CHAPTER FIFTEEN
Cardiovascular System
OUTCOMES 15.2, 15.3
1. What structures and properties should an artif
cial heart have?
OUTCOMES 15.2, 15.3
2. Why is ventricular f
brillation more likely to be liFe threatening
than an atrial f
brillation?
OUTCOMES 15.2, 15.4, 15.6, 15.7
3. IF a cardiologist inserts a catheter into a patient’s right Femoral
artery, which arteries will the tube have to pass through to
reach the entrance oF the leFt coronary artery?
OUTCOMES 15.3, 15.4, 15.5, 15.6
4. How might the results oF a cardiovascular exam diFFer For
an athlete in top condition and a sedentary, overweight
individual?
OUTCOMES 15.3, 15.4, 15.5, 15.6
5. Cigarette smoke contains thousands oF chemicals, including
nicotine and carbon monoxide. Nicotine constricts blood
vessels. Carbon monoxide prevents oxygen binding to
hemoglobin. How do these two components oF smoke aFFect
the cardiovascular system?
INTEGRATIVE ASSESSMENTS/CRITICAL THINKING
OUTCOME 15.4
6. Given the way capillary blood fl
ow is regulated, do you think
it is wiser to rest or to exercise Following a heavy meal? Cite a
reason For your answer.
OUTCOMES 15.4, 15.5, 15.6, 15.8
7. Cirrhosis oF the liver, a disease commonly associated with
alcoholism, obstructs blood fl
ow through the hepatic blood
vessels. As a result the blood backs up, and the capillary
pressure greatly increases in the organs drained by the hepatic
portal system. What eFFects might this increasing capillary
pressure produce, and which organs would it aFFect?
OUTCOMES 15.6, 15.7, 15.8
8. IF a patient develops a blood clot in the Femoral vein oF the
leFt lower limb and a portion oF the clot breaks loose, where
is the blood fl
ow likely to carry the embolus? What symptoms
are likely?
