Giving Æ Mandatory or
Choice?
In
the United States, there is a law called the Uniform Anatomical Gift Act, which
gives people the opportunity and choice to donate their organs after they
die. Contrast this with a law in France
that decrees that organs and tissues can be used from a dead person UNLESS the
person has objected in writing.
The French law make a continuous supply of organs available for transplants,
which will save many lives by reducing the wait time for organs. Do you think a government should decide
the fate of your body at death?

Instructions to the Teacher
After learning about the heart and
how it pumps blood, students will show the path of blood flowing through the
heart by threading a string through a dissected heart.
‡
One cow, sheep or pig heart
for each group of students (can be obtained from a butcher or biological supply
company). The heart will need to
be cut in half (either by the teacher or by the students during a previous
dissection lab) so that all 4 chambers and major vessels are visible and
intact. Students will need to
thread the string through the vessels, through the valves and chambers of the
heart and out again through vessels.
If the heart is cut open and lying in the dissection tray, the string
can lay on top of open structures such as the ventricles and atria.

2. Have
students collect materials and begin. You may wish to read the introduction and
instructions with the students.
3. When
students finish threading string through the heart, score and sign off that
part of the test. You may need to remind them to finish the other parts of the
test before cleaning up the lab equipment.

Name______________________________________________________ Period_______ Date_______
Introduction
You have learned structures of the heart and how it pumps blood to various parts of the body. Now you will demonstrate your knowledge by threading a string through the heart to show the path of blood flow through the heart.
´ heart (cut open) ´ small beaker of water ´ colored pencils
´ string or twine ´ dropper
´ dissecting probe ´ scalpel
´ dissecting tray ´ masking tape
1. Obtain the materials listed above. Throughout the test, keep the heart wet with the dropper.
2. Place the heart in the dissecting tray so that the inside of the heart is visible. Thread the string into the heart, starting where deoxygenated blood returns from the body and enters the heart. Continue threading the string through the heart and surrounding vessels in the direction that blood flows. Your string should end where oxygenated blood leaves the heart and goes back out to the body.
3. Next, label the string with masking tape as it enters and leaves the heart. Attach the masking tape to the string in the appropriate places to create 4 labels by writing the following on the tape. Include the arrows to show the direction of blood flow.

Ex:
4
Labels
FROM BODY---->
TO BODY---->
FROM LUNGS ---->
TO LUNGS ---->
4. On the following diagram:
a. Using a green colored pencil, draw arrows that show where you threaded the string through the heart. Make sure your arrows show the direction of blood flow.
b. Label the diagram as you did the string:
From Body; To Body;
From Lungs; To Lungs
c. Color the structures that carry oxygenated blood red and the structures that carry deoxygenated blood blue.

When you have finished threading the string through the heart and labeling the direction of blood flow, raise your hand to have the instructor check off your heart. Keep the heart at your table until you finish the rest of the test.
______________/21 points
5 a. Contrast the walls of the ventricles and atria.
b. Describe how the structure of the atrial and ventricular walls is related to their function.
6 a. Contrast the walls of the veins and arteries.
b. How is the structure of the vein and artery walls related to their function?
7. Describe the function of valves in the heart.
8. Sometimes people have heart valves that don't close completely. What effect would this have on blood flow in the heart?
When you are finished with the test, clean and return all equipment and put the heart in the place specified by your instructor.

How Do Different Practices Affect Heart Rate?
Name________________________________________________ Period___________ Date_________
1. Survey 100 individual's resting heart rates and one practice, attitude or physical characteristic that could affect heart rate.
a. Construct tables and graphs to present the data collected in the survey.
b. Research the practice or characteristic you chose that relates to heart rate.
c. Write a 2 page, double spaced written report that contains your research information and results of your survey.
2. Present the information found to the class in a group presentation.
Watch with second hand
1. Your research question is: Does ________________ affect heart rate? In groups of four, develop one survey question about a personal habit, practice, or physical characteristic that could affect people's heart rates. Make sure as you design your survey that you are surveying only ONE characteristic or habit. For example, if you want to survey heart rates of different genders, take the heart rates of 50 girls and 50 boys that are the same age, have similar eating habits and physical activity levels, and are all resting at the time you take their heart rate. In other words, make this a controlled study. Develop a method for collecting the data in a consistent and organized way. (A table might help you.) As a group, you need to survey 100 people, so at this point you may want to assign each person in the group to survey 25 people. No two groups may test the same characteristic, so when your group has decided, list your characteristic on the board with your names next to it.
2. For the second part of the survey, you will check the participant's heart rate. Make sure everyone in your group agrees on the way your group takes a heart rate. (For example, will you count heart rates for 10 seconds,15 seconds, or one minute?) At the end of this activity, you will compare the person's survey question response to that person's heart rate to see if there is any correlation between the two.
3. Administer the survey to 100 people. You will need to do this outside of class time. If your test limits the number of people you will be able to test (for example, very old age or a particular disease), talk to the teacher about possibly modifying the size of your test group.
4. Collect and analyze the data with your group.
5. Build charts and graphs that communicate the results of your survey in a visual, easy to understand format. Make sure the graphs and charts are neat and large enough to be used in your class presentation. Use color in your graphics to help make your information easy to understand.
6. Find out what current research tells us about the practice of characteristic your surveyed. Possible sources to use include the internet (The American Heart Association has a good home page), encyclopedias, books or magazines dealing with health issues, your textbook, etc. Be sure you quote your sources when you report your findings in your presentation and written report.
7. Compile your research information, results from your survey, charts and graphs into both a written report and a group presentation. Be sure you have visual aids to use in your presentation. Part of your grade on this assignment will come from how well you present your information to the class, so make sure your presentation is well organized and runs smoothly. Every member of the group should have a speaking part and be able to respond to questions.
8. Present your findings to the class. After your presentation, hand in your written report to the
teacher.

Measuring Lung Volumes
The purpose of this performance test is to assess a studentÍs ability to correctly collect data, identify variables, make hypotheses and set up procedures to test their hypotheses.
Students should have a general knowledge of how the lungs work, and be familiar with the terms used to describe lung capacity.
8 lung volume bags
mouth pieces for everyone in the class
(lung volume bags and mouth pieces can be purchased from biological supply companies)
Students should work in pairs when figuring out lung capacity. It takes each pair of students about 5-8 minutes to read the instructions and use the lung volume bags. It should take a class of thirty between 10-15 minutes to calculate lung capacities. You may need to demonstrate how to attach the mouthpiece to the bag, how to empty air from the bag, and how to correctly measure the volume of a breath.
Arrange students in teams (groups) of two. While waiting for a turn to use the bags, students can work on questions 3-7 on the analysis part of the test. Inform students that they are to work on the second part of the assignment once they are finished with the bags.
Instructions section:
Give 2 points if students successfully completed all 6 trials. Give 1 point for each average.
14 points for this section
Analysis section:
3. 3 points if they brainstormed 5 variables.
4. 1 point if they selected a variable
5. 2 points if they wrote a good ñifî statement and 2 points for a logical ñthenî conclusion.
6. 5 points if they came up with a logical way to test their hypothesis.
7. 1 point for creating a graph that would display their data, and 2 points for explaining how they would plot their data on the graph.

Measuring Lung Volumes
Name________________________________________ Period_________
Date__________
1. Use a lung volume bag to measure your tidal volume (amount of air inhaled and exhaled in a normal breath). Breathe the amount of air you exhale in a normal breath into the bag. Twist the bag downward so that all of the air is in the bottom-most part of the bag. Read the measurement at the top of the air in the bag to get the tidal lung capacity in liters. Repeat the procedure 3 times and then take an average of the three measurements. Record your information below. Then help your partner repeat the entire procedure.
trial #1__________________ trial #2_________________ trial #3__________________
average of the three trials_____________________
2. Use the same procedure to calculate your vital capacity, this time blowing the maximum amount of air you possibly can into the bag in one breath and record below. Repeat two more times, record your information, average the three trials and help your partner repeat the procedure.
trial #1__________________ trial #2_________________ trial #3__________________
average of the three trials_____________________
1. What was your tidal volume?
2. What was your vital capacity?
3. Brainstorm at least 5 variables that might affect lung capacities.
4. From your list select a variable that you would like to test. Write the variable below.
5. Make a hypothesis about your variable and its relationship to lung capacity. State your hypothesis in an "If--Then" format.
6. Create a set of procedures that would test your hypothesis.
7. Create a graph that you would use to plot your data. For example, would you use a bar graph, a line graph, a pie graph, etc. Also include how you would plot your data. For example, if you were using a bar or line graph, what would be the X component and what would be the Y component?
