Answer:
Capillaries are tiny blood vessels connecting arteries to veins. These blood vessels carry oxygen and nutrients to individual cells.
The capillaries are very thin and highly branched. This helps in the diffusion of gases with all parts of the body as well as helps the supply of blood to every small part of the body.

Answer:
Capillaries, the smallest and most numerous of the blood vessels, form the connection between the vessels that carry blood away from the heart (arteries) and the vessels that return blood to the heart (veins). The primary function of capillaries is the exchange of materials between the blood and tissue cells.
