What does posterior mean?
Towards the back / behind
What does lateral mean?
Away from the midline of the body
What does medial mean?

What do the ventricles do?
They are the pumping chambers of the heart and they have thicker walls than the artria.
What does the right ventricle do?
It lumps blood to the pulmonary (lungs) circulation for the lungs.
What does the left ventricle do?
It pumps blood to the systemic circulation for the body.
What does the septum do?
The dividing membrane which separates the right and left sides of the heart tissue.
What does the bicuspid (mitral) valve do?
It’s between the left atrium and left ventricle and blood only flows in one direction.
What is the tricuspid valve?
It’s between the right atrium and right ventricle and blood only flows in one direction.
What is the semilunar valves?
The aortic and pulmonary valves and it between the left ventricle and the aorta and valves prevent back flow of blood.
