While in the womb the baby gets everything it needs from the mother through the umbilical cord.
The mother's blood brings digested food and oxygen to the placenta. Here her blood vessels split up into capillaries and the food and oxygen diffuse across into the baby's blood capillaries, which join together to make the umbilical vein, which goes through the umbilical cord to the baby. In some ways, the mother provides the baby with what it needs in the same way as she does any part of her own body.
The baby receives oxygen from the red blood cells which are carried through the placenta from the mother to the child. The un-oxygenated blood cells then return to the mother where they go back to the heart and lungs to receive more oxygen.
Baby gets food and oxygen through the umbilical cord. This umbilical cord is attached to the placenta. This placenta is attached to the uterus. In the placenta blood of the mother comes close to the blood of the fetus. There is transfer of food and oxygen to the blood of fetus from the blood of mother. Carbon bi oxide and waste products of metabolism are transferred to the blood of mother from the blood of fetus.
The umbilical cord connects the mother and child. The baby gets oxygen from the mother's blood.
During a contraction, the flow of oxygen (from the mother) through the placenta (to the baby) is temporarily stopped
The developing baby (the fetus) gets its nutrition and oxygen from the mother through the umbilical chord; this chord is connected to the baby in the place of the belly button, where the nutrition enters the baby's intestines so that it is absorbed into their blood. The other end is attached to the placenta; it transfers all the nutrition and oxygen the baby needs from the mother.
Oxygen and nutrition goes to baby from mother. Carbon bi oxide and waste products of metabolism goes to mother from baby.
oxygen
Passes through their lunges
it passes oxygen and nutrients
During pregnancy carbon dioxide passes from the mothers blood to the baby's blood because the mother breathes the carbon dioxide in. It then travels around the body (Respiration) and the mother just replaces it with oxygen like normal. I think this is right and hope its helps :)
A developing baby gets its oxygen from the blood traveling through the umbilical cord.
