This is the heart as we viewed it from the left side of the dog.

Can you trace the circulation of the blood through the heart? When is it oxygenated and when is it deoxygenated?

Identify the labeled structures.

A. Right auricle; B. Left auricle; C. Left atrium; D. Right ventricle; E. Pulmonary trunk; F. Pulmonary artery (remember, this blood is deoxygenated, even though it is in an artery - arteries take blood away from the heart and veins take blood towards the heart, regardless of oxygen content); G. Left ventricle; H. Aorta (aortic arch); I. Brachiocephalic trunk; J. Left subclavian artery; K. Interventricular groove
