The heart pumps deoxygenated blood to the lungs via the
pulmonary artery
heart pumps blood to the body via the
aorta
Right side of the heart is the
pulmonary circulation
left side of heart is the
systemic circulation
When the heart contracts
systole
when the heart relaxes
diastole
Venae Cavae
are large vessels that move deoxygenated blood to heart’s right upper chamber called atrium
atrium
heart’s right upper chamber
ventricle
heart’s right lower chamber
After the right atrium fills, it contracts and pumps blood into the
heart’s right lower chamber, called the ventricle.
When the right ventricle is full, it contracts and pumps blood through
the pulmonary artery into the lungs.
In the lungs, blood
picks up oxygen and discards carbon dioxide.
oxygenated blood flows from the lungs through the
pulmonary veins into the heart’s left atrium.
pulmonary veins
carries oxynated blood from lungs to heart’s left atrium
After the left atrium fills,
it contracts and pumps blood into the left ventricle.
When the left ventricle is full, it pumps blood through the
aorta—the body’s largest artery—for distribution to the rest of the body’s blood vessels.
valves
Veins have thin walls and use valves to control blood flow
