Activity 4: Studying the Effect of Blood Pressure on Blood Flow Rate
Name: Morris
Date: 15 February 2026
Session ID: session
Pre-lab Quiz Results
You scored 100% by answering 4 out of 4 questions correctly.
1 Pressure changes in the cardiovascular system primarily result from
You correctly answered: changes in the force of contraction of the heart.
2 What is the driving force for blood flow?
You correctly answered: pressure gradient.
3 Which of the following is directly proportional to blood flow?
You correctly answered: blood vessel radius and pressure gradient.
4 Arteries close to the heart need to be able to compensate for
You correctly answered: pressure changes.
Experiment Results
Predict Questions
1 Predict Question 1: What effect do you think increasing the pressure will have on the fluid
flow rate?
Your answer: The fluid flow rate will increase.
2 Predict Question 2: Do you think a graph plotted with pressure on the X-axis and flow rate
on the Y-axis will be linear (a straight line)?
Your answer: yes.
Stop & Think Question
1 This experiment uses pressure changes to model
You correctly answered: changes in the force of contraction of the heart.
