The jugular veins are the two main veins in the neck returning blood from the brain to the heart. Their arterial counterparts are the carotid arteries.
The coronary arteries supply oxygenated and nutrient filled blood to the heart muscle. There are two main coronary arteries: right coronary artery and left coronary artery. Other arteries diverge from these two main arteries and extend to the bottom portion of the heart.
Tubes that carry blood to the heart are veins. The two major veins that carry blood to the heart are the vena cava and the pulmonary vein.
The left side of the heart pumps blood to the head and body. The right side of the heart pumps blood to the lungs
Pulmonary artery (to the lungs) Aorta (to the rest of the body.)
