The Circulatory Systm
4 Chambers
• The Human heart is a 4 Chambered heart
• It consists of two atriums and two
ventricles
• Atriums receive blood while Ventricles
pump it out to some part of the body
• Arteries carry blood away from the heart
while veins carry blood too the heart
Right Atrium
• The right Atrium receives blood from the
whole body except the lungs.
• The Superior and Inferior Vena Cava carry
the deoxygenated blood to this chamber.
• The blood is then moved to the Right
Ventricle.
Right Ventricle
• Receives deoxygenated blood from the
Right Atrium.
• Then it pumps this blood away from the
heart and to the lungs. At the lung the
blood will take up oxygen.
• Blood is carried away from the Right
Ventricle by the Pulmonary Artery.
Lungs
• When blood is carried to the lungs by the
Pulmonary Artery it goes through
narrowing passage.
• By the time the Blood gets to where it is
oxygenated in the lungs the passage is so
small only one blood cell at a time can fit
through it.
• It is then oxygenated and carried back to
the heart via the pulmonary veins.
Left Atrium
• The left Atrium receives blood from only
the lungs.
• The Pulmonary Veins carry the blood to
the Left Atrium
• This blood is oxygenated.
• The blood is then moved to the Left
Ventricle.
Left Ventricle
• Receives oxygenated blood from the Left
Atrium.
• Then it pumps this blood away from the
heart and to the whole Body except the
lungs.
• Blood is carried away from the Left
Ventricle by the Aorta.
