How does the embryo get food and oxygen rid of waste?

Food

The embryo receives its food from the mother's blood through the placenta. The placenta is an organ that connects the mother's uterus to the embryo's umbilical cord. The umbilical cord contains blood vessels that carry oxygenated blood from the mother to the embryo and deoxygenated blood from the embryo to the mother. The oxygenated blood from the mother provides the embryo with the oxygen it needs to grow and develop. The deoxygenated blood from the embryo carries away waste products, such as carbon dioxide, that are produced by the embryo's metabolism.

Oxygen

The embryo receives oxygen from the mother's blood through the placenta. The oxygenated blood from the mother diffuses across the placenta and into the embryo's bloodstream. The embryo's heart then pumps the oxygenated blood to all of the cells in the body.

Waste

The embryo's waste products are carried away by the deoxygenated blood that flows from the embryo to the mother through the umbilical cord. The deoxygenated blood carries the waste products to the mother's kidneys, where they are filtered out and excreted in the urine.

In summary, the embryo gets food and oxygen from the mother's blood through the placenta. The placenta also allows the embryo to get rid of waste products.
