Select one:

a) inactivation gates open
b) activation gates closed
c) inactivation gates closed
d) activation gates open and inactivation gates closed

Q2. Which of the following is NOT true of graded potentials?

Select one:
a) They are produced after the binding of neurotransmitter to receptor
b) they will decrease in magnitude as the current flows away from the initial site
c) they are produced at chemically-gated ion channels
d) they are limited in duration by the refractory period of the membrane

1. What are chylomicrons? Why can’t they go directly into the circulatory system? Where do they go?

a.

2. Which of the four basic processes take place in the mouth (you can list more than one)?

3. What are sphincters and what are their purposes?

4. What types of materials are contained in saliva?

5. What is peristalsis? How does it ensure one-way movement?

6. Which of the four basic processes take place in the stomach? List three secretions from the stomach and state what these secretions do?

In the differences between the male versus female urinary tract. EXPLAIN anatomically why one sex has a higher risk of lower urinary tract inflammation or infections. In your explanation, compare the male versus female lower urinary tract including length, locations & nearby organs that might contribute to inflammation or infection?

Of the three topics we explored this Module: Abortion, Euthanasia, and Health Care, which one do you have the strongest stance on? Explain your viewpoint and name an ethical thinker or theory that would support you and why.

2. Which muscle(s) belong to the rotator cuff muscle group?

Discuss the purpose of a screening tool like the DETERMINE checklist. What does this acronym stand for and where would this tool be most appropriately used? How is risk measured with this checklist? Once risk is identified, what is the next logical step?

1) Explain the difference in the functions of low-density lipoproteins and high-density lipoproteins and explain why one is called “good” cholesterol and the other is called “bad” cholesterol.

2) Define vasoconstriction and vasodilation. What is the mechanism of regulation?

3) The heart is called a "double pump" because there are two functionally separate circulations. Trace the pathway of each of these circulations and include the following information: heart chambers involved, major blood vessels involved, and general areas through which the blood flows. Begin with the right atrium.

How does stretch cause smooth muscle contraction (myogenic reflex)? Describe the molecular mechanism.

TLC = 4200, VC = 3200, IC = 2000 Calculate the FRC and RV?
