LAB: Virtual Blood Pressure

You have performed the Virtual Blood Pressure Lab. Transcribe your responses into the appropriate spaces below.

Question 1 (1 point)

State the Purpose of this lab.

Question 1 options:

Question 2 (1 point)

State the Objective of this lab.

Question 2 options:

Question 3 (1 point)

State a Problem about the relationship of age and gender to blood pressure.

Question 3 options:

Question 4 (1 point)

Use your knowledge about the heart and the circulatory system to make a Hypothesis about how the average blood pressure for a group of people would be affected by manipulating the age and gender of the group members.

Question 4 options:

Information

You will proceed to follow the Procedure as outlined in the virtual lab. You will be collecting information and recording it in charts. You will then graph the informaiton from your data tables. Place the information under the Observations heading. Consider the following questions as you start your investigation:

Question 5 (2 points)

How will you use the investigation screen to test your hypothesis? What steps will you follow? What data will you record?

Question 5 options:

Question 6 (2 points)

For your Observations, place copies of your charts in the space provided.

Information

For the sake of consistency, you are being provided with an accurate graph for the data gathered in this lab. Use this graph to answer the following questions where appropriate.

Compare it to your own graph – if yours is significantly different, then you should take the opportunity to redo this lab and/or ask for help from your instructor.

Question 7 (1 point)

Write out one sample set of Calculations that you used to complete the table of average blood pressures for age range and gender.

Question 8 (2 points)

Analyze the result of your experiment. Select all the patterns that you should have observed.

Question 8 options:

Between the ages of 18 and 24 and 25 to 34, the average blood pressure decreased in both genders.

As both genders aged, the blood pressure increased.

Between the ages of 18 and 24 and 25 to 34, the average blood pressure increased in both genders.

In the 11 to17 age group, the males started off with a lower average blood pressure than the females.

Females exhibited a lower average blood pressure than males.

In the 11 to17 age group, the females started off with a lower average blood pressure than the males.

Males exhibited a lower average blood pressure than females.

As both genders aged, the blood pressure decreased.

Question 9 (2 points)

During the course of your experiment, did you obtain any blood pressure readings that were outside of the average range for the group being tested? What did you notice on the medical charts for these individuals that might explain their high readings?

Select all the possible reasons the reading where outside the average range.

Question 9 options:

high-salt diets

low carb diet

too much exercise

family history of hypertension

athletic

alcohol

Obesity

under weight

Question 10 (3 points)

Select all the factors associated with hypertension.

Question 10 options:

a diet low in fruits and vegetables

a diet high in fats

high-salt diet

family history of hypertension

alcohol use

a diet high in fruits and vegetables

a diet low in fats

lack of exercise

too much exercise

Obesity

Question 11 (1 point)

What effect might obesity have on blood pressure?

Question 11 options:

Obesity decreases blood pressure.

Obesity increases blood pressure.

Obesity doesn't usually change blood pressure, however it does increase the person's risk stroke.

Obesity doesn't usually change blood pressure, however it does increase the person's risk of heart failure.

Question 12 (1 point)

Does obesity alone cause a person to be at risk for high blood pressure?

Question 12 options:

Yes, is the only factor that can contribute to high blood pressure. The other factors don't really contribute to high blood pressure just an unhealthy lifestyle.

Obesity is not the only factor that can contribute to high blood pressure. However, many people who are obese follow a poor diet and exercise regime, which are also risk factors.

Obesity effects many aspects of life, however high blood pressure should not be a major concern for most people.

Yes, is the only factor that can contribute to high blood pressure.

Question 13 (1 point)

Arteriosclerosis will also increase blood pressure—hardening and narrowing of the artery walls will increase fluid pressure within the circulatory system.

Question 13 options:

True

False

Question 14 (1 point)

Factors such as poor diet can affect the kidney (nephron) in its absorption and filtering of the blood.

Question 14 options:

True

False

Question 15 (3 points)

Conclusion

Did the result of your experiment support your hypothesis? Why or why not? Based on your experiment, what conclusion can you draw about the relationship of age and gender to group blood pressure averages?

Question 15 options:

Information

For the sake of consistency, you are being provided with a heart rate recovery graph. Refer to this graph when answering the questions that follow.

Question 16 (2 points)

How would this graph compare to the graph of an elite athlete?

Select the statements that woud most likely be true of an elite athlete.

Question 16 options:

They have a slower return to their resting heart rates.

They would likely not reach as high of a heart rate during three minutes of exercise.

Elite athletes would be slower to return to their resting heart rates.

Elite athletes would likely be able to lower their heart rates during relaxation.

They would likely reach a higher heart rate faster during three minutes of exercise.

Elite athletes would be able to quickly return to their resting heart rates.

They have a faster return to their resting heart rates.

Elite athletes wouldn't be able to keep their heart rates higher during relaxation.

Question 17 (2 points)

If this graph represented you, what do you think this graph indicates about your cardiovascular health? Why?
