On the assumption that different parts of the original tube underwent development at different rates, the auricles and ventricles of the adult heart could be viewed as highly developed cavities which had bulged out from the original tube, while the remnant of that tube could be recognized in the undeveloped fibers of the sinus, the sinoauricular ring, the auricular partition, and the auriculo-ventricular ring.
