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
|

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?

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.
