How is the baby fed in the womb?
Nutrients pass through the placenta into the baby through the umbilical cord.
What substances pass between mother and embryo?
Nutrients such as glucose, amino acids, and oxygen pass from the mother to the embryo through the placenta. Waste products like carbon dioxide and urea pass from the embryo to the mother for elimination. Hormones and antibodies can also transfer between the two.
How is the foetus supplied with oxygen and food in the uterus?
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.
