- Explain why changes in cervical mucus can predict a woman’s monthly fertility?hCG, estrogen and progesterone are hormones that are secreted throughout pregnancy. Answer the following questions about these hormones.1) Identify the structure that initially secretes hCG 2) Describe the function of hCG and identify the trimester where the hCG level is the highest 3) What are the roles of estrogen & progesterone in pregnancy 4) What structure initially secretes estrogen & progesterone? 5) What structure takes over the role of secreting hCG, estrogen & progesterone in the second and third trimesters?Describe the main actions performed by oxytocin. Why parturition can occur without elevated levels of plasma oxytocin?
- Discuss the critical effects of estrogen and progesterone during pregnancy.Identify 3 effects of progesterone on pregnancy. Select one or more: O a. This causes the uterus to remain contracted after delivery to reduce blood loss from the placental site O b. This is produced when the ovarian follicle that encloses the developing egg forms a structure called the corpus luteum O c. This decreases bladder tone leading to an increased risk of urinary infection O d. This prepares the body for pregnancy. It acts as an appetite stimulant Identify 1 effect of the hormone vasopressin in pregnancy. Select one: O a. This has an important compensatory mechanism for restoring blood pressure in hypovolaemic shock such as that which occurs during haemorrhage O b. Promotes the maintenance of the corpus luteum at the beginning of pregnancy O C. Involved in thickening of the endometrium and other aspects of regulating the menstrual cycleDescribe the role of progesterone in pregnancy including what produces it during pregnancy, its role in labor and delivery and how it effects at least two other body systems/tissues during pregnancy.
