That's how many cells are in the human body. These cells are the tiniest functional units in the body. They form your organs, skin, and brain. They are in your blood and your gut.
In fact, the largest human cell is the female ovum (egg) which can be seen with the naked eye!
The longest!? Your sciatic nerve which runs from the base of your spinal cord to your big toe. That can be well over 4 feet!
But how do these cells work?
Physiology Fact Fridays presents the latest in cell microscopy:
Just like muscles, your cells use contractile structures to move material to its destination. Those red actin fibers are "highways" that transport the "semi-trailer truck" green clathrin-coated pits. Remember...this happens in every single cell...Fascinating!
