When an artery to the heart is blocked, it is called a heart attack.
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.
White blood cells like Machrophages or T-cells.
White blood cells engulfing and destroying disease-causing bacteria is an example of immunity.
Polycythemia is the condition of excess red blood cells in the bloodstream. In contrast, anemia is a deficiency of red blood cells.

Granulocytopenia-- A condition characterized by a deficiency of white blood cells.
Anisocytosis is the condition of red blood cells of different sizes.
Agglutunation
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 condition is called "Rouleaux".
