Answer:
Veins carry blood to the heart.
Explanation:
The circulatory system is composed up of blood capillaries that take blood distant from and towards the heart. Arteries take blood aside from the heart and veins bring blood backward to this heart. The circulatory system delivers oxygen, nutrients, and hormones to cells, and eliminates scrap products, like carbon dioxide. These roadways move in one way only, to hold things traveling where all should.
