Hi there!
Unfortunately I’m going to be unable to provide a clear precise answer as the true answer is that we don’t know. In a normal adult body, we have some 100,000 estimated miles of blood vessels, which are divided between capillaries, veins, and arteries. Veins are classified as any blood vessel that carries blood back to the heart. It is near impossible to count all veins, due to differences in body structure and the inconsistency of blood vessels as a whole.
