Question

How does the embryo get nourishment?

Answer 1

Hint: An embryo is a multicellular organism in its early stages of development. In general, embryonic development is the stage of life in sexually reproducing organisms that begins shortly after fertilization and continues through the formation of body structures such as tissues and organs.

Complete answer:
The embryo receives nutrition from the mother's blood via a special tissue known as the placenta. This is a disc that is inserted into the uterine wall. On the embryonic side of the tissue, there are villi. There are blood spaces on the mother's side. This creates a large surface area for glucose, oxygen, and other nutrients to diffuse from the mother to the embryo.

During pregnancy, an organ called the placenta develops in your uterus. This structure delivers oxygen and nutrients to your growing baby while also removing waste products from his or her blood. The placenta attaches to the uterine wall and gives rise to your baby's umbilical cord. The organ is usually attached to the uterus's top, side, front, or back. The placenta may attach to the lower area of the uterus in rare cases. This is referred to as a low-lying placenta (placenta previa).

Thus, The placenta is critical to the fetus's nutrition. It mediates the active transport of nutrients and metabolic wastes across the barrier that separates the maternal and fetal compartments, as well as changing the composition of some nutrients through its metabolic activity.
So, the embryo gets nourishment through the placenta.

Note: While some claim that eating the placenta can prevent postpartum depression, reduce postpartum bleeding, improve mood, energy, and milk supply, and provide important micronutrients such as iron, there is no evidence to support this claim. Placentophagy can be dangerous to both you and your baby.
