The placenta facilitates the exchange of various molecules between the maternal and fetal circulations. Key molecules that cross the placenta include oxygen and carbon dioxide, nutrients such as glucose and amino acids, and waste products like urea. Additionally, antibodies can transfer from the mother to the fetus, providing passive immunity. Hormones and other signaling molecules might also pass through, playing roles in fetal development and maternal adaptations.
What else can I help you with?
Is the inter-molecular space among gas molecules narrow?
No, it is not narrow.
What property of molecules make gases fill the spaces available to them?
The inter molecular spaces
How do absorbed molecules travel to the rest of the body?
From digestion to inter-cellular space through to blood vessels, in which the blood then brings the molecules to rest of the body
When a substance is raised to its melting teperature what happens to the atom or molecules?
The inter-molecular bonds between the atoms/molecules are broken, releasing the atoms/molecules from a ridged structure to a freely moving mass.
What are the similarities of solids and liquids?
They are all forms of matter. They are identified by the inter-molecular spaces between their molecules.
Is Dipole-dipole forces a intramolecule force?
No. They are inter molecular forces acting between two different molecules.
What is the medical term meaning abnormal implantation of the placenta?
Placenta previa, placenta accreta, placenta increta, and placenta increta are all conditions stemming from abnormal implantation of the placenta.
Why solids is not compressible why?
solid is a state in which molecules are closely packed than liquids and gases. the inter molecular distance between the molecules of solids are less or negligible.thats why the solids are not compressible
How does solid turn to liquid?
Solids are made up of molecules which have more intermolecular attraction. So these molecules are held together closely. But in case of liquids the inter molecular attraction less. So there is inter molecular space between the molecules. They are not very close to one another. When the inter molecular attraction between the molecules is lost or reduced the solids turn into liquids. When the solid is heated because of the heat the kinetic energy of the molecules is increased and the molecules start moving away from each other. So the inter molecular attraction is lost or reduced. So the solid turns into liquids.
What makes the boiling pint of liquids all different?
it depends on the inter-molecular bonds between the atoms/ions/molecules
What molecules does not obey the octet rule?
BF3 and other Lewis acids. Also BrF5 and other inter-halogen compounds.
What type of inter molecular forces hold oxycontin molecules together?
Hydrogen bonding, dipoles, and London dispersion forces.
