Where in the human body do cells hold the most mitochondria?

In the heart muscle

Background

Each heart muscle cell can hold up to 5,000 tiny power plants called mitochondria. They make the energy the heart needs to pump. No other organ has so many per cell. That is why the heart can beat a whole lifetime without a break.
