Construction is under way! Your developing embryo now has three layers: The first layer is the neural tube from which the brain, spinal cord and nerves, and backbone will sprout; the heart and the circulatory system are beginning to appear in the middle layer; and the third layer will house the lungs, intestines, and urinary system. In the meantime, the early version of the placenta, the chorionic villi, and the umbilical cord - which delivers nourishment and oxygen to your baby - are already on the job.
