Fetuses need oxygen because (like us) they are made up of cells that use aerobic metabolism. Aerobic metabolism is a system used by cells to make cellular energy out of glucose (sugar) and Oxygen. Fetuses, which start out as one unique cell, need oxygen because they have the same machinery.
If for some reason they didn't get enough oxygen they (like us) would start producing acid and 1/16th of the energy they were producing before and the cells would die.

They don't. They're hooke on to the mother's blood supply through the umbilical cord and the placenta, and get their oxygen from her.

∙ 8y agoIt is a beautiful question! The foetus does not take a single breath in the womb of the mother. Still it gets oxygen. Carbon bi oxide is carried away. It gets the nutrition. the waste products of metabolism are carried away. The nature has got a very special technique for the same. You have the placenta in the uterus. In the placenta the blood from the mother comes and goes. The blood from the foetus also comes and goes in the placenta. Blood from both of them come very close to each other. But there is no mixing. Very thin membrane keep them separated. The placenta has got very large surface area to perform this miracle. The exchange of gases and nutrition and waste products takes place in fraction of second. The oxygen and products of nutrition are given at the proximal end of the capillaries. The carbon bi oxide and waste products of nutrition are taken away at the distal end of the capillaries.

How does a developing human fetus obtain its nourishment and oxygen?
Umbilical cord
How does the fetus obtain food and oxygen?
The mother's blood supply enters the foetus via the umbillical cord and allows oxygen to diffuse from the mother's blood into the foetus.
What takes nutrients and oxygen to the fetus?
The umbilical cord takes nutrients and oxygen to the fetus.
How does air oxygen enter the mother to feed foetus?
Through the umbilical cord from the placenta since a fetus can't use lungs to obtain oxygen. Read more in the link below about fetal circulation.
Is the function of the umbilical cord to let oxygen into the fetus?
The umbilical cord delivers oxygen and nutrients to the fetus and removes wastes.
How is the circulation of a different from the circulation of a baby?
in a fetus blood does not reach the lungs for purification. In a baby blood goes to the lungs for oxygenation.
What organ serve as respiratory organ for the fetus?
The umbilical cord supplies the fetus' oxygen.
How does your body obtain oxygen?
Our body obtain oxygen to our body by breathing.
Can the fetus metabolize glucose without oxygen?
First of all, the human fetus does have oxygen. The oxygen is obtained from the mother's blood via the placenta. But if the fetus did not have oxygen temporarily, s/he could still metabolize glucose. This would be done the same way that other humans metabolize glucose without oxygen--by converting it to lactic acid.
How nutrients oxygen and waste are exchanged between the fetus and the mother?
how nutrients,oxygen and waste are exchange between the fetus and the mother
What passes through the fetus to the placenta?
oxygen and nutrition
How does the fetus get its oxygen?
From the mother's blood via the placenta.
