Veins.
They are called Veins just FYI the blood vessels that bring blood away from the heart are called arteries
Blood vessels that bring blood towards the heart are called veins. The veins that are directly connected to the heart are the superior and inferior vena cavae and the pulmonary veins.
Those are called veins.
'Arteries' take blood away from the heart. 'Veins' take blood back to the heart.
Arteries take blood away from the heart, both to the lungs and to the body. In contrast, veins bring blood to the heart.

bring blood around you, as big as the top part of a finger

With one exception, veins carry oxygen-poor blood back to the heart. The largest and last blood vessel they pass through is called the superior vena cava. The exception is the Pulmonary Vein, which carries oxygen-rich blood from the lungs to the heart to be pumped to the rest of the body.
The capillaries are the small blood vessels that surround each alveolus, or air sac.
superior vena cava
Blood vessels in the dermis layer of the skin supply nutrients and oxygen to skin cells. These blood vessels bring in nutrients and oxygen from the rest of the body through the bloodstream.
