22 Weeks....

The baby is approx 26 cm in length and weights 550 grams

The baby’s body continues to grow and develop every day. The organ systems in the baby's body are becoming specialized for their particular functions. The fetal liver produces different enzymes than it will produce after delivery. The liver is responsible for breaking down billirubin, which is produced by the breaking down of blood cells. Because the life span of a fetal red blood cell is shorter than that of an adult, a fetus produces more billirubin than adults do. Billirubin passes from fetal blood to the placenta and then into your blood. Your liver helps get rid of fetal billirubin. A newborn baby that has high levels of billirubin may show signs of jaundice. Jaundiced babies have a yellowish tint to their eyes and skin and are often treated with phototherapy.

The baby's senses are developing daily. The fetus now has a full complement of neurons in the brain and is learning about his body and surroundings through touch. Touch is one of the first senses to mature and the baby may stroke its face or feel his arms and legs.
