1. Explain two reasons why a woman with low levels of LH would not be able
to become pregnant.: (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.
2. Would you expect a female to have testosterone in their bloodstream?
Explain why or why not.: (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.
3. Label the endocrine glands (A-D) A: B: C:
D: : A: Thyroid gland B: Adrenal gland C: Kidney
D: Pancreas
4. 3. Label the endocrine glands (A-C): A: Pineal gland B: Hypothalamus C:
Pituitary gland
5. Explain the concept of negative feedback and how it helps to maintain
homeostasis.: 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
6. 4. Explain the concept of positive feedback. Give an example of a hormone
that works through positive feedback.: 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.
