Does carbon dioxide pass through the mothers blood or the baby's blood?

Carbon dioxide travels through both their bloods. All the cells of the baby and of the mother respire and produce carbon dioxide, which diffuses into the blood and circulates with it. In the mother, it eventually reaches her lungs where it diffuses into the alveoli and is breathed out. The baby has no functioning lungs, so when carbon dioxide rich blood travels through the umbilicus to the placenta, the carbon dioxide diffuses across to the mother's blood vessels, whence it proceeds to her lungs as before.

What is passed through umbilical cord?
The growing baby has wastes and needs oxygen and nutirnets through out its time in the womb... The placenta holds many tiny cappilaries( very small blood vessels) Half are babies, and half are moms. These blood vessels run very close to each other.. The oxygen and nutrients that the baby needs are diffused from the mothers cappilaries to the babys cappilaries. In other words the oxygen and nutrients in the mothers blood is passed to the babys blood with out touching, the tiny particles are small enough to go through the walls of the cappilaries. These much needed nutrients are then taken to the baby through the imbilical cord. The baby also makes many waste products, carbon dioxide, urea(what makes up most of urine), extreme amounts of water, and salt are a few.. These waste go through the imbilical cord, to the babies tiny cappilaries in the placenta. Then it diffuses into the mothers cappilaries in the placenta.. The mother then gets rid of these waste products.
