The heart is situated between the lungs with its apex directed toward the left. The thick muscle layer of the heart wall is the myocardium ,which is lined on the inside with a thin endocarium and is covered on the outside with a thin epicardium. The heart is contained with a fibrous sac, the pericardium. the upper receiving chambers of the heart are the atria. The lower pumping chambers are the ventricles. The interventricular septum separates the two ventricles; the interatrial septum divides the two atria. There are three major types of blood vessels, i.e. ,arteries, veins ,and ca
