Cardiovascular System Overview
Responsibilities of cardiovascular system: Pumping blood to the body tissues and cells, Supplying oxygen and nutrients to tissues and cells, Removing carbon dioxide and other waste products of metabolism from tissues and cells
Heart Anatomy 
Approximately the size of your fist, Location: Superior surface of diaphragm, Left of the midline, Anterior to the vertebral column, posterior to the sternum
Coverings of the Heart: Anatomy
Pericardium - a double-walled sac around the heart
Function of the Pericardium
Protects and anchors the heart, Prevents overfilling of the heart with blood, Allows for the heart to work in a relatively friction-free environment
Pericardial Layers of the Heart
Epicardium
Myocardium
Endocardium
Heart 
Center of the circulatory system, Enclosed by pericardium, Three layers of the heart: Epicardium, Myocardium, Endocardium
Heart Chambers 
Right atrium and left atrium (Upper chambers, Receiving chambers)
Right ventricle and left ventricle (Lower chambers, Pumping chambers)
Heart Partitions 
Interatrial septum (Separates right and left sides of atria)
Interventricular septum (Separates right and left sides of ventricles)
Heart Valves 
Tricuspid valve (Controls blood flow between the right atrium and ventricle)
Mitral valve (Controls blood movement between the left atrium and ventricle)
Pulmonary valve (Controls blood movement from right ventricle into pulmonary artery)
Aortic valve (Controls blood flow from the left ventricle to the aorta)
Arteries 
Carry blood away from the heart
Veins 
Carry blood toward the heart
Arteries 
Muscular elastic walls, Form arterioles which form capillaries, Carry blood and oxygen to the body cells
Coronary Arteries
Supply blood to the heart muscle, The heart needs a large amount of blood and 5-7% of blood flows through the coronary arteries
