Cardiac Anatomy

	This image shows the anterior surface of the heart (notice the anterior interventricular sulcus). On this view, you should be able to identify both atria and ventricles. When presented with an actual heart, you should be able to determine which blood vessels you are viewing. Click on the image for a larger picture.
	Posterior view of the heart. On this view you should be able to identify all four chambers of the heart. You also should be able to determine the blood vessels from this view (primarily the vena cavae and pulmonary vein). You can see the coronary sinus in the groove at the top of the posterior interventricular sulcus - click here to see a picture with the coronary sinus labeled. Click on the image for a larger (unlabeled) picture.
	This image shows a heart that has been cut on the right side. The right atrium is visible at the top of the heart. The right ventricle contains the moderator band, tricuspid valve, chordae tendinae, papillary muscles, and endocardium. Click on the image for a larger picture.
	This is an anterior view of a heart that has been sectioned to show both ventricles. Notice the much thicker walls present in the left ventricle compared to the right ventricle. In this image, you should be able to identify the tricuspid valve, bicuspid valve, the chordae tendinae, and papillary muscles. Click on the image for a larger picture.
	This image shows the left ventricle of the heart. In this view you can identify the bicuspid valve, chordae tendinae, and papillary muscles. You can also see the aorta (the vessel sticking out at the top of the heart), the aortic semilunar valves, and the entrance to the coronary arteries. Click here to see a picture with those structures labeled. Click on the image for a larger (unlabeled) picture.

	This picture shows the heart model from the anterior side. You should be able to identify all the same structures as in the sheep heart. You should also be able to identify the aorta, pulmonary artery, superior vena cava, pulmonary arteries, and ligamentum arteriosum. Click the image for a larger picture.
	This shows the model heart from the posterior side. You should be able to identify the pulmonary arteries, inferior and superior vena cavae, and the aorta. Click the image for a larger picture.
	This picture shows the model with the left ventricle and atrium opened. In addition to the above structures, you should be able to identify the bicuspid valve and chordae tendinae.
	This picture shows the model with the right ventricle opened. In addition to the above structures, you should be able to identify the tricuspid valve, chordae tendinae, and the pulmonary semilunar valve. Click on the image for a larger picture.
	This picture shows the model with the right atrium opened. In addition to the above structures, you should be able to identify the superior and inferior vena cavae. Click on the image for a larger picture.
	This image links to a self-quiz, where you can see if you are able to identify all the parts of the circulatory system. Click on the image for the full-size picture.
