E. a three-chambered heart

Question 9
Which blood vessels carry blood away from the heart?
A. capillaries
B. venules
C. veins
D. arteries
E. lymph vessels

Question 10
Which of the following is not a correct association?
A. arteries-have muscle linings and are deep in the body
B. capillaries-oxygen and nutrient exchange
C. arteries-high blood pressure
D. veins-high blood pressure and are deep in the body
E. veins-have valves to return blood to the heart

Question 11
"Artery" and "vein" are defined by whether they take blood away or toward the heart. If they were defined by whether they carry oxygenated or deoxygenated blood, we would have to change the name(s) of:
A. the hepatic portal vein to hepatic portal artery
B. the hepatic and renal systems, would have to be switched
C. the pulmonary artery and vein would have to be switched
D. the coronary artery and vein would have to be switched
E. the aorta and vena cava would have to be switched

Question 12
What is the correct sequence a drop of blood returning from the body encounters in the heart chambers?
A. left atrium, left ventricle, right atrium, right ventricle
B. left ventricle, left atrium, right ventricle, right atrium
C. right atrium, left atrium, left ventricle, right ventricle
D. right atrium, left ventricle, left atrium, right ventricle
E. right atrium, right ventricle, left atrium, left ventricle

Question 13
Contraction of the right ventricle forces blood initially into the:
A. pulmonary artery
B. right atrium
C. aorta
D. pulmonary vein
E. left atrium

Question 14
If you were tracing the path of blood from the right to the left side of the heart, you must mention the:
A. aorta
B. hepatic portal vein
C. lungs
D. superior vena cava
E. inferior vena cava

Question 15
A biologist is studying the valve in the human heart which prevents blood from back flowing into the left ventricle. Based on this information you would conclude that he or she is studying which of the following valves?
A. bicuspid
B. pulmonary semilunar
C. vena cava
D. aortic semilunar

Question 17
The alternating expansion and recoil of an arterial wall is termed a(n):
A. ECG
B. diastole
C. pulse
D. hypertension
E. heart murmur

Question 18
The "lub" heart sound is due to the:
A. onward rush of blood to the heart
B. contraction of the aortic muscle
C. closing of semilunar valves
D. the closing of the atrioventricular valves
E. the closing of both the semilunar and atrioventricular valves

Question 19
The pacemaker of the heart is termed the:
A. AV node
B. cardiac center in the medulla
C. SA node
D. vagus nerve
E. Purkinje fibers
