Blood & Cardiovascular System
Anatomy of the Heart
Valves
Mitral Valve
Control blood flow from Atriums to ventricles
Aortic Valve
Control Blood flow out of ventricles
Pulmonary Valve
Tricuspid Valve
Chambers
Left & Right Atria
Left Atrium receives blood from the lung
Right Atrium receives blood from the Vena Cava
Left & Right Ventricle
Right Ventricle Pushes blood out to the lungs
Left Ventricle Pushes out blood from the heart through the aorta
Layers of the heart
2.Myocardium
Endocardium
Epicardium
Vena Cava
Superior
Returns blood from head and arms to heart
Inferior
Returns blood from trunk and legs to heart
Major Arteries
Right coronary artery
Main blood vessels that supply blood to the heart
Left main coronary artery
Left anterior artery
The artery gives a lot of blood towards the front of the heart
Left circumflex artery
Supplies majority of the left atrium's blood
Blood Flow Process
oxygen poor blood enters right atrium
Oxygen poor blood in right atrium flow through the tricuspid valve
Oxygen poor blood enters the right ventricle
The oxygen poor blood goes from the right ventricle to the pulmonary valve
Oxygen poor blood enters lungs
Oxygen rich blood from lungs enters left atrium from pulmonary vein
Oxygen blood goes from the left atrium and through the mitral valve
Oxygen rich blood enters left ventricle

Major Veins
pulmonary vein
Returns now oxygenated blood (from lungs) to the heart
inferior vena cava
Carries deoxygenated to the lower portion of the body
basilic vein
Large superficial vein in the inner surface. Helps form the axillary vein
subclavian artery
Main artery of the lower limb
Differences between blood vessels

Disorders of the Cardiovascular system
Anemia
caused by a low supply of red blood cells
Leukemia
caused by excess amount of white blood cells
