At placenta, you have a membranes from mother and fetus come in close contact. The area of contact is fairly large, much more than you can imagine. Here the blood from mother and the fetus come in close contact, but does not get mixed up. Through this so called placental barrier, only very small molecules can pass. So all the amine acids, glucose, fat molecules ( may be fatty acids and glycerol) vitamins and minerals along with water can pass through this membrane. Globulin can pass but not albumin. That is the beauty of Nature.

In late pregnancy, the mean partial pressure of oxygen (P02) in maternal blood is considerably higher than in fetal blood. As a consequence, oxygen readily diffuses across the placenta from maternal to fetal blood. Despite its low PO2, fetal blood is able to transport essentially the same quantity of oxygen to tissues as maternal blood. This is because the hemoglobin concentration in fetal blood is about 50% higher than in maternal blood, and the majority of hemoglobin in the fetus is fetal hemoglobin, which has a higher oxygen carrying capacity than adult hemoglobin.
Carbon dioxide is produced abundantly in the fetus, and the PCO2 of fetal blood is higher than maternal blood. Carbon dioxide therefore diffuses from fetal blood, through the placenta, into the maternal circulation, and is disposed of by expiration from the mother's lungs.

What provides food and oxygen for a developing embryo?
The Placenta uses a the process of diffusion to diffuse the nutrients from the mothers blood into the babies. Then the umbilical cord carries the nutrients to the baby to the Placenta. Answer is Placenta
How are living organisms adapted to increase posibility of diffusion?
they have a large surface area and are important
How are synapses adapted for diffusion?
The synapse releases a chemical that can diffuse across the gap between two neurones. The synapse has a large surface area, which means diffusion of the chemical can occur at a higher rate.
Does the egg stick to the placenta in the womb?
The placenta is created by the egg.
Answer which organ is made both from tissue of the embryo and the mother .?
Placenta
Describe how the placenta is adapted for the exchange of substances?
iya ladddddddd

How is a fish specialy adapted to exchange gases by diffusion?
XD
What are the parts of the body that adapted to aid diffusion?
lung and heart
The human female reproductive system is adapted for?
Transport of Oxygen through the placenta to the fetus
What is one adaptation of placenta helping the rate of diffusion?
Nutrients, oxygen, and disease fighting substances.You're welcome because you don't have to read aye? xD
How are living organisms adapted to increase posibility of diffusion?
they have a large surface area and are important
How is the placenta adapted for its function?
The structure of the placenta is related to its functions because its functions is to support the embryo/foetus in ways such as providing it with nourishment, and oxygen which explains the relevance of the placenta to its function of supporting the growing individual.
The egg of a mammal is smaller than that of a bird because the embryo of the mammal obtains its nutrients from the what?
Placenta through the process of diffusion
How is Alveoli well adapted to diffusion?
The alveoli have very thin walls, which allow for rapid diffusion into the surrounding capillaries. There are also many alevoli in the lung, and that increases the surface area dramatically, allowing for more diffusion to occur
How alveoli adapted to their jobs?
adapted by having a big surface area so it can absorb more oxygen and it contains lots of oxygen. Also it has very thin tubes for diffusion.
What structure carries blood between the fetus and the placenta?
Umbilical Cord
