Summary Introduction
Introduction:
Oxytocin hormone is regulated by the positive feedback mechanism. Hypothalamus secretes oxytocin that is stored and released by the posterior pituitary gland. The release of oxytocin occurs during the time of uterine contraction and in milk-let down processes. The secretion of oxytocin hormone is regulated by a positive feedback mechanism.

The physician determines that Ashley is in her twentieth week of pregnancy. Which of the following best describes the development of the fetus at this time (refer to table 29.3)? a. The crown–rump length is 19 centimeters. b. The heart and lungs have fully developed, but the GI tract has yet to form. c. The testes have descended into the scrotum. d. The average weight of the fetus at this time is about 2.5 kilograms.
Breastfeeding releases oxytocin and prolactin, hormones that relax the mother and make her feel more nurturing toward her baby. On the other hand, how does the baby benefit from the production of these hormones in the mother’s body?

- During the first trimester, hCG produced from the chorion maintains the corpus luteum. What is the purpose of maintaining the corpus luteum? Select one: a. The corpus luteum produces relaxin, which thickens the endometrium. b. The corpus luteum ensures that the endometrium does not break down during the first trimester. c. The corpus luteum supports the formation of the placenta. d. The chorion forms the fetal part of the placenta, and the corpus luteum supports the maternal part of the placenta.arrow_forwardThe placenta function to Select one: A. Produce blood cells B.
