Pregnancy - Week 28

Email Print

The capillaries fully irrigate your baby's lungs now, although they're still developing. A substance called surfactant, is produced in order to keep his lungs tissues and air sacks from sticking together. The bronchial tubes are continually developing more and more branches inside the lungs tissues.

Your baby is over 1 Kg in weight now (2.2 lbs) and around 40 cm long (16 inches).
