Little man is growing by leaps and bounds! He's developing a firm grasp and may reach out and grab the umbilical cord. He can also stick out his tongue!
Under his skin, capillaries are forming and filling with blood and by week's end, air sacs (also lined with capillaries) will develop in his lungs, getting them ready for that first breath. Those lungs aren't ready for prime time just yet - but they are developing surfactant, a substance that will help them expand after birth. Speaking of breathing…
baby's tiny little nostrils, which have been plugged up until now, are starting to open, and his vocal chords are getting ready to roar!
