HEART Made of cardiac muscle Made of cardiac muscle –a. Right atrium – receives blood from whole body –b. Left atrium  Receives blood from lungs –c. Right ventricle –  pumps blood to lungs –d. Left ventricle  Pumps blood to the body

Heart Valves – one way and separate the atrium from ventricle to prevent blood backflow Valves – one way and separate the atrium from ventricle to prevent blood backflow The wall separates the two sides of the heart to prevent OXYGENATED blood from mixing with deoxygenated blood. The wall separates the two sides of the heart to prevent OXYGENATED blood from mixing with deoxygenated blood

Types of Circulation Coronary – to and from the heart Coronary – to and from the heart Pulmonary – to and from lungs Pulmonary – to and from lungs Systemic – to and from the body Systemic – to and from the body

Blood vessels Artery – takes blood away from heart (red) Artery – takes blood away from heart (red) Vein – takes blood to the heart. (blue) Vein – takes blood to the heart. (blue) Capillaries – microscopic vessels where arteries and veins meet (purple) Capillaries – microscopic vessels where arteries and veins meet (purple)
