AP Lab 10

Completing the Research Notebook for AP Biology Lab #10.....Physiology and the Circulatory System

Resource: Lab Ten, Physiology and the Circulatory System

Page 109 in the AP Biology Lab Manual


Part 1: Title

Develop a title in the form of a question after completing the pre-lab.


Part 2: Objectives (What are the objectives for this laboratory?)


Part 3: Pre-lab Questions

a. Explain the relationship between temperature and rates of physiological processes in ectothermic

organisms and endothermic organisms. (See Campbell page 833 Ectotherms and Endotherms-read

the entire section for good answer)

b. Describe the basic anatomy of a mammal circulatory system (see introduction on lab sheets and

review your text for review of structure of heart and pulmonary and systemic circuits)

c. Describe the path that a red blood cell takes from the right atrium, to your big toe, and back to the

right atrium.

d. Discuss the difference in systolic and diastolic pressure.


Part 4: Methods

Exercise 10A: A sphygmomanometer will be used to measure blood pressure.

Exercise 10B: A test of fitness will be conducted to evaluate fitness based on cardiac muscular

development and ability of the cardiovascular system to respond to sudden changes in demand

(such as change in systolic pressure from reclining to standing, pulse rate from reclining to standing,

and endurance tests).

Exercise 10C: A controlled experiment will be conducted to test the effect of temperature on the

heart rate of

Hypothesis: If_________________________________________, then___________________.


Part 5: Data Tables

Part 7: Graph

Graph the temperature and heart rate data (See page 123)


Part 8: Theme Correlation

Describe two AP Biology themes that were described in this laboratory.


Part 9: Conclusion

How were the circulatory and respiratory systems responding during the activities in exercise 10B?

What data demonstrated these responses?

Demonstrate your knowledge of the function of circulatory system through a good discussion.

Was your hypothesis supported in Exercise 10C? Use data to discuss outcomes.

Demonstrate your knowledge of differences in ectothermy and endothermy as you analyze data from

Exercise 10C.
