It has to get oxygen and get rid of CO2
in a fetus blood does not reach the lungs for purification. In a baby blood goes to the lungs for oxygenation.

It is not necessary for large quantities of blood to enter the pulmonary system of a fetus because the fetus receives oxygen and nutrients from the placenta, not through the lungs. The fetal lungs are collapsed and non-functional until after birth, so only a small amount of blood, needed for lung development, circulates through the fetal pulmonary system. The majority of blood is shunted away from the lungs through special fetal circulation pathways, allowing blood to bypass the lungs and flow directly to the rest of the body.
a fetus doesnt require much oxygen in the lungs as it isn't in the air and isn't being breathed in. a fetus aquires oxygen through other processes
no, it doesn't, but oxygen does.
The lungs, I the alviolies.
The lungs of the mother breath in the air. The lungs put the oxygen in the red blood cells. The blood flows through the walls of the uterus and through the umbilical cord into the blood stream of the fetus. The venus blood supply returns through a vein in the cord back into the mother and the lungs and the cycle repeats until the cord is cut.
lungs
That is very good question! You get the oxygenated blood from the placenta via umbilical vein in case of the fetus. This vein enters the liver of the fetus. The blood then goes to right atrium of the fetus. The lungs are closed in the fetus. So the blood goes to left atrium through foramen ovale to bypass the pulmonary circulation of the fetus. After the birth of the baby, baby takes the first breath. The lungs get inflated. Blood starts to flow via lungs. This closes the foramen ovale. The marking remains there on the wall between both the atria.
To make the lungs work and if our lungs didn't work then we couldn't breathe.
Yes, the blood enters the lungs via pulmunery artery
