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 number of mitochondria in a cell varies with cell type (Eg. Red blood cells have none [this special case allows more space for hemoglobin, enabling cell to carry more oxygen, and also more flexibility to diffuse through capillaries], muscle cells can contain hundreds and liver cells about 1000- 2000 mitochondria).
