Capillaries are very small blood vessels that spread through the organs to deliver the oxygen and nutrients to individual cells.

Capillaries are just wide enough for red blood cells to pass through.

The walls of capillaries are only one cell thick.


A diagram of a capillary.

Capillaries connect the veins to the arteries through organs.


A diagram showing how arteries branch out to form capillaries which then join back together to form veins.
