Antibodies.
The deoxygenated blood and the baby's waste products pass from the foetus to the mother. The mother can then dispose of these through her systems.
The uterus is an organ and thus part of the mother. Did you mean from the fetus to the mother? If so, the umbilical cord goes from the fetus to the mother
A fetus gets all of it's nutrition from their mother. The mother has all of the nutrients and passes them along to the fetus.
It passes back to the mother through the umbilicus
The fetus receives oxygen from the mother through the placenta. The mother's blood, high in oxygen, passes through the placenta where it comes into close contact with the fetus's blood, allowing for the exchange of oxygen and carbon dioxide. This process ensures that the fetus receives the necessary oxygen for development.
The fetus is supplied with oxygen and nutrients through the placenta, which is connected to the mother's uterine wall. The mother's blood passes through the placenta, allowing oxygen and nutrients to pass from the mother's bloodstream to the fetus. Waste products from the fetus also pass through the placenta into the mother's bloodstream for elimination.
With mammals, the fetus has a connection by its umbilical cord to an organ of the mother, called the placenta. Blood passes through the umbilical cord to the fetus, carrying food and oxygen. The umbilical cord is attached to the fetus at a point you will later call your navel or belly button.
There are many antibodies passed to the fetus. Any and all that she was exposed to would be passively passed to the fetus. These are passive in that the newborn will have to make his own later in life but will keep him from harm for about 6 months.
The structure that pushes the fetus out of the mother is called the uterus.
Yes, there is no danger to the fetus is the mother is type A and baby is type B
