Chapter 52, Problem 1IQ
Summary Introduction
To determine: The effects of the high level of estradiol and progesterone in the absence of pregnancy.
Introduction: Hormones can be defined as a chemical messenger secreted by some glands in the body. These hormones travel in the bloodstream and affect the different processes such as growth, development, and

Students have asked these similar questions
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 cycle
Describe 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.
Discuss the critical effects of estrogen and progesterone during pregnancy.
