Where is the heart located?
In your leg
slightly left to the center of the chest
slightly right to the center of the chest
on the left side of your body
What is the side of the adult heart?
size of an apple
size of a pillow
size of a pea
size of a large fist
Which of the following is associated with oxygenated blood?
Aorta
Pulmonary Artery
Septum
Right Ventricle
Which of the following is associated with deoxygenated blood?
Aorta
Left Ventricle
Tricuspid valve
Septum
The relaxing of the heart is known as
Diastole
Systole
Heart Rate
Cardiac Arrest
The contraction of the heart is known as?
Stroke volume
Diastole
Cardiac cycle
Systole
Which of the following is a Blood vessel?
Ventricles
Heart
Arteries
Septum
Which of the following statements is false?
Plasma is a yellowy liquid containing water
Deoxygenated blood returns to the lungs via the pulmonary artery
55% of the blood volume is made up of blood cells
White blood cells are generally bigger than red blood cells
What are the 3 main types of blood vessels?
Capillaries, veins, aortas
Capillaries, arteries, platelets
Capillaries, veins, platelets
Capillaries, veins, arteries
What prevents blood from flowing back into the atria when the ventricles contract?
semilunar valves
sinoatrial node
atrioventricular node
tricuspid and bicuspid valves
One of the body's largest blood vessels that transports blood from the body region below the diaphragm to the heart
superior vena cava
inferior vena cava
pulmonary trunk
pulmonary veins
When this chamber contracts, it pushes blood through the tricuspid valve
right atria
right ventricle
left atria
left ventricle
This initiates the action potential that causes the heart to beat
Inferior vena cava
Atrioventricular node (AV node)
Superior vena cava
Sinoatrial node (SA node)
When blood leaves this chamber of the heart, it heads to the lungs
right atrium
right ventricle
left atrium
left ventricle
This stops blood from flowing back into the ventricles each time they contract
semilunar valves
tricuspid and bicuspid valves
Sinoatrial node (SA node)
Aorta
This is responsible for distributing electrical impulses through the heart
Atrioventricular node
Sinoatrial node
Inferior vena cava
Superior vena cava
This chamber of the heart receives oxygenated blood from the lungs
right atrium
right ventricle
left atrium
left ventricle
Which best explains why capillary walls are so thin?
because they do not need to pump blood
because they are found only in the smallest organs and tissues
because they maximize diffusion of nutrients
because blood only travels through them slowly
Blood traveling through the systemic circuit goes through the _____ side of the heart and out to the body
right
left
Which of the following is FALSE about pacemaker cells?
They allow the heart to beat on its own
They create their own electrical impulses
They are part of the sinoatrial node and the atrioventricular node
They require depolarizing stimulation from the brain
Blood in capillary beds flows from
arteries to veins
veins to arteries
The phase in the cardiac cycle wherein the ventricles contract is called (a) .
Which valve separates the left atrium from the left ventricle ?
tricuspid
bicuspid
aortic
Blood pressure is expressed as -
diastolic over systolic
pulse over diastolic
systolic over diastolic
Where do you find a pulse ?
artery
vein
capillary
Which of the following events produces the first heart sound ?
Opening of Av valves
Closing of AV valves
Opening of Semilunar valves
Closing of semilunar valves
Second heart sound is heard clearly at which areas of the heart? Mark all that applies.
Aortic area
Tricuspid area
Mitral area
Pulmonary area
Which of the following values represents the stroke volume in a normal adult ?
50 ml
60 ml
70 ml
80 ml
which of the following may cause congestive heart failure ? Select all that apply.
Coronary atherosclerosis
Low blood pressure
myocardial infarcts
Bradycardia
What would happen if a small hole developed in the septum?
The heart would stop pumping.
Blood would move between the right and left side of the heart.
The blood from the pulmonary artery would enter the aorta.
Blood would not flow into the coronary arteries
What type of blood vessel is the MOST muscular and elastic?
artery
vein
venule
capillary
If a person becomes dehydrated, what would there be less of in the blood?
erythrocytes
platelets
leukocytes
plasma
If a person does not have enough erythrocytes, he/she would have difficulty:
fighting infection
carrying oxygen
clotting the blood
transporting antibodies
Jasmine is diagnosed with an aneurysm. What is wrong with one of her arteries?
it is missing
it is twisted
there is a weakness in the wall
there is a clot that is stuck
Which of the following "cause-and-effect" statements is true?
Varicose veins cause an aneurysm
Arteriosclerosis causes hypertension
Leukemia causes phlebitis
an arrhythmia causes an aneurysm
Why is a myocardial infarction life threatening?
A damaged heart muscle cannot pump blood efficiently.
Swollen veins lose elasticity, which decreases blood flow to vital organs.
A minor bump or fall could lead to internal bleediing.
It inhibits the exchange of oxygen and carbon dioxide in body cells.
A heart rate below 60 beats per minute (bpm) is called:
Tachycardia
Bradycardia
Fibrillation
Heart Murmer
Name for the double layered sac that surrounds the heart?
Papillary muscle
Pericardium
Myocardium
Heart Skeleton
What is the function of the pericardium?
It's muscle which makes the heart contract
Keeps heart from swinging around; anchors the heart
It keeps the heart beating (electricity)
