Realistic human heart with blood vessels - Anatomical heart coloring page

About this coloring page

A realistic human heart with blood vessels is drawn from the front, with the big arteries and veins rising from the top and the small coronary vessels branching over its surface like a tree. This anatomical heart coloring page is a good fit for school science lessons and for older kids who are curious about the body. A common way to color it is red for the vessels that carry blood with oxygen and blue for the ones that bring it back, with the heart muscle in a deeper red. There are no labels, so students can add the names themselves.
