Reminder: Formal Lab write-up due tomorrow. Hard copy to class, uploaded
document to turnitin.com—Class: 10693042 Password: GOVIKS
BACKGROUND SECTION OF LAB
 Biological Significance
o Answer the question: Why are feedback mechanisms important to human
physiology?
 Content from Class
o Provide information about feedback mechanisms

What are feedback mechanisms?

What are 2 types of feedback mechanisms?

What is the difference between the two types?

Which type is most prevalent in humans?
o Provide information about baroreceptors

What are 3 determinants of blood pressure?

Which determinant is measured in this lab?

What is a baroreceptor?

Describe a feedback loop that contains baroreceptors.

What is the relationship between baroreceptors and heart rate?

What is orthostatic hypotension?

Lab 1: Heart Rate Response to Baroreceptor Feedback—Helpful Hints
DISCUSSION SECTION OF LAB
 What was the expected data
o Use info from background and feedback mechanisms to describe what should
have happened in the body during the lab
 Compare expected to actual data
o Explain the data that was actually recorded from lab—include the
following numbers
 Max.
 Min.
 Trend
 Comparison of response to recovery times
o Answer the question: how did the actual data compare to the
expected data?
 Discuss the possible physiological and anatomical reasons for the data
o Was the hypothesis supported or rejected? (remember can’t prove anything
with one experiment)
o Was it evident that a feedback mechanism occurred?
o Was there any errors in lab (explain if yes)
o What limitations are there in this lab (did the equipment actually measure what
was intended?)
o How could this lab be improved? (what other ways can this feedback
mechanism be tested)
o Do all individuals respond exactly the same way—why or why not?
o Was the testable question answered—if yes, what is the answer, if no why not
answered?
