Internal structure of the heart of man
  1. Internally there are four chambers in the heart. The upper two chambers are called auricles and the lower two chambers are called ventricles.
  2. Right and left auricles are separated by inter auricular septum which prevents the mixing of deoxygenated blood in the right auricle with oxygenated blood in the left auricle.
  3. Similarly right and left ventricles are separated by inter ventricular septum, which also prevents the mixing of blood in the ventricles.
  4. Auricles and ventricles are separated by auriculo-ventricular septum, which prevents the mixing of blood in between auricles and ventricles.
  5. The walls of ventricles are thicker and muscular than those of auricles.
  6. The left ventricle pumps the blood to more distant parts of the body like fingers and toes.
  7. The right ventricle pumps blood to lungs.
  8. There are two openings in the auriculo-ventricular septum through which right auricle opens into right ventricle and left auricle opens into left ventricle. These openings are guarded by tricuspid and bicuspid valves respectively.
