5. Unit 9 Project Think “Fight or Flight”!
You are walking across a busy city street.  When you reach the middle of the crosswalk you see that a driver decides to not stop at the red light and is headed right for you. You panic! Explain what happens to the body systems as you react to this situation.
Think “Fight or Flight”!

30. Question #1
An ovum has all the nutrients stored that are required for embryonic development until implantation has occurred. Suggest why the ovum contributes all of these nutrients, whereas the sperm contributes only the genetic information from the father.

31. Question #2
Fertilization usually occurs in the outer one-third of the uterine tube. Why is it important for fertilization to occur at this point, rather than in the uterus or in the inner two-thirds of the uterine tube?

32. Question #3
Soon after fertilization, embryonic cells begin to produce chorionic gonadotropins, which keep the corpus luteum from degenerating. Why is this function important to the developing embryo?

33. Question #4
The corpus luteum degenerates after 5 or 6 weeks after the secretion of chorionic gonadotropins decreases. What then keeps the uterine lining intact during the rest of the pregnancy?
