (heart muscle).
The coronary artery supplies heart muscle with oxygenated and nutrient filled blood
Coronary arteries. The orifice of the coronary arteries are located on proximal part of the ascending aorta, and there are two orifices branching into the left and right coronary arteries.The marginal, anterior and ventricular arteries provide the cardiac muscle with oxygenated blood.The coronary arteries are the major vessels bringing blood to the heart muscle. The are the left and right coronary arteries, the left having a common trunk followed by the circumflex and anterior descending branches. Each of these give off side branches which bring blood and hence oxygen to the heart muscle. Coronary arteries fill during diastole.There is a right coronary artery and the left coronary artery. In total there are four coronary arteries.
It supplies the cardiac muscle with oxygen and other nutrients, but only the left side of the heart

superior vena cava
There are two main blood vessels into which all blood returning to the heart drains, the superior and inferior vena cava. The superior vena cava will drain blood from the upper part of the body into the right atrium and the inferior vena cava will drain blood from the lower part of the body into the right atrium.
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.
Portal vein receives blood from two major veins, Superior mesenteric vein that drains the entire small bowel and splenic vein which drains the entire large bowel and spleen. Portal vein supplies about 60% of the total blood flow to the liver.

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.
The coronary arteries supply blood to the myocardium (heart muscle).
The Heart
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.
Veins are the type of blood vessel that drains blood from tissues and returns it to the heart.
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.
