Since I had so many pictures the exterior, interior, side, artificial and placement of a heart, I ran out of ideas and I didn't want to draw another heart similar to the ones I've just listed above. A heart valve normally allows blood to flow in only one direction through the heart. There are four types of heart valves in the heart, the mitral valve (bicuspid valve), tricuspid valve, aortic valve and pulmonary valve. References: Wikipedia. Wikimedia Foundation, n.d.

It is not encouraged to make referencing from Wikipedia. Other than that reflect on what your picture represent in more details, like why does it look like that? Why that particular colour and the valves?
