On an ECG printout, explain the three parts of the cardiac cycle and what each represents in terms of heart action.

What is the benefit of looking at a 12-lead vs. a 4 or 6 lead ECG?

According for FITT recommendations for women who are pregnant, what is the intensity for aerobic activity?

Select one or more:

a. Moderate intensity (3-5.9 METS; RPE 12-13); Vigorous intensity (>6 METs' RPE 14-17)

b. Intensity that permits multiple submax repetitions (8-10 or 12-15) to be preformed to a point of moderate fatigue  

c. A variety of weight and non-weight bearing activities are well tolerated

Discuss the parts of the pacemaker system, and give two examples of cardiac problems related to the disruption of the electrical communication between, at least, two components of the intrinsic conduction (pacemaker.)

The body uses many different types of signals. Types include:

1.   action potentials

2.   cytoskeletal signals

3.   neurotransmission

4.   paracrine/autocrine

5.   endocrine.

1. Qualitatively, how fast is each of these signals transmitted?

2. How do each of these signals differ in their distance of action? Are these contact-dependent, local, or can they affect distant targets?

3. Besides speed and distance of action, what are some advantages and disadvantages of these signal types? Describe as many as you can.

What could happen if cells remain in the cell cycle indefinitely?

2.Some tumor suppressor genes inactivated during multi-step tumorigenesis may be readily identified because of LOH in the chromosomal region carrying them, while others may be difficult to identify in this way. Describe the factors that allow or complicate this identification.

3.     Calculate a numerical value for net filtration pressure in the glomerulus under each of the following conditions. Don’t forget to include units with each answer.

        a. At the afferent end of the glomerular capillaries: glomerular capillary blood (hydrostatic or hydraulic) pressure is 60 mm Hg; hydrostatic (hydraulic) pressure in Bowman’s capsule is 15 mm Hg; oncotic pressure in the glomerular capillaries at the afferent end is 21 mm Hg; and oncotic pressure in Bowman’s capsule is 0 mm Hg. Please show your work.

        b. Does your answer to the above question indicate that filtration or reabsorption is occurring across the glomerular capillaries at their afferent end?

        c. At the efferent end of the glomerular capillaries: glomerular capillary blood (hydrostatic or hydraulic) pressure is 58 mm Hg; hydrostatic (hydraulic) pressure in Bowman’s capsule is 15 mm Hg; oncotic pressure in the glomerular capillaries at the efferent end is 33 mm Hg; and oncotic pressure in Bowman’s capsule is 0 mm Hg. Please show your work.

        d. Does answer to the above question indicate that filtration or reabsorption is occurring across the glomerular capillaries at their efferent end?

        e. What is the average net filtration pressure across the glomerular capillaries in the above 2 problems? Show your work and include units.

        f. Explaining why oncotic pressure in the glomerular capillaries is greater at the efferent end than at the afferent end.
