Explain two reasons why a woman with low levels of LH would not be able to become pregnant.
- answer✔✔(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.
- answer✔✔(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: ______________ - answer✔✔A: Thyroid gland B: Adrenal gland C: Kidney D: Pancreas
3. Label the endocrine glands (A-C) - answer✔✔A: Pineal gland B: Hypothalamus C: Pituitary
gland
Explain the concept of negative feedback and how it helps to maintain homeostasis. -
answer✔✔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. - answer✔✔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.
