birth, the umbilical cord is clamped and the baby no longer receives oxygen and nutrients from the mother. With the first breaths of life, the lungs begin to expand. ... The closure of the ductus arteriosus and foramen ovale completes the transition of fetal circulation to newborn circulation.

Answer:

The circulatory system of the foetus and that of the mother are connected by an umbilical cord that attaches the placenta to the fetus. The separate circulatory system facilitates quick diffusion of nutrients, metabolic waste and respiratory gases between the foetus and the mother. Also placenta acts as a shield for the baby against bacteria and other pathogens.
