- 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 cyclearrow_forwardWhich of the following statements does NOT correctly describe the events following fertilization? Select one: a. Only the inner cell mass cells in a blastocyst are pluripotent. b. The trophoblast has an important role in maintaining the pregnancy, as it prevents the endometrium from shedding. c. As hCG takes over maintaining the endometrium immediately after implantation, the corpus luteum degenerates into the corpus albican. d. All 16 cells in a morula are truly totipotent, meaning that they can become any cells in the human body.arrow_forwardMonths pass as Ashley has an uneventful pregnancy.
