Week 9: "Grape"

[Bebito] is nearly an inch long — about the size of a grape — and weighs just a fraction of an ounce. He/she is starting to look more and more human. [Bebito's] essential body parts are accounted for, though they'll go through plenty of fine-tuning in the coming months. Other changes abound: [Bebito's] heart finishes dividing into four chambers, and the valves start to form — as do his/her tiny teeth. The embryonic "tail" is completely gone. [Bebito's] organs, muscles, and nerves are kicking into gear. The external sex organs are there but won't be distinguishable as male or female for another few weeks. [Bebito's] eyes are fully formed, but his/her eyelids are fused shut and won't open until 27 weeks. [Bebito] has tiny earlobes, and his/her mouth, nose, and nostrils are more distinct. The placenta is developed enough now to take over most of the critical job of producing hormones. Now that [Bebito's] basic physiology is in place, he/she is poised for rapid weight gain.
