BMC Dev Biol Search: Heart Development
Illustration of normal pericardial development from the fourth to sixth week of gestation. (a) At 4 weeks of gestation, the laterally positioned pleuropericardial folds are developed. (b) During the 5th week of gestation, the pleuropericardial folds grow toward the midline while the root of each fold migrates ventrally. (c) At the end of the 5th week, the pleuropericardial folds fuse, partitioning the thoracic cavity into a pericardial cavity and two partially formed pleural cavities. Note that union of the pleuropericardial folds and the root of the lungs also occurs during this time. (d) The lungs continue to extend anteriorly to the front of the heart.
