Using the information provided as you scroll overt the heart structures to complete the following table either on paper or on your blog:

Heart Anatomy Structures

STRUCTURE	FUNCTION	DEOXY/OXY BLOOD
LEFT ATRIUM	Chambers that receive blood returning from your body through your veins	OXY
LEFT VENTRICLE	Chambers where blood is pumped to your body through your arteries	OXY
RIGHT ATRIUM	Chambers that receive blood returning from your body through your veins	DEOXY
RIGHT VENTRICLE	Chambers where blood is pumped to your body through your arteries	DEOXY
PULMONARY ARTERY	Carries de-oxygenated blood from the right ventricle to the lungs	DEOXY
AORTA	Carries oxygen-rich blood from your heat to your body	OXY
PULMONARY VEINS	Carries oxygenated blood	OXY
SUPERIOR VENA CAVA	Returns blood to the heart through the veins coming from the head	DEOXY
INFERIOR VENA CAVA	Returns blood to the heart through the veins coming from the lower body	DEOXY
ATRIOVENTRICULAR VALVES (Mitral & Tricuspid)	Controls the flow oxygen-rich blood from your left atrium to you left ventrical; Controls blood flow from the right atrium to the right ventricle.	Mitral - OXY Tricuspid - DEOXY
CHORDAE TENDINAE	Connects the papillary muscles to the tricuspid valve and the mitral valve in the heart.	DEOXY
SEMI LUNAR VALVES (Pulmonary & Aortic)	Controls blood flow from the right ventricle through the pulmonary artery into your lungs; Controls blood flow from your left ventricle to your aorta.	OXY
SEPTUM	A wall of muscle separating the right and left side of the heart.	N/A

You will have to look up the structure and functions of the Chordae Tendinae elsewhere...

Now find a good heart diagram with all of the above structures labelled and post it to your blog.

Using the following link, describe the structure and function of the CORONARY ARTERIES AND VEINS.  What are they and what do they do?

• Coronary arteries branch off into smaller arteries, which supply oxygen-rich blood to the entire heart muscle.
