The mother is the "host" for the fetus until birth. All nutrition and growth support is done by virtue of the mother's umbilical cord. IT provides all oxygen and nutrition while connected.
Oxygen is delivered from the mother's bloodstream across the placenta to the fetus by diffusion. The oxygen molecules move from an area of high concentration in the mother's blood to an area of low concentration in the fetal blood, allowing oxygen to reach the cells of the fetus for respiration.

What organ provides oxygen to cells?
The lungs provide oxygen to cells by extracting oxygen from the air we breathe and delivering it to the blood. The blood then carries the oxygen to all cells in the body.
How can you get the oxygen you need?
You can get the oxygen you need by breathing in air. The air you breathe contains oxygen that is absorbed by your lungs and then transported by your red blood cells to all the cells in your body. Adequate ventilation, good lung function, and clean air are essential for ensuring you receive enough oxygen.
What organ or structure absorbs oxygen from air?
The respiratory system seems like the obvious answer, but you used the word absorb. The respiratory system takes air into the lungs, but the red blood cells (erythrocytes) absorb the oxygen out of the air taken into the lungs. The circulatory system then delivers these red blood cells to the capillaries where the oxygen is traded for carbon dioxide as the cells need.
Why does the fetus needs calcium and iron?
Calcium is essential for developing strong bones and teeth in the fetus, as well as for proper muscle and nerve function. Iron is necessary for the production of hemoglobin, which carries oxygen to all cells in the body, including the fetus. Both nutrients are crucial for the overall growth and development of the fetus during pregnancy.
How does oxygen get to the cells in respiration?
Oxygen is carried to the cells in the body by red blood cells through the bloodstream. The respiratory system, specifically the lungs, absorbs oxygen from the air during inhalation, which is then transported to the cells where it is used for cellular respiration to produce energy.
Describe how oxygen gets from the air to the cells of the foetus?
Oxygen from the mother's blood diffuses across the placenta into the foetal blood. This oxygen is then carried by red blood cells to the cells of the foetus through the circulatory system. The exchange of oxygen and carbon dioxide occurs at the capillaries, allowing oxygen to reach the foetal cells for cellular respiration.
What do organisms do with the oxygen they absorb from the air?
Organisms use the oxygen they absorb from the air for their cells. The cells need this oxygen in order to carry out their functions.
Why is is not necessary for large quantitites of blood to enter the pulminonary system of a fetus?
Oxygen is supplied by the mother since the fetus has no air to breathe.
What organ provides oxygen to cells?
The lungs provide oxygen to cells by extracting oxygen from the air we breathe and delivering it to the blood. The blood then carries the oxygen to all cells in the body.
What organ serves as a respiratory organ for the fetus?
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.
What takes nutrients and oxygen to the fetus?
The umbilical cord takes nutrients and oxygen to the fetus.
What do the air vessels in the lungs send to the cells by way of blood vessels?
The air sacs send oxygen to the cells.
What organ absorbs oxygen from the air?
The respiratory system seems like the obvious answer, but you used the word absorb. The respiratory system takes air into the lungs, but the red blood cells (erythrocytes) absorb the oxygen out of the air taken into the lungs. The circulatory system then delivers these red blood cells to the capillaries where the oxygen is traded for carbon dioxide as the cells need.
Where is oxygen when you breathe in?
Oxygen is in the air, and when you breathe in the oxygen gets into your lungs and is absorbed into the red blood cells.
How can you get the oxygen you need?
You can get the oxygen you need by breathing in air. The air you breathe contains oxygen that is absorbed by your lungs and then transported by your red blood cells to all the cells in your body. Adequate ventilation, good lung function, and clean air are essential for ensuring you receive enough oxygen.
The placenta is composed of tissues from the?
The placenta is composed of tissues from both the mother and the fetus. It is made up of fetal and maternal blood vessels, connective tissue, and other cells that allow for the exchange of nutrients, oxygen, and waste products between the mother and the fetus.
What is the air you breathe that all the body cells need?
oxygen
