coronary arteries
That would be the Carotid arteries.
Nutrients and oxygen have to get to the outside of the heart. So the blood vessels on the outside have that job. The nutrients and oxygen can't get to the cardiac muscle from inside the heart. Blood vessels that lead from the heart that are high in oxygen and nutrients have their first branch off the aorta that goes to these blood vessels. That's how important these vessels are to the heart and how it functions.
The arteries, which are strong, flexible, and resilient, carry blood away from the heart and bear the highest blood pressures THE AORTA...IT THE FIRST "MAJOR" ARTERY THAT LEAVES THE HEART. 2nd would be the Pulmonary Veins (reversed arteries-veins) in the Respiratory system.
myocardium of the heart
The reason it is important that they be the first to leave the aorta is that the arteries are much thicker than veins and can handle the pressure the heart uses to push blood through the body.
systemic aorta
The heart itself is the first organ to receive blood from the cardiovascular system. Its blood vessels stem directly from the base of the aorta.

Arteries
The first vessels that branch off the aorta are called the coronary arteries. These arteries are so important for the heart muscle to work properly that they are the first off the aorta.These arteries give blood to the heart muscle itself. These arteries are also called coronary arteries because they form a crown around the top of the heart with the arteries forming an upside down crown.
