Chapter 9 – The Cardiovascular System Test
Part One:
Please read each question/item carefully and choose the one, best answer.
1. The cardiovascular system is comprised of
a. the heart, blood, and blood vessels
b. the heart, blood vessels, and lungs
c. the heart, blood, and alveoli
d. the heart, blood vessels, and edema
2. The vessels that bring blood to the heart are called
a. venules
b. arteries
c. veins
d. capillaries
3. All cardiac muscle fibers are autorhythmic and function without neural
messages.
a. true
b. false
4. Blood leaving the left ventricle into the aorta is low in oxygen.
a. true
b. false
5. Angina pectoris is the same as a heart attack.
a. true
b. false
6. The pulmonary veins return oxygenated blood from the lungs to the left
atrium.
a. true
b. false
7. The systolic pressure measures the working heart, the pressure of the
ventricles when they are contracting.
a. true
b. false
8. The condition when muscle contractions are not coordinated is called
a. heart murmur
b. myocardial infarction
c. high blood pressure
d. fibrillation
9. The door or gate between heart chambers is called a/an
a. atrium
b. ventricle
c. valve
d. SA node
10. The heart rests inside a sac called the
a. pericardium
b. capillary bed
c. myocardium
d. endocardium
11. The valve between the left atrium and left ventricle is called the
a. pulmonary valve
b. tricuspid valve
c. mitral valve
d. aortic valve
12. Blood from the lower part of the body, such as the legs, travels to the heart
through the
a. superior vena cava
b. pulmonary vein
c. pulmonary aorta
d. inferior vena cava
13. With a myocardial infarction, muscle tissue dies, but it can grow back.
a. true
b. false
14. With heart murmurs, there are unusual sounds, most often because of
heart valve problems.
a. true
b. false
Part Two: Look at the illustration of the heart, and match the following cardiac
vocabulary to the correct location. Then, write a paragraph describing the cardiac
cycle, where the blood travels through the heart and out of the heart and how it
changes during the process. Write your paragraph on the back of this page.
mitral valve
superior vena cava
right atrium
left ventricle
pulmonary artery
aorta
inferior vena cava
tricuspid valve
pulmonary vein
left atrium
pulmonary valve
right ventricle
aortic valve
