The early embryonic period is complete at the end of this week, and it is the start of the fetal period. The development of the embryo was characterized by the three cell lines each developing into their own types of tissues and organs, as it grew from a flat disk of cells into a human shape. Many of the changes took place concurrently, but it was the heart, circulation, and nervous systems that developed initially with the gut, limbs, and face development following.
During next week (your 11th week), your baby's kidneys and genital system will undergo their most rapid development. All your baby's organs need to mature fully, and many of them, such as the brain, lungs, and kidneys, will continue to mature throughout pregnancy and after birth.
During this ninth week, your baby's facial features are becoming more recognizable. The ears will take on their final shape, although they are still positioned low.
