Use Crayola® crayons, colored pencils, or markers to color the human heart. Color the areas numbered 1 red. They are the arteries. Color the areas numbered 2 blue. They are the veins. Did you know?
The human heart is made up of two different kinds of blood vessels. Blood vessels are hollow tubes that carry blood all over the human body. The body has three kinds of vessels: arteries, veins, and capillaries. In the human heart there are arteries and veins. Arteries carry blood away from the heart, and veins carry blood toward the heart. Capillaries connect the arteries to the veins throughout the body. Fun Fact:
If all the blood vessels from a child's size body were lined up in a row, they would form a line more than 60,000 miles long.
