Development of your baby
The previous week saw your baby show the start of the facial features developing. This week, the facial features get more distinct. Also the hands and legs start to protrude out even more. The vital organs like the kidneys, liver, heart, intestine, pancreas and the appendix have developed at an exponential pace, and now your baby's digestive system is almost formed.
Soon the kidneys will start to do their function too, mostly by the end of the week and the newly formed liver has already started to churn out red blood cells. The developing pancreas will start to produce insulin that would aid digestion.
The teeth and tongue also starts to form inside the mouth though they aren't visible yet. Your baby now has its own blood type too.
By week seven your baby's whole skeletal system is in place. But technically your baby is still an embryo measuring somewhere up to 13mm. By now the placenta develops to keep the baby safe and sound inside the womb along with minute hair-like projections called the villi which help in the nutrition and nourishment exchange between the mother and the baby. Also the umbilical cord shows its presence which now has distinct blood vessels and helps in oxygen and nutrition exchange for the baby through the placenta.
