Breathing or respiration is the process of moving air into and out of the lungs to facilitate gaseous exchange. It is the mechanism by which oxygen enters the body, and carbon dioxide is expelled from the body. In other terms, breathing is important to sustain life and without respiration (natural or artificial), a human being can not survive for more than a few minutes. Babies do not take their first breath until after they are born. However, developing babies do need oxygen even in the womb.
So, how do babies breathe (or facilitate gaseous exchange) while in the womb?

Even after the baby’s lungs are developed in the womb, the baby is surrounded by amniotic fluid and hence even the lungs are filled with amniotic fluid. In the third trimester, babies do take practice breaths by filling the lungs with even more amniotic fluid, but it does not transfer oxygen into the baby’s body.
Since babies do not breathe until after birth, the oxygen requirement is met through the umbilical cord. After 5-6 weeks of pregnancy, the umbilical cord develops to directly deliver oxygen to the developing fetus. The umbilical cord is connected to the placenta and is responsible for delivering nutrients as well as oxygen-rich blood which is required for the baby’s growth in the womb.

Thus, the mother breathes in oxygen for the baby, which is transferred to the baby through the umbilical cord. Similarly, the carbon dioxide in the baby’s body is expelled out through the mother. The umbilical cord has two separate veins and hence the stuff going inside the baby never mixes with the one coming out.
