Class 12 NEET Biology Human Reproduction Questions Part 2

The correct answer is option (1) as
• Parturition is induced by a complex neuroendocrine mechanism. The signals for parturition originate from the fully developed foetus and the placenta that induce mild uterine contractions called foetal ejection reflex.
• Placenta acts as an endocrine tissue and produces several hormones like hCG, hPL estrogens, progestogens, etc.
• The milk produced during the initial few days of lactation is called colostrum that contains several antibodies absolutely necessary to develop resistance for the new-born babies.
