how nutrients,oxygen and waste are exchange between the fetus and the mother
The placenta nourishes the fetus.
The umbilical cord
Mostly the placenta
The Placenta.

There are many substances they exchange, but the main ones are oxygen from the blood to the cells and CO2 from the cells to the blood.
oxygen.
The placenta is where the material between mother and child, like nutrients and oxygen, travel from one to another.
In the case of animals, these exchanges occur in the capillaries.
Arteries to arterioles to capillaries where exchange occurs. Oxygen and nutrients are exchanged for carbon dioxide and wastes.

A mammalian embryo gets oxygen and nutrients from it mother by means of the umbilical cord which extends the embryonic blood supply into the placenta embedded in the mothers womb. The blood supply in the placenta is close to that of the mother and oxygen and nutrients diffuse across from the mother to the baby. With egg laying animals the nutrients are supply to the embryo as the yolk part of the egg and oxygen is supplied by diffusion through the permeable shell and shell membrane
Plants give us oxygen we give them carbon dioxide.
The exchange occurs in the space between the cells in something called interstitial fluid. It literally means tissue fluid. It is what is between the capillaries that carry blood and lymph and the cell membrane through which the nutrients and waste have to pass.
