The heart muscle is supplied by blood vessels called coronaries.
The aorta supplies blood to the heart.

Coronary Arteries
No the pulmonary artery takes blood to the lungs to be oxygenated. The heart is supplied by the coronary arteries.
Arteries carry oxygen from the heart to the body. This is usually oxygen-rich blood which is supplied to the rest of the body after being oxygenated.
BNP
Yes, the brain is supplied with blood that carries oxygen.
The heart is supplied with blood from the superior vena cava (the large vein that flows to the right atrium). This vein carries blood from the systemic circuit (from the body) to the heart so that blood may be oxygenated and recirculated.
The blood that flows through the heart chambers doesn't diffuse through the endothelium so it is necessary for the heart to have its own blood supply which are supplied through the coronary arteries on the surface of the heart or epicardium.
