1. THE HEART

4. Left atrium

5. Right ventricle

8. Right atrium The right atrium receives blood from the Superior and Inferior Vena Cava, this is deoxygenated blood The blood flows from there into the left ventricle through the tricuspid valve. Valves are important they keep blood from flowing back into the heart

10. Blood from the left ventricle is pushed out of the heart into the pulmonary artery where it is transported to the lungs

11. There is a valve between the pulmonary artery and the left ventricle-pulmonary valve

17. LAYERS OF THE HEART Epicardium: outermost layer of the heart Myocardium: is the heart muscle Endocardium: innermost layer made up of simple squamous epithelium

19. What structures can you identify?

20. Blood flow through the heart
