"Look at those lungs! Now in major growth mode, these late-blooming organs are crucial for baby's first real breaths after it exits the womb. (Baby's taking practice breaths in there every day -- so cute! -- but still gets all of the oxygen from the placenta.)"

"Turn on the radio and sway to the music. With a sense of movement well developed by now, your baby can feel you dance. And now that it's more than 11 inches long and weighs just over a pound (about as much as a large mango), you may be able to see it squirm underneath your clothes. Blood vessels in the lungs are developing to prepare for breathing, and the sounds that your baby's increasingly keen ears pick up are preparing baby for entry into the outside world. Loud noises that become familiar now — such as your dog barking or the roar of the vacuum cleaner — probably won't faze baby when it hears them outside the womb." - Baby Center
It was really weird to see my stomach roll all the way across for the first time. I was sitting at my computer and working on some business things when I caught it out of the corner of my eyes. I stopped and stared at my tummy and developing baby in there to try to catch it again. It is so amazing to see.
