Heart Anatomy

STRUCTURE	FUNCTION	DEOXY/OXY BLOOD
LEFT ATRIUM	Collects oxygen-rich blood coming from  the lungs.  Then sends it to Left Ventricle	Oxy
LEFT VENTRICLE	Sends the blood aortic value and throughout the body	Oxy
RIGHT ATRIUM	Collects oxygen-poor blood coming back from the body and into the right ventricle	Deoxy
RIGHT VENTRICLE	Collects oxygen-poor blood from the right atrium and sends it through the pulmonary valve to the lungs	Deoxy
PULMONARY ARTERY	Carries blood from the hurt to the lungs to collect oxygen	Deoxy
AORTA	Carries oxygen-rich blood from the heart to the rest of the body	Oxy
PULMONARY VEINS	Carries oxygen-rich blood from the lungs back to the body	Oxy
SUPERIOR VENA CAVA	Oxygen-poor blood from the upper body returns to the heart	Deoxy
INFERIOR VENA CAVA	Oxygen-poor blood from the lower part of the body returns to the heart through here	Deoxy
ATRIOVENTRICULAR VALVES (Mitral & Tricuspid)	Carries blood from the atrium to the ventricle	Both
CHORDAE TENDINAE	Makes sure that the valves are shut so the blood keeps going forward and not backward	Neither
SEMI LUNAR VALVES (Pulmonary & Aortic)	Controls blood flow from right ventricle into pulmonary arteries and left ventricle to the aorta	Both
SEPTUM	Separates the right/left atrium and the right/left ventricle	Neither
