Fetal Weight Standard
Week 16 brings remarkable circulatory progress. The fetal cardiovascular system is pumping approximately 25 quarts of blood every single day through tiny vessels.
Coordinated eye movements begin beneath the fused eyelids. The legs are now longer than the arms, and the baby moves limbs with greater dexterity and force. Mothers who have had children before may begin noticing early flutters.
