, Explain two reasons why a woman with low levels of LH would not be able to become
pregnant. - CORRECT ANSWERS-(1) LH acts on the ovary to cause ovulation to
occur. (2) LH causes progesterone release to facilitate potential fertilization of the
egg and pregnancy. Progesterone is a key hormone for the maintenance of
pregnancy.
Would you expect a female to have testosterone in their bloodstream? Explain why or
why not. - CORRECT ANSWERS-(1) Yes. Both male and female bodies produce "all"
the sex hormones. However, the ratios are different. (2) The adrenal glands are
largely responsible for producing this "opposite" hormone that the ovaries would not.
Label the endocrine glands (A-D) A: ______________ B: ______________ C:
______________ D: ______________ - CORRECT ANSWERS-A: Thyroid gland B:
Adrenal gland C: Kidney D: Pancreas
3. Label the endocrine glands (A-C) - CORRECT ANSWERS-A: Pineal gland B:
Hypothalamus C: Pituitary gland
Explain the concept of negative feedback and how it helps to maintain homeostasis. -
CORRECT ANSWERS-1- The effect or increased level of the hormone acts to shut
down the con!nued release of the hormone. 2- The brain is constantly monitoring
hormone levels to keep levels within a certain range or set-point (homeostasis).
Nega!ve feedback is a way of "turning off" hormone produc!on when the desired level
is achieved
4. Explain the concept of positive feedback. Give an example of a hormone that works
through positive feedback. - CORRECT ANSWERS-1- Positive feedback is the action
of a hormone increasing the production of that hormone. (This is the opposite of
negative feedback). 2- One example is the action of oxytocin causing the uterus to
contract during labor. Oxytocin enhances the effect of the uterus contractions,
causing more oxytocin to be released. The positive feedback loop is stopped once the
baby is born and the uterus no longer needs to contract, stopping the production of
oxytocin.
