Chambers and Valves
The interior of the heart is divided into four chambers:upper right and left atria and lower right and left ventricles.The atria contract and empty simultaneously into the ventricles,which also contract in unison.The walls of the atria are reinforced with latticelike pestinate muscles.Contraction of these modified cardiac muscles ejects blood from the atria to the ventricles.Each atrium has an ear-shaped,expandable appendage called an auricle.The atria are separated from each other by the thin,muscular interatrial septum; the ventricles are separated from each other by the thick,muscular interventricular septum.Atrioventricular valves (AV valves) lie between the atria and ventricles,and semilunar valves are located at the bases of the two large vessels leaving the heart.Heart valves maintain a one-way flow of blood.
