How do babies breathe inside the womb?

Answer 1

Oxygen is carried through the blood. The mothers blood flows to the baby and gives them oxygen from the mother. A baby doesn't take its first breath of air until it is born. That is why a mother shouldn't smoke while she is pregnant. It decreases the amount of oxygen to the baby.

Through the umbilical cord that's hooked to the mother's blood supply via the placenta.

Answer 2

Babies receive oxygenated blood from their mother through the umbilical cord until the moment of birth. At birth, the baby inhales air into the lungs for the first time, and oxygenation immediately switches from a blood-to-blood connection throught their mother to an air-to-blood process that the baby will use for the remainder of its life. Concurrent with this remarkable process, a duct (the ductus arteriosus) in the heart closes. While the duct is open, the neonate's blood bypasses the neonate's lungs since they are unused in the womb. At birth, the intra-heart ductus closes, and the blood is immediately shunted through the newly functioning lungs for oxygenation.

It should be noted that fetuses gestate in the uterus, not in the stomach.

Answer 3

A baby gets oxygen from the it mother from theplacenta also food goes through to the baby and the waste products eg. (carbon doxide) gets passed from the baby to the mother and is mixed in with the mothers waste products.

Answer 4

i dont know. when they did my ultrasound, i saw the babys tummy inflate and diflate==============================

Babies in the uterus (womb) don't breathe as we know it as they are enclosed in a sac of fluid. Their lungs "breathe" in this fluid and then "breathe" it out. They also swallow and excrete this fluid (amniotic fluid). You can see this on an ultrasound scan. When the baby passes through the birth canal (vagina) at delivery, the fluid is "squeezed" out and when the baby is born, they take a breath of air and normal breathing takes place. Sometimes the baby needs to have some left over fluid cleared from their nose and mouth after a normal (vaginal) delivery. They will always have their nose and mouth cleared by suction after a C Section as they don't have it squeezed out during delivery. Hope this helps.

Answer 5

No. There is no air in the womb. They obtain their oxygen through the umbilical cord. There is no air so the baby does not breath, but it does make breathing motions. no. it has oxygen, food and everything else it needs delivered through the cord. it starts breathing when it is born.

Answer 6

It does not breathe because his or her lungs are contained with fluids and are not involved with supplying oxygen to the body.
Babies don't breath while in the womb. They first get to use their lings when they are born, and start crying.

Answer 7

Babies don't have to know how to breathe -- it's all pre-programmed. When the carbon dioxide level in the blood gets to a critical level (remember the baby has been cut off from his mother's input), the brain will set several things in motion, ultimately resulting in the baby breathing air and exchanging oxygen for that carbon dioxide.

Answer 8

same as any baby they inhal then exhal just like anybody!!

Answer 9

Unborn babies breathe through the mothers umbiblical cord that is how they also breathe drink and excrete
