An artificial uterus is like a big machine or container which works like a real uterus. It's made up of a few different things like a nutrient solution that keeps the baby safe and healthy while it grows, and a pouch that keeps the baby warm and protected from the outside world. Inside this pouch, the baby grows as if it were in a mother's womb. This machine helps doctors care for babies born too early, or babies whose mothers are not able to carry them in their own wombs. It is a very special machine that helps babies grow and stay healthy until they are ready to be born.
