उत्तर
Role of oxytocin and relaxin in parturition and lactation:
- Relaxin is the hormone secreted by the placenta that causes the contraction of pelvic joints and promotes parturition (child birth).
- Oxytocin causes the Let-down reflex – the actual ejection of milk from the alveoli of mammary glands. Oxytocin also stimulates the uterus to regain its pre-pregnancy size after childbirth.
