Teaching Strategies
Focus
Introduce students to “The Cardiovascular System” using the following techniques:
1. Have students identify the parts of the cardiovascular system on a diagram or model,
including the chambers, valves, blood vessels, and conduction system. The diagram
can be drawn using poster board, flip chart, overhead, white board, or PowerPoint®.
2. Have students trace and discuss how the blood flows through the heart, lungs, and
body. This can be done by writing each of the structures on a separate sheet of paper.
Give each student one sheet of paper. Then have the students line up in the order in
which blood flows. Once they are correctly in line, have students discuss the
function of the structures they represent.
3. Have students role-play the qualities of the heart, including automaticity,
excitability, conductivity, and contractility.
4. Have students identify components of P, Q, R, S, T, and U waves on a variety of
rhythm strips. The rhythm strips should be obtained in different lead selections to
have QRS complexes with both positive and negative deflections.
5. Discuss how the QRS complex still represents the ventricular depolarization, even
regardless of the QRS complex has a positive or negative deflection.
6. Have students discuss or role-play the actual mechanical movement of the heart
during each of the P, Q, R, S, and T waves.
Strategies
 Have students review the Key Terms for Chapter 2 using the Audio Glossary and Key
Terms Concentration game on the Student CD.
 Encourage students to complete the Checkpoint Questions throughout the chapter and
check their answers. You can remove the answers from the back of the book and use
the Checkpoint Questions as a graded assignment.
 Have students complete each Student CD activity when directed in the text. Have
students print or email their completed Progress Report from the Student CD for
Chapter 2.
 Use the PowerPoint® presentation for Chapter 2, found on the Instructor Resource
CD, for a class lecture and/or review. Use the Test Your Knowledge questions for
discussion.
 Have students complete and check the chapter review in preparation for the final
chapter evaluation.
 Have students play Spin the Wheel on the Student CD individually, in small groups,
or as a class in preparation for the final evaluation.
Assess
 Have students complete the Chapter 2 troubleshooting activity and test from the
Student CD and print or email you their results from the Progress Report.


Using the EasyTest® test bank for Chapter 2, create a written test in two versions for a
final evaluation of student proficiency.
Answer Key
Checkpoint Questions (LO 2.1)
1. The process of transporting blood to and from the body tissues
2. The electrical activity of the heart
Checkpoint Questions (LO 2.2)
1. Myocardium
2. Bicuspid or mitral valve
Checkpoint Questions (LO 2.3)
1. Coronary arteries
2. The pathways for pumping blood to and from the lungs are known as pulmonary
circulation. The pathways for pumping blood throughout the body and back to the
heart are known as systemic circulation. The circulation of blood to and from the
heart muscle is known as coronary circulation.
3. The volume pumped each minute is referred to as cardiac output.
Checkpoint Questions (LO 2.4)
1. The contraction and relaxation of the heart together make up the cardiac cycle.
2. They are both parts of the cardiac cycle.
Checkpoint Questions (LO 2.5a, b, c)
1. Sinoatrial (SA) node (pacemaker), atrioventricular (AV) node, bundle of His (AV
bundle), bundle branches, Purkinje fibers (network)
2. Excitability
3. AV node
Checkpoint Questions (LO 2.6a, b)
1. Depolarization
2. P wave (atrial), T wave (ventricular)
3. Lack of blood causing reduced oxygen to the heart muscle; can result in a change in
the ST segment.

Critical Thinking Application: What Should You Do?
45. (LO 2.5a) The atrioventricular (AV) node is responsible for slowing the electrical
conduction from the atria to the ventricles. This delay in electrical conduction
prevents all of the electrical impulses from stimulating the ventricles.
46. (LO 2.5b) The sympathetic branch of the autonomic nervous system responded to the
stress from the darkness and sound and increased your and your patient’s heart
rates. Without further stimulation, your patient’s heart rates will return to normal. It
would be best to wait for a while until the heart rate is within normal limits before
recording the ECG.
