Heart Flashcards
Atria (atrium) =
superior chambers of the heart, act as a reservoir
Ventricles =
inferior chambers of the heart
Arteries =
blood vessels that go away from the heart
Veins =
blood vessels that go toward the heart
Sinoatrial node (SA node) =
pacemaker of the heart
Left ventricle = delivers
delivers oxygenated blood to the rest of the body
Right atria = gathers
gathers deoxygenated blood from the body
Capillaries =
smallest blood vessels, site of exchange of elements between blood & tissue
“A comes before V in the alphabet”
This signifies that blood will first flow into the Atria on top, then down to the Ventricles to be pumped out to either the lungs or body.
“Right returns and left leaves”
This signifies that the right-side chambers collect returning deoxygenated blood from the body (right atrium) and send it to the lungs (right ventricle), while the left-side chambers collect oxygenated blood that has left the lungs (left atrium) and send it out to the body (left ventricle).
