The layer of the heart wall composed of cardiac muscle:
endocardium
myocardium
epicardium
pericardium
Which area of the heart receives blood from the systemic veins:
right ventricle
left ventricle
right atrium
left atrium
The right AV valve is known as the:
aortic semilunar valve
tricuspid valve
biscupid/mitral valve
pulmonary semilunar valve
Pulmonary veins:
transport oxygenated blood to the lungs
transport blood rich in carbon dioxide to the lungs
transport oxygenated blood to the heart
transport blood to the right atrium of the heart
The tricuspid valve is located between the:
right atrium and left atrium
right atrium and right ventricle
left ventricle and pulmonary artery
left ventricle and aorta
The superior vena cava empties:
oxygenated blood into the left atrium
oxygenated blood into the left ventricle
deoxygenated blood into the right atrium
deoxygenated blood into the right ventricle
Which of the following blood vessels carries oxygenated blood:
superior vena cava
pulmonary artery
inferior vena cava
pulmonary veins
The sinoatrial node (pacemaker) is located in the:
aorta
right atrium
left atrium
right ventricle
The path of blood flow within the systemic vascular system is:
arterioles, arteries, capillary beds, venules, veins
arterioles, arteries, capillary beds, veins, venules
arteries, arterioles, capillary beds, venules, veins
arteries, arterioles, capillary beds, veins, venules
Veins:
carry blood away from the heart
branch into smaller vessels called arterioles
transport oxygen-rich blood
often have valves to prevent the back flow of blood
The carotid artery is located in the:
neck
groin
armpit
leg
In which of the following blood vessels, is blood pressure the highest:
veins
arteries
capillaries
arterioles
Freshly oxygenated blood is received by the:
right atrium
right ventricle
left ventricle
left atrium
The myocardium receives its blood supply directly from the:
aorta
coronary sinus
pulmonary arteries
coronary arteries
Which of the following blood pressure readings would be indicative of hypertension:
120/80
110/60
89/60
140/90
What structure divides the left from the right ventricle:
bicuspid valve
interatrial septum
interventricular septum
chordae tendineae
When the ventricles contract, the bicuspid (mitral) valve prevents blood from flowing from the:
right ventricle to the right atrium
left ventricle to the left atrium
left atrium to the right atrium
right atrium to the left atrium
Which one is the correct sequence going from the outermost to the innermost layer of a blood vessel:
tunica media, tunica intima, tunica externa
tunica media, tunica externa, tunica intima
tunica externa, tunica media, tunica intima
tunica externa, tunica intima, tunica media
Varicose veins are caused by:
a loss of elasticity in blood vessels
the accumulation of fatty substances within blood vessels
excessive production of the enzyme renin
incompetent venous valves
Abnormal or unusual heart sounds that often indicate valve problems:
aneurysm
thrombophlebitis
murmurs
atherosclerosis
Myocardial infarction is:
an inflammation of the pericardium that causes the pericardial layers to stick to each other.
a bacterial infection of the endocardium that can cause the heart valves to become stiff and not work properly.
a heart attack that can be caused by coronary vessel blockage resulting in the myocardium being deprived of oxygen.
when arteries become narrowed by fatty plagues developing within the tunica intima.
Blood vessels within the lungs become swollen with blood causing pressure within them to increase and fluid to leak from the circulation into the lung tissue:
angina pectoris
aneurysm
pulmonary edema
pulmonary embolism
Inflammation of the veins resulting in a blood clot forming within a vessel with poor circulation:
thrombophlebitis
endocarditis
atherosclerosis
murmurs
When arteries become narrowed by fatty plaques developing within the tunica intima:
aneurysm
thrombophlebitis
pulmonary embolism
atherosclerosis
Occurs when part of an artery wall weakens allowing it to widen abnormally and balloon outward:
aneurysm
pericarditis
pulmonary edema
atherosclerosis
Situation in which the myocardium is deprived of oxygen and often results in crushing chest pain:
aneurysm
angina pectoris
congestive heart failure
myocarditis
Inflammation of the pericardium that causes the pericardial layers to stick to each other:
endocarditis
pulmonary edema
thrombophlebitis
pericarditis
Bacterial infection of the endocardium that can cause the heart valves to become stiff and not work properly:
endocarditis
murmurs
pulmonary embolism
thrombophlebitis
Clot formed during thrombophlebitis that has become detached and can lead to death:
angina pectoris
aneurysm
pulmonary embolism
atherosclerosis
Progressive condition that reflects a weakening of the heart by coronary atherosclerosis, persistent high blood pressure, or multiple myocardial infarctions:
aneurysm
congestive heart failure
hypertension
thrombophlebitis
Systole is the:
contraction of the atria
contraction of the vertricles
closing of the semilunar valves
pacemaker of the heart
Systolic blood pressure:
indicates how much pressure the blood is exerting against the artery walls while the heart ventricles are at rest.
indicates how much pressure the blood is exerting against the artery walls when the heart ventricles are contracting.
Diastolic blood pressure:
indicates how much pressure the blood is exerting against the artery walls while the heart ventricles are at rest.
indicates how much pressure the blood is exerting against the artery walls when the heart ventricles are contracting.
The number of times the heart beats per minute is:
blood pressure
systole
arterial pulse
diastole
The term for low blood pressure:
hypertension
systolic tension
hypotension
diastolic tension
