Human Coronary and Pulmonary Circulation | ClipArt ETC

This human anatomy ClipArt gallery offers 96 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.

A diagram of how respiration works. A balloon is attached to the end of a small oil lamp chimney. The container is sealed tight with a sealing wax. As the chimney fills with air, the balloon expands, showing a representation of what a lung looks like while it is expanded. As expected, air leaves the balloon when the chimney is not covered, forcing air to leave the "lung". The piece on the right helps to control the air pressure within the container.
