coronary bypass
The pulmonary arteries deliver blood to the lungs from the heart so it can be oxygenated.
When blood supply to the heart is blocked what happens is a myocardial infarction which can result in death.
Arteries carry blood, oxygenated by the lungs, to the cells of the body. Since the heart is a large muscle, its cells need oxygen too. When one of the arteries supplying the heart with oxygenated blood is blocked ("occluded") the oxygen cannot reach the cells supplied by that artery.
The pulmonary arteries transport deoxygenated blood to the left and right lungs. And interesting fact is that the pulmonary arteries are the only arteries that carry deoxygenated blood. All other arteries deliver blood, enriched with oxygen and other nutrients to our body's What_is_the_function_of_the_pulmonary_artery. Conversely, the pulmonary veins transport oxygenated blood from the left and right lungs to the heart, while all other veins carry deoxygenated blood and waste products.Pulmonary arteries carry deoxygenated blood from heart to lungs.
The common cartoid arteries divide to form the internal cartoids and external cartoids. The external cartoids carry blood to the neck and the outside of the skull. The internal cartoids enters the skull to deliver blood to the brain.

Infarct
By definition a stroke affects the brain by blocking small arteries that carry blood to the cells and deliver nutrients and oxygen. These become blocked and the cells that the artery is leading to, die. A similar thing happens when arteries to the heart muscle cells that are blocked causing a heart attack.
The coronary arteries deliver blood to the muscles of the heart.
The blood vessel gets blocked. In the heart, if one of the coronary arteries get blocked by smoking, it can cause a myocardial infarction (Heart Attack).
Coronary artery bypass graft surgery is a surgical procedure in which one or more blocked coronary arteries are bypassed by a blood vessel graft to restore normal blood flow to the heart.
Veins and arteries are found throughout the body. Veins transport "used" or de-oxygenated blood back to the heart whereas arteries deliver oxygenated blood throughout the body.
Arteries carry blood at high pressure, simply because they are linked directly to the heart and lungs.
