Heart chambers
Atriums – The chambers at the top of the heart
Ventricles - The chambers at the bottom of the heart
Picture a tree (atriums) growing out from the top of the heart, to remember atriums.
Picture the heart with vents trickling (ventricles) out steam from the bottom, to remember ventricles.
