An embolus is a particle that moves about in our blood vessels, either in the veins or arteries. Most emboli are composed of clotted blood cells. A blood clot is called a thrombus and a moving blood clot is called a thromboembolus. As an embolus moves through the body's blood vessels, it's likely to come to a passage it can't fit through. It lodges there, backing up blood behind it. The cells that normally get their blood supply via this passage are starved of oxygen (ischemia) and die. This condition is called an embolism.

The total white blood cell count normally ranges between 4,000 and 11,000 cells per microliter. The proportion of each of the five major types of white blood cells and the total number of cells of each type can also be determined in a given volume of blood. Too few or too many white blood cells indicates a disorder. Leukopenia, a decrease in the number of white blood cells to fewer than 4,000 cells per microliter of blood, makes a person more susceptible to infections.
