Question

Explain the role of placenta development during pregnancy in a human female.

Answer 1

Role of placenta:

1. The placenta aids in the delivery of oxygen and nutrition to the embryo while also removing carbon dioxide and excretory/waste products produced by the embryo.
2. The placenta is attached to the embryo via an umbilical cord, which aids in the movement of substances to and from the embryo.
3. The placenta also functions as an endocrine tissue, producing hormones such as human chorionic gonadotropin (hCG), human placental lactogen (hPL), estrogens, and progestogens.
