1.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.
2.Label the endocrine glands (A-D) A: ______________ B: ______________ C:
______________ D: ______________ -✓✓A: Thyroid gland B: Adrenal gland C:
Kidney D: Pancreas
3. Label the endocrine glands (A-C) -✓✓A: Pineal gland B: Hypothalamus C: Pituitary
gland
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
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.
