Infarct
The heart, of couse, but the cause is due to blocked or narrow arteries with blood clots.
The lymph
The circulatory system, including the heart, spleen, liver, and all the veins and arteries.
Yes because when cells are "working together" they form a tissue. So, yes if white blood cells work together they are called a tissue
Arteries ALWAYS bring blood away from the heart. Vein bring it back.
infarct
When blood supply to the heart is blocked what happens is a myocardial infarction which can result in death.
Pulmonary arteries
The coronary arteries are the blood vessels that nourish the heart. Even though blood goes through the heart, that blood is not the way that the muscle itself picks up nutrients and disposes of wastes.
arteries provide oxygenated blood to the tissues they supply. ergo, a coronary artery that is blocked cannot deliver oxygen to the tissue it is supplying, and all that tissue dies... literally dies as in tissue necrosis, cellular death and just becomes a hunk of meat that flaps along with the tissue around it that still does get oxygen and can move. If a large enough piece of tissue dies or if multiple arteries get blocked then heart stops beating and death occurs.
Arteries. AORTA carry blood from the heart {left ventricle} to the tissue.
coronary bypass
Arteries.
Supply blood to the heart tissue.
the middle layer, called the tunica media
When there are high levels of cholesterol in the blood stream, it can collect within the blood vessels causing them to become narrowed or blocked. This is bad enough when in a peripheral artery, but can be lethal if it occurs in the coronary arteries. These are the vessels that provide the blood supply to heart muscle. If they become narrowed, blood struggles to get to the tissue meaning the oxygen level in the tissue becomes depleted and it is at risk of dying. If the coronary arteries become completely blocked the chance of suffering from a heart attack is very high. By helping the blood cholesterol to drop the arteries are not only more protected from becoming more blocked, but may in fact force the cells to take their cholesterol from existing supplies and reduce any existing blockages; this can help reduce the damage that has already occurred.
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).
