For six to ten years-olds. Tito Dok explains what happens when we cut ourselves. The boy Zikki plays with his mother's scissors and cuts his fingers, alerting the blood cells, platelets, and blood vessels in his body. This story explains the respective tasks of the white blood cells, red blood cells, and platelets in stopping the bleeding of Zikki's wound. It shows how they are different from each other – through their looks, size and function- but all of them are equally important to Zikki's body. From this story children will learn the value of unity.
