The circulatory system includes the heart, blood vessels and blood, and is vital for fighting diseases and maintaining homeostasis (proper temperature and pH balance). The system's main function is to transport blood, nutrients, gases and hormones to and from the cells throughout the body.
Here are 11 fun, interesting and perhaps surprising facts about the circulatory system that you may not know.

What's more, the capillaries, which are the smallest of the blood vessels, would make up about 80 percent of this length.
By comparison, the circumference of the Earth is about 25,000 miles (40,000 km). That means a person's blood vessels could wrap around the planet approximately 2.5 times!

Capillaries are tiny, averaging about 8 microns (1/3000 inch) in diameter, or about a tenth of the diameter of a human hair. Red blood cells are about the same size as the capillaries through which they travel, so these cells must move in single-file lines.
Some capillaries, however, are slightly smaller in diameter than blood cells, forcing the cells to distort their shapes to pass through.
