Heart Structure

STRUCTURE	FUNCTION	DEOXY/OXY BLOOD
LEFT ATRIUM	one of four chambers and pumps blood into the left ventricle	OXY BLOOD
LEFT VENTRICLE	The strongest and largest of all the chambers, the left ventricle has enough force to pump blood to tissues all over the body.	OXY BLOOD
RIGHT ATRIUM	The right side of the heart then pumps blood into the pulmonary veins around the lungs.	DEOXYGENATED BLOOD
RIGHT VENTRICLE	pumps the blood up through the pulmonary valve and through the pulmonary artery and to the lungs.	DEOXYGENATED BLOOD
PULMONARY ARTERY	the vessel transporting blood from the right ventricle to the lungs. vessels carry blood away from the heart.	DEOXYGENATED BLOOD
AORTA	largest artery in the body.  begins at the top of the left ventricle  The heart pumps blood from the left ventricle into the aorta through the aortic valve.	OXYGENATED BLOOD
PULMONARY VEINS	Carries oxygen, rich blood from lungs back to heart	OXYGENATED BLOOD
SUPERIOR VENA CAVA	Oxygen, poor blood from upper body returns to heart	DEOXYGENATED BLOOD
INFERIOR VENA CAVA	Oxygen, poor blood from lower body returns to heart	DEOXYGENATED BLOOD
ATRIOVENTRICULAR VALVES (Mitral & Tricuspid)	controls blood flow from atrium to ventricles	DEOXY /OXYGENATED BLOOD
CHORDAE TENDINAE	bring right ventricular walls closer, holds valves in place
SEMI LUNAR VALVES (Pulmonary & Aortic)	control blood flow from ventricles to aorta	DEOXY /OXYGENATED BLOOD
SEPTUM = seprates left and right atria and ventricles
