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

Which of the following BP readings would indicate hypertension?

170/95

Which of the following blood pressure readings would be indicative of hypertension?

170/96 in a 50 year old man

there are _______ pulmonary veins

4

Why is atherosclerosis especially dangerous when found in the coronary arteries?

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

aorta

Which of the following descriptions matches the term near the left fifth intercostal space?

apex of heart

Blood is carried away from the heart by

arteries

The term used to describe fluid collecting in the pericardial cavity that restricts the movement of the heart is known as

cardiac tamponade.

Hypertension is a(n)

consistently elevated blood pressure

Hypertension is defined as a(n)

consistently elevated blood pressure.

Which of the following is NOT a risk factor for cardiovascular disease?

consumption of aspirin

The atrioventricular valves permit blood flow

in one direction only
