How does the embryo get nourishment inside the mother's body?


There are two connections that provide nourishment to the embryo inside the mother’s body-

• Villi- these are finger like projections on the outer tissue of the embryo, in the uterus. Villi provide a large surface area for exchange of nutrients and oxygen.


• Placenta- embedded in the uterine wall, provides the embryo with oxygen and nutrients from mother’s blood. Placenta also removes the nitrogenous waste materials produced by embryo.
