According to babiesonline.com:
Your baby's body systems are starting to work on their own. The digestive system practices moving food along the intestines and through the renal system and he can create and eliminate urine. He also continues to practice breathing the amniotic fluid in and out of his lungs. Your baby has tiny, soft nails on his fingers and toes, is growing hair and may even suck his thumb. Your baby is approximately 10-11.5 cm (3 ½ -4 inches) and weighs approximately 1.5 ounces.
Also, your baby's blood is beginning to form in the bone marrow and blood vessels are beginning to connect various parts of the fetus to another. The joints and muscles allow your baby full body movement so your baby is able to move around. The baby's neck is getting longer and his chin is no longer resting on his chest. The eyes and ears continue to move into place. The hands are becoming functional and reflex movements often occur. Nourishment now comes from the placenta.
