Detailed explanation-1: -Capillaries are the smallest blood vessels in the body. How small are they? About ten of them equal the thickness of one human hair, and most are so small that only one blood cell can pass through them at a time.
Detailed explanation-2: -What is the anatomy of the capillaries? Most capillaries are only about 8 to 10 micrometers in diameter (a micrometer is 0.001 mm). They’re so tiny that red blood cells have to pass through in a single file line.
Detailed explanation-3: -Blood capillaries are the smallest blood vessels. Each capillary is up to a few cells thick to allow diffusion of blood through it to the organs/tissues.
