Question
Which one of the following is not the function of placenta?
Secretes estrogen
Facilitates removal of carbon dioxide and waste material from embryo
Secretes oxytocin during parturition
Facilitates supply of oxygen and nutrients to embryo
According to the text, the placenta facilitates the supply of oxygen and nutrients to the embryo and the removal of carbon dioxide and excretory waste materials . It also acts as an endocrine tissue, producing hormones like hCG, hPL, estrogens, and progestogens . However, oxytocin is released from the maternal pituitary gland, triggered by the foetal ejection reflex (signals originating from the foetus and placenta), rather than being secreted by the placenta itself .
This question aligns with the NEET BIOLOGY syllabus, specifically targeting concepts from Human Reproduction. Mastering this topic is crucial for scoring well in the upcoming medical entrance examinations. Solving conceptually related problems will help you understand the nuances of these concepts and improve your problem-solving speed.
