Heart Coloring Page
The heart works continuously to pump blood throughout the entire body.
It is made up of many muscles.
The muscle of the heart is made of special cells called “cardiomyocyte,” which are arranged into three layers with different orientations.
Inside the cardiomyocyte, there are many sarcomeres that help the cells contract and relax, as well as many mitochondria that produce energy needed for the heart to keep working.
