coronary arteries
Oxygenated blood is brought to the myocardium by coronary arteries. These arteries are located all around he surface of the heart.
All respiring cells in our body need oxygen for respiration, so oxygenated blood has to travel all around the body in order to reach each of these cells.
Yes, it lacks them. They are found in the surrounding perichondrium.
Well yes and no. It is the first ventricle to receive oxygenated blood to pump out again, as the right ventricle does not receive oxygenated blood to pump. It is not the first chamber to reieve oxygenated blood, this is the left atrium which gather blood and pumps it into the left ventricle. However all the ventricles of the heart has a blood supply (like any other organ to brink nutrients and remove wastes) and all receive oxygenated blood from this supply at the same time.
The heart pumps oxygenated blood only, all deoxygenated blood goes through veins so i think you are thinking about the aorta, which is the most important artery. And the myocardium is just the second layer of the heart, it isn't a part per se.
Yes, it can
The systemic circulatory system supplies blood to all the organs in the body, ensuring delivery of oxygen and nutrients while removing waste products. It does not supply blood to structures like the cornea in the eye or the cartilage in joints, as these receive nutrients through diffusion.
the heart supplies blood to all the body parts by pumping blood
supply oxygen to all organs
All organs have blood vessels as they all need a supply of blood to be viable

Every organ has a blood supply that arrives in an artery, and departs in a vein. All organs depend on a blood supply.
