oxygen has to pass through them to make blood rich
they are only one blood cell thick!
Capillaries are one cell thick.

One. Capillaries are only one epithelial cell thick
Capillaries are the tiniest blood vessels in the body with walls that are only one cell thick, allowing for the exchange of gases, nutrients, and waste products between the blood and tissues.
The thin walled blood vessels are called capillaries.
Capillaries. It is only one cell thick (adaptation for diffusion)
Capillaries are only one cell layer thick, which allows for the exchange of nutrients and gases between the blood and tissues. This thin structure promotes efficient diffusion and transport across the capillary walls.
capillaries, since they are only one cell wide.
capillaries
Arteries, veins and capillaries are the three major types of blood vessels. Capillaries are very small and only one cell thick to allow O2/CO2 exchange. Nutrients and wastes are also exchanged.
it comes in arterial blood and leaves as venous blood
