The Heart
● Vessels:
○ The superior and inferior vena cava flow into the right atrium.
○ The pulmonary artery flows out of the right ventricle.
○ The pulmonary vein flows into the left atrium.
○ The aorta flows out of the left ventricle.
● Note how the majority of the vessels are visible posteriorly. Less detail of them is
visible from the anterior view.
○ 1 - right atrium
○ 2 - right ventricle
○ 3 - left atrium
○ 4 - left ventricle
■ A set of coronary vessels show the divide between the right and left
ventricles.
● The aorta and pulmonary trunk (both arteries) can be identified as they lie between
the auricles on the anterior side.
