Best Answer

The reproductive system of the female, particularly the placenta which is attached to the uterine wall (the uterus). Maternal blood vessels are "coiled up" next to placental blood vessels and nutrients and oxygen, as well as waste products from the developing fetus, pass the walls of both sets of vessels through a process known as osmosis. Their is probably some active diffusion as well, if I remember correctly, to aid in the transfer of larger molecules. Blood does not typically exchange in large quantities between the mother and baby in a healthy pregnancy, though their may be some incidental exchange, particularly during birth.

The nutrients and oxygen exchanged and given to the infant then travel through the umbilical cord to the developing child.

The mother supplies all the fetus's needs through a blood vessel (Umbilical cord) from her placenta to the baby's belly. The connection to the belly is called the 'belly button" or navel after the vessel drops off after birth.

A baby gets all of his food, as well as his oxygen and water, from its mother's bloodstream. The baby's waste products (like C02) are disposed of in the mother's blood stream as well. It is a two-step process.

In the placenta, the mothers blood flows in to a network of blood vessels and capillaries. Molecules in the mother's blood like glucose, proteins, fats, oxygen, etc. flow out of the mother's blood supply and are absorbed into another network of blood vessels and capillaries containing the baby's blood supply. The baby's blood then flows through the umbilical cord back to the baby.

So when the mother eats a hamburger or a banana, the molecules of glucose, proteins, fats, vitamins, etc. are absorbed into the mother's blood stream by her small intestine. The molecules flow to the placenta, are transfered to the baby's bloodstream and flow to the baby through the umbilical cord.

That is why proper nutrition is very important for the mother and the baby.
