- - - - Peripheral resistance is the resistance of the arteries to blood flow
  - - - The right atrioventricular valve is the tricuspid valve. The left atrioventricular valve is the bicuspid, or mitral, valve.
      - Papillary muscles attach to the leaflets of the tricuspid valve and bicuspid (mitral) valve via string-like tendons called the chordae tendineae.
        
        The heart’s papillary muscles serve the important purpose of shutting the heart valves tightly and prevent prolapsing of the valve leaflets every time that the heart beats, keeping blood from flowing back into the atrial chambers.
    - - The valve between the right ventricle and pulmonary trunk is the pulmonary semilunar valve. The valve between the left ventricle and the aorta is the aortic semilunar valve.
    - - Abnormal heart sounds are called murmurs.
  - - - Afterload is is the amount of resistance the heart must overcome to open the aortic valve and push the blood volume out into the systemic circulation.
