Human Cell (Typical)
One of 37 trillion building blocks in your body/Scientific Objects
A typical human cell is about 10 micrometers in diameter, though they range from 8 micrometers (red blood cells) to over 100 micrometers (egg cells). Each cell contains about 42 million protein molecules, several thousand mitochondria, and a complete copy of your genome. You are made of approximately 37 trillion of them.
