The heart is made up of two upper chambers, the atria, and two lower chambers, the ventricles. The atria are separated by the interatrial septum, and the ventricles are separated by the interventricular septum.
<h3>The cardiac structures</h3>
Between the atria and the ventricles, we find the atrioventricular valves. In the heart, the pulmonary and aortic semilunar valves are also present, located between the ventricles and the pulmonary artery and aorta, respectively. We therefore have four valves in the heart, which prevent the backflow of blood, thus providing for the movement of blood in a single direction.
With this information, we can correlate the cardiac structures in the image and their functions.
