STRUCTURE	FUNCTION	DEOXY/OXY BLOOD
LEFT ATRIUM	Takes in oxygen-rich blood back into the heart from the lungs and forces it through the Mitral valve into the Left Ventricle.	Oxy Blood
LEFT VENTRICLE	Pushes the blood through the Aortic valve and out into your body.	Oxy Blood
RIGHT ATRIUM	Collects oxygen-poor blood coming back from the body and forces it through the Tricuspid valve and into the Right Ventricle.	Deoxy Blood
RIGHT VENTRICLE	Takes the oxygen-poor blood and forces it through the Pulmonary Valve into the lungs for oxygen.	Deoxy Blood
PULMONARY ARTERY	Carries blood from the heart to the lungs to pick up oxygen.	Deoxy Blood
AORTA	Carries oxygen-rich blood from the heart to the rest of your body.	Oxy Blood
PULMONARY VEINS	Carries oxygen-rich blood back from the lungs to the heart.	Oxy Blood
SUPERIOR VENA CAVA	Oxygen-poor blood returning from the upper parts of the body to the heart comes through the Superior Vena Cava.	Deoxy Blood
INFERIOR VENA CAVA	Oxygen-poor blood returning from the lower parts of the body to the heart comes through Inferior Vena Cava.	Deoxy Blood
ATRIOVENTRICULAR VALVES (Mitral & Tricuspid)	They both control blood flow from their respective atriums into their respective ventricles.	Mitral is Oxy Blood and Tricuspid is Deoxy Blood
CHORDAE TENDINAE	Relaxes when blood is flowing from the Atria to the Ventricles and pushes both AV Valves to close simultaneously preventing backflow into the Atria and the flaps attempt to evert to low pressure regions.	Oxy Blood on left side and Deoxy Blood on right side
SEMI LUNAR VALVES (Pulmonary & Aortic)	The Pulmonary Valve controls blood flow into the Pulmonary Arteries from the Right Ventricle and the Aortic Valve controls blood flow into the Aorta from the Left Ventricle.	Pulmonary is Deoxy Blood and Aortic is Oxy Blood
SEPTUM	Separates the Left and Right Atria and the Left and Right Ventricles.	Deoxy Blood and Oxy Blood
