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)
In broad area left carotico systemic arch and pulmonary aorta (total 3) present.
All veins open in auricles. All arteries originate from ventricles.
