10 In the surgical procedure called a bypass graft, a vessel is removed from a patient and used to make a vascular
bridge that bypasses one of that patient's blocked arteries. A common vessel used for this procedure is the great
saphenous vein. Why do you think a surgeon might use the great saphenous vein instead of the femoral vein or a
large artery?
11 Which of the following is not a factor that determines blood pressure?
a. Cardiac output
b. Blood type
c. Peripheral resistance
d. Blood volume
12 Fill in the blanks: The
is the pressure in the arteries during ventricular systole and
averages about
. The
is the pressure in the arteries during
ventricular diastole and averages about
13 The QRS complex on an ECG represents:
a. depolarization of the atria.
b. repolarization of the atria.
© depolarization of the ventricles.
d. repolarization of the ventricles.
14 Your patient has been admitted to the emergency room with an occupational injury from an industrial saw. He has
lost a significant volume of blood. What effect has this blood loss likely had on his blood pressure, and why?
