How does the embryo get nourishment inside the mothers body?
- The embryo gets its nutrition from the mother’s blood with the help of a tissue called placenta .
- This is a disc embedded in the uterine wall, containing villi on the embryo’s sides of the tissue.
- The villi increases the surface area for the transport of glucose, water, amino acids, oxygen from mother’s blood to embryo.
- The waste material and carbon dioxide generated by the embryo are also transferred to the mother’s blood through placenta.
- The fetus and placenta are attached by umbilical cord.
