Function
|
DEOXY/OXY BLOOD
|
|
LEFT ATRIUM
|
Pumps blood into the left ventricle
|
Receives oxygenated blood
|
|
LEFT VENTRICLE
|
Pumps blood to the whole body(tissue)
|
Oxygenated blood
|
|
RIGHT ATRIUM
|
Pumps blood into the right ventricle
|
Deoxygenated blood
|
|
RIGHT VENTRICLE
|
Pumps blood to the pulmonary valve to the
lungs
|
Deoxygenated blood
|
|
PULMONARY ARTERY
|
Transports deoxygenated blood from the
right ventricle to the lungs
|
Deoxygenated blood
|
|
AORTA
|
The heart’s largest muscular chamber. Pumps
blood from left ventricle to the aorta then the aortic valve
|
Oxygenated blood
|
|
PULMONARY VEINS
|
Carry blood from lungs to left atrium
|
Oxygenated blood
|
|
SUPERIOR VENA CAVA
|
One of the main two valves brings blood
to the heart from the upper part of body, empties into the right atrium
|
Deoxygenated blood
|
|
INFERIOR VENA CAVA
|
Carries blood from lower half of body to
right atrium of the heart
|
Deoxygenated blood
|
|
ATRIOVENTRICULAR VALVES
|
Separates the atria from the ventricles,
allows blood to flow from the atria to the ventricles prevents flow in
opposite direction
|
Both deoxygenated and oxygenated blood
|
|
CHORDAE TENDINAE
|
Protects the walls of the ventricles(
fibrous strings)
|
Both deoxygenated and oxygenated
|
|
SEMILUNAR VALVES
|
Controls the blood from moving back into
the ventricles
|
Both deoxygenated and oxygenated blood
|
|
SEPTUM
|
A wall of muscle that separates the left from the right of the heart
|
N/A

THE CORONARY ARTERIES AND VEINS
The aorta branches off into two coronary blood vessels (also called arteries). These coronary arteries branch off into smaller arteries, which supply oxygen-rich blood to the entire heart muscle.
The right coronary artery supplies blood mainly to the right side of the heart. The right side of the heart is smaller because it pumps blood only to the lungs.The left coronary artery branches into the left anterior descending artery and the circumflex 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.
