Structures of the Heart
Slide2Chambers
Your heart is divided into 4 chambers:
Right and Left Atria
Right and Left Ventricles
Slide3Right Atrium
Receives de-oxygenated blood from superior vena cava (head and upper body) and inferior vena cava (legs and lower torso).
Contains pacemaker cells in a place called the
s
inoatrial
node
----This node sends electrical signals to the right
a
trium causing it to contract pushing blood to right ventricle.
Slide4Right Ventricle
Receives de-oxygenated blood from right atrium----Once filled it pumps blood into pulmonary artery.
Receives electrical signal from group of pacemaker cells located in the
atrioventricular
node
causing it to contract.
Slide5Left Atrium
Receives oxygenated blood from lungs through the pulmonary veins.
Once filled it contracts due to electrical signal from the
sinoatrial
node.
Slide6Left Ventricle
Receives oxygenated blood from left atrium----Once filled it pumps blood into aorta and out to the rest of the body.
Receives electrical signal from group of pacemaker cells located in the
atrioventricular
node
causing it to contract.
