Explain two reasons why a woman (1) LH acts on the ovary to cause ovulation to
with low levels of LH would not be occur. (2) LH causes progesterone release to
able to become pregnant. 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 (1) Yes. Both male and female bodies produce "all"
testosterone in their bloodstream? the sex hormones. However, the ratios are different.
Explain why or why not. (2) The adrenal glands are largely responsible for
producing this "opposite" hormone that the ovaries
would not.
Label the endocrine glands (A-D) A: A: Thyroid gland B: Adrenal gland C: Kidney D:
______________ B: ______________ C: ______________ Pancreas
D: ______________
3. Label the endocrine glands (A-C) A: Pineal gland B: Hypothalamus C: Pituitary gland
Explain the concept of negative 1- The effect or increased level of the hormone acts
feedback and how it helps to to shut down the con!nued release of the hormone.
maintain homeostasis. 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 1- Positive feedback is the action of a hormone
feedback. Give an example of a increasing the production of that hormone. (This is
hormone that works through positive the opposite of negative feedback). 2- One
feedback. 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.
