How does a baby in the uterus get nourishment?

A baby in the uterus receives nourishment through the placenta. The placenta is an organ that forms in the uterus during pregnancy and is connected to the umbilical cord. The umbilical cord is a long, thin tube that carries blood from the baby to the placenta and back again.

The placenta allows oxygen and nutrients from the mother's blood to pass into the baby's blood. It also allows waste products from the baby's blood to pass into the mother's blood. This exchange of oxygen, nutrients, and waste products is essential for the baby's growth and development.

The placenta also produces hormones that help to maintain the pregnancy. These hormones include progesterone, estrogen, and human chorionic gonadotropin (hCG).

The placenta is a vital organ for the growth and development of a baby in the uterus. It provides the baby with oxygen, nutrients, and hormones, and it removes waste products from the baby's blood.
