Capillaries are tiny blood vessels that resemble small veins, often appearing as very thin tubes. They can be red or sometimes green in color. Despite their small diameter, a vast network of capillaries allows a significant amount of blood to flow through them easily. This article explores what capillaries look like, how they function within the circulatory system, and provides resources for further learning, including visual aids to help illustrate their structure.
