The reason why a fetus does not drown in amniotic fluid is that instead of using its lungs to breathe, the fetus uses the umbilical cord to establish a connection with its mother and uses the oxygen in the blood to breathe. The placenta and umbilical cord supply the fetus with the oxygen and nutrients it needs as it grows in the mother’s womb. The placenta is the digestive, respiratory and excretory organ of the fetus. While the nutrition and oxygen needed by the fetus are supplied mainly through the umbilical cord, the waste produced can be metabolized through the umbilical cord and placenta. So the fetus does not need to take in oxygen and will not drown in the amniotic fluid. It is important to note that only after birth will the fetus be able to breathe through its lungs, so it is important to stay away from water sources after birth to avoid drowning. It is recommended to make sure you have regular checkups during your pregnancy, and also pay attention to rest, and seek medical attention if you feel any discomfort.
