Fetal heart embryology
TīmeklisEmbryogenesis, the first eight weeks of development after fertilization, is an incredibly complicated process. It’s amazing that in eight weeks we’re transforming from a single cell to an organism with a multi-level body plan. The circulatory, excretory, and neurologic systems all begin to develop during this stage.

Formation of the fetal heart begins at around the 23–25th day of gestation when the embryo is 2 mm long and it is completed when the embryonic length is 15 mm, at approximately day 46 of gestation. Some structures, such as the atrioventricular septum, complete their development later in pregnancy.
