Uteris
The female organ that a developing baby grows in is the uterus.
It is called a "uterus".
It's called the uterus, this is also where the baby grows at, this is why it expands since when the baby grows it needs more room.
The uterus is the organ in which babies grow. vs. Food get digested in the stomach.
Though children learn to call the entire belly the "stomach", the whole belly is technically called the abdomen. The organ, stomach, is in the top of the abdomen near your ribs. A baby grows in the organ, the uterus. The uterus is in the lowest part of the abdomen, near your pubic bone. The uterus is sort of like a balloon; as the baby grows, the uterus expands upward, toward the organ the stomach.
A baby isn't made in a stomach, It is conceived in the womb, and grows in there, via cell reproduction.
I'm going to assume you mean 'placenta'. It is the organ that grows along with the baby in the uterus and is attached to the uterus and the baby, via the navel, providing nourishment to the baby during gestation. It is delivered after the baby at birth and the connection to the baby is severed.
