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.

An increased WBC count is an indicator of high levels of leukocytes in the blood, usually caused by an increased production of these cells in response to an infection or a medical condition. The upper normal limit for leukocytes in the blood is considered to be 11.000 leukocytes per micro-liter of blood. A count that is more than this is considered to be a high white blood cell count. This figure will vary in the case of children, depending on their age and body weight.
