cardiovascular system
Which of the following procedures involves a segment of a leg vein being used to provide an alternate pathway for blood flow in coronary artery circulation?
Bypass
The pulmonary semilunar valve prevents backward flow into the
right ventricle
The buildup of fatty deposits in the coronary arteries that leads to narrowed arteries and blockages is called
atherosclerosis
The buildup of fatty deposits, fibrin, clotting factors, plaques, and other materials that eventually narrow the arteries and can lead to complete blockages is called
atherosclerosis
The amount of blood that the heart pumps in one minute is
cardiac output
The function of the atrium is to
collect blood and pump blood to the ventricle
Which of the following procedures involves using a contrast dye that is visible in x-rays?
coronary angiography
Which of the following procedures involves a segment of a leg vein being used to provide an alternate pathway for blood flow past a point of obstruction between the aorta and a coronary artery?
coronary bypass
Which of the following is associated with atherosclerosis?
high sugar diet
Blood returning to the heart from the pulmonary circuit first enters the
left atrium
The pulmonary arteries carry blood to the
lungs
The atrioventricular valve on the left side of the heart is the
mitral valve
The heart valves open and close because of
pressure differences
As blood travels from arteries to veins,
pressure drops
Contractions of the papillary muscles
prevent the atrioventricular valves from reversing into the atria.
Which vessel of the heart receives blood during right ventricular systole
pulmonary trunk
The picture above represents a very serious condition where a blood clot has broken free and has traveled to the lungs. What is this condition know as?
Pulmonary embolism
Which vessel of the heart receives blood during right ventricular systole?
Pulmonary trunk
A HR of over 100 beats/minute is called:
Tachycardia
When a clot forms in a coronary vessel and obstructs blood flow to the muscle, the condition is referred to as a(n) ____________________.
coronary thrombosis
When a clot forms in a coronary vessel and obstructs blood flow to the muscle, the condition is referred to as a(n)________________________.
coronary thrombosis
The ______________ ventricle has a greater workload than the ___________________.
left; right ventricle
The time of day that is most hazardous for heart attacks is (the) ___________________.
morning
When the semilunar valves close, the AV valves
open
The right ventricle pumps blood to the
right and left lungs
Blood returning to the heart from the systemic circuit first enters
right atrium
The following is a list of vessels and structures that are associated with the heart. 1. right atrium 2. left atrium 3. right ventricle 4. left ventricle 5. venae cavae 6. aorta 7. pulmonary trunk 8. pulmonary veins
5,1,3,7,8,2,4,6
Which of the following is known as the "silent killer" because it usually has no symptoms?
High Blood Pressure
Exchange between a blood vessel and the cells that surround it can occur only in
capillaries
The amount of blood the heart pumps in one minute is
cardiac output
The superior vena cava empties
deoxygenated blood into the right atrium
The pulmonary veins carry blood to the
heart
The heart is roughly the size of
your fist
Which of the following is a function of the blood?
-transport of nutrients and wastes - transport of body heat - transport of gases - defense against toxins and pathogens
The heart beats approximately ________ times each day.
100,000

All of the above
Which of the following procedures involves using a small plastic ballon to open a narrowed artery?
Angioplasty
Which of the following would you expect to have the lowest resting heart rate?
a trained athlete
Arteriosclerosis can lead to:
all of the above
Which of the following changes in lifestyle are recommended to treat or prevent hypertension?
all of the above are recommendations for preventing hypertension
The symptoms of heart failure include
all of the above are symptoms of heart failure
The condition where there is deficient blood delivery to the heart caused by transient spasms or blockages of coronary arteries is
angina pectoris
The term for pain associated with deficient blood delivery to the heart that may be caused by the transient spasm of coronary arteries is
angina pectoris
The left ventricle pumps blood through the
aorta
Which of the following procedures involves using a small plastic balloon to open a narrowed artery?
ballon angioplasty
The bicuspid valve or mitral valve is located
between the left atrium and the left ventricle
The ______________ valve prevents backward flo into the left atrium
bicuspid
The normal pacemaker of the heart is located in the
sinoatrial node.
The volume of blood ejected from each ventricle during a contraction is called the
stroke volume.
___________________ is to contraction as _______________________ is to relaxation.
systole; diastole
A heart rate of over 100 beats per minute is called:
tachycardia
Blood is supplied to the myocardium by
the coronary arteries.
The following is a picture of a serious medical condition that if left untreated can become dislodged and travel through the blood steam getting lodged in another vessel. What is this condition?
thrombus
Blood flowing into the heart from the venae cavae flows next trough the ____________ valve.
tricuspid
The semilunar valve on the left side of the heart prevents back flow from the
