State three functions of the placenta.
Original Khojo Papers practice question — not from a past board paper.
Answer
The placenta allows oxygen and nutrients to pass from the mother's blood to the foetus; it allows carbon dioxide and nitrogenous wastes to pass from the foetus to the mother; and it secretes hormones such as progesterone that maintain the pregnancy. It also acts as a barrier against many harmful substances and germs.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
The maternal and foetal blood do not mix; exchange takes place by diffusion across the placental membrane.
