  • Auricle 2 in number at broad area.
  • Both are small, flap like cover ventricles like caps i.e. auricular appendix. It's skeleton is made up of musculo-pelati.
  • Ventricles 2, large at apex area.
  • Left ventricle is comparatively large and covers complete apex.
  • Right ventricle does not reach the apex.
  • Both ventricles are separated by a groove ventricular sulcus externally here caronary artery present that supply blood to complete heart.
  • Auricles are demarkated externally from ventricle by coronary sulcus.
  • 1 pre caval and 1 post caval open in right auricles. (In cat pre cavals are absent) In rabbit 2 pre cavals present.
  • In L.A. 2 pairs pulmonary veins open. (In rabbit one pair)
