Embryonic and maternal tissue forming the placenta are?

Embryonic and maternal tissues combine to form the placenta, a vital organ that facilitates nutrient and gas exchange between the mother and developing fetus. The embryonic contribution comes from the trophoblast, which develops into the outer layer of the placenta, while the maternal component is derived from the decidua, the modified endometrium of the uterus. This complex structure not only supports fetal development but also plays a crucial role in hormone production and immunological protection.
