Text-Fig.1. Semischematic drawings of the interior of the heart to show the steps in its partitioning

(From Embryology, Patten, B. M., courtesy P. Blakiston’s Son and Co.)

A. The cardiac septa are represented at the stage reached in human embryos early in the 5th week of development. Note especially the primary relations of interatrial septum primum. Based on original reconstructions of the heart of a 3.7 mm pig embryo, and on Tandler’s reconstructions of corresponding stages of the human heart.


B. The cardiac septa as they appear in human embryos of the 6th week. Note the restriction of interatrial foramen primum by the growth of interatrial septum primum. Based on original reconstructions of the heart of a 6 mm pig embryo, on Born’s reconstructions of the rabbit heart, and Tandler’s reconstructions of corresponding stages of the human heart.
