STRUCTURE

FUNCTION
|
DEOXY/OXY BLOOD
|
LEFT ATRIUM
|
- collects oxygen-rich blood returning from the lungs
-forces it through the mitral valve and into the left ventricle
|
oxy
|
LEFT VENTRICLE
|
- largest and strongest chamber in the heart
- wall is only 1/2 inch thick
- has enough force to push blood through the aortic valve and into your body
|
oxy
|
RIGHT ATRIUM
|
- collects oxygen-poor blood returning from the body
-forces it through the tricuspid valve and into the right ventricle
|
deoxy
|
RIGHT VENTRICLE
|
- collects oxygen-poor blood returning from the right atrium
-forces it through the pulmonary valve and into the lungs
|
deoxy
|
PULMONARY ARTERY
|
-carry blood from heart to lungs and picks up oxygen
|
deoxy
|
AORTA
|
-largest artery
- carries oxgen-rich blood from heart to entire body
|
oxy
|
PULMONARY VEINS
|
-carry oxygen-rich blood from lungs to heart
|
oxy
|
SUPERIOR VENA CAVA
|
-oxygen-poor blood from the upper parts of the body returns to the heart through the superior vena cave
|
deoxy
|
INFERIOR VENA CAVA
|
-oxygen-poor blood from the lower parts of the body returns to the heart through the superior vena cave
|
deoxy
|
ATRIOVENTRICULAR VALVES (Mitral & Tricuspid)
|
-tricuspid controls blood flow from the right atrium to the right ventricle
-mitral controls flow from the left atrium to the left ventricle
|
deoxy/oxy
|
CHORDAE TENDINAE
|
- bring right ventricular walls closer together during contraction
-pull the AV Valves open during atriole systole
|
left oxy
right deoxy
|
SEMI LUNAR VALVES (Pulmonary & Aortic)
|
-pulmonary valve control blood flow from right ventricle to the pulmonary arteries
- aortic valve controls blood from left ventricle to aorta
|
deoxy/oxy
|
SEPTUM
|
sperates left from right
|
-Coronary arteries and veins are the blood vessels that supply blood and carry blood away from the heart muscle. The left coronary arteries supply blood mainly to the left side of the heart and vice versa.
