Posteroinferior view of the heart

This video tutorial provides an in-depth exploration of the heart's anatomy, focusing on the posterior inferior view. It covers the heart's location, structure, and function, including the apex, aortic arch, pulmonary trunk, and veins. The tutorial also discusses the vena cava, atria, ventricles, coronary sinus, and posterior interventricular sulcus. The video concludes with resources for further learning.

What is the primary function of the heart?

• To store energy
