Question

how do the arteries and veins reach the the smallest part of the body​

Answer 1

Explanation:

At each body part, a network of tiny blood vessels called capillaries connects the very small artery branches to very small veins. The capillaries have very thin walls, and through them, nutrients and oxygen are delivered to the cells. Waste products are brought into the capillaries.
