"Your embryo's heart, no bigger than a poppyseed, has already begun to beat and pump blood. The heart is dividing into chambers, and will find a more regular rhythm soon. The embryo itself is about a quarter inch long and looks more like a tadpole than a human. It undergoes a growth spurt this week.
Major organs, including the kidneys and liver, begin to grow. The neural tube, which connects the brain and spinal cord, will close this week. The embryo's upper and lower limb buds begin to sprout — these will form your baby's arms and legs. The intestines are developing and the appendix is in place.
Below the opening that will later form the mouth, small folds exist where the neck and the lower jaw eventually develop. As early as this week, facial features are already forming. Nostrils are becoming distinct, and the earliest version of the eyes' retinas are forming." -- BabyCenter.com
