This human anatomy ClipArt gallery offers 95 illustrations of human coronary and pulmonary circulation of the cardiovascular system, which includes the organs and vessels involved in the flow of blood through the heart and lungs, where oxygen-depleted blood is sent to the lungs and oxygenated blood returns to the heart. Detailed views of the heart and views showing the relationship between the heart and lungs are also included in this category.
