Both the heart and arteries contract to pump blood throughout the body. - ANS-T
Arteries carry oxygen-rich blood to capillaries. - ANS-T
Plasma prevents the loss of blood by causing clotting. - ANS-F
How many chambers does the heart contain? - ANS-4
The human cardiovascular system is considered closed because ______. - ANS-there are no
holes for blood to enter or leave the system

, The failure to deliver blood to the heart due to a narrowing of arteries results in __________. -
ANS-C. coronary heart disease
What distinguishes high blood pressure from conditions such as arteriosclerosis and
atherosclerosis? - ANS-D. High blood pressure has no symptoms.
High levels of cholesterol can first lead directly to __________. - ANS-B. arteriosclerosis
Which of the following is NOT a treatment for high blood pressure? - ANS-an LDL-rich diet
What are the odds of nonsmokers developing cardiovascular disease when compared to
smokers? - ANS-Nonsmokers are half as likely to develop cardiovascular disease.
A rapid, irregular heartbeat is a symptom of __________. - ANS-heart failure
The maximum oxygen uptake is known as the __________. - ANS-A. VO2 max
As exercise levels increase, which of the following physiological changes occurs in the
respiratory system? - ANS-B. The lungs expand in size.
Your maximum oxygen intake is a measurement of the ability __________. - ANS-D. all of the
above are measured by maximum oxygen intake
Optimal cardiorespiratory fitness requires a BMI of __________. - ANS-A. 18.5 to 24.9
