Answer:
Oxytocin, a posterior pituitary hormone. (Ans A)
Explanation:
Oxytocin is known as a posterior pituitary hormone that helps to stimulate strong contractions during labor pain and help to dilate the cervix, push the baby downward and out through the birth canal, drag out of the placenta, and restrict the bleeding at the placental site.
During the birth process, against the cervix, the pressure of the baby and then against the pelvic floor tissues helps to promote contractions and oxytocin hormone. Low levels of oxytocin hormone can cause several problems such as after birth excessive bleeding at the placenta site, contractions slow or stop and making labor time take longer, etc.
