FUNCTION
|
DEOXY/OXY BLOOD
|
LEFT ATRIUM
|
Pumps blood into the left ventricle
|
receives oxygenated blood
|
LEFT VENTRICLE
|
pumps / releases blood into into the whole body ( into tissues)
|
oxygenated blood
|
RIGHT ATRIUM
|
pumps blood into the right ventricle
|
dexygenated blood
|
RIGHT VENTRICLE
|
pumps blood to pulmonary valve and then pulmonary artery and then lungs.
|
de-oxygenated blood
|
PULMONARY ARTERY
|
Pumps de-oxygenated blood from right ventricle to the lungs
|
de- oxygenated
|
AORTA
|
used as a chamber to pump blood to the aortic valve
|
oxygenated
|
PULMONARY VEINS
|
carries oxygenated blood from the lungs to the left atrium of the heart.
|
oxygenated
|
SUPERIOR VENA CAVA
|
brings deoigenated blood from the upper part of the body to the hear t
|
d-eoxygenated
|
INFERIOR VENA CAVA
|
brings deoxognated blood from the lower part of the body and brings it to the right atrium
|
de-oxygenated
|
ATRIOVENTRICULAR VALVES (Mitral & Tricuspid)
|
separates the atria ventricles , allows blood to flow from the atria to the ventricles and prevents flow in the opposite direction
|
Both
|
CHORDAE TENDINAE
|
protects the walls of the ventricles ( fiber strings)
|
both
|
SEMI LUNAR VALVES (Pulmonary & Aortic)
|
control the blood from moving back into the ventricle
|
both
|
SEPTUM
|
sepetates the left atrium and ventrivle mixing with the rest.

The Coronary Arteries
The aorta is the largest artery. Its purpose is serve as the main supplier of oxygenated blood. It breaks into two small branches the right coronary artery and the left , they are used so for the heart muscle. ( the heart needs blood too!) The right coronary artery supplies blood mainly to the right side of the heart and is usually smaller because the blood pumps only to the lungs.( a much smaller trip)
heart, following that the The left coronary artery supplies blood to the left side of the heart. The left side of the heart is larger and more muscular because it pumps blood to the rest of the body. ( it takes alot more effort.
