heart card game

Question 1

What is the volume of blood
pumped by the heart every minute?

Answer 1

Cardiac Output

Question 2

What is the volume of blood
remaining in the left ventricle after
contraction?

Answer 2

End Systolic Volume (ESV)

Question 3

What is the volume of blood in the
left ventricle after the atria have
contracted and the AV valves have
closed?

Answer 3

End Diastolic Volume (EDV)

Question 4

What is the equation for cardiac
output?

Answer 4

Q= SV x HR

Question 5

What is V02?

Answer 5

The volume of oxygen used by the
muscles during exercise

Question 6

What do veins have that arteries don’t?

Answer 6

Valves

Question 7

The muscle pump improves
preload, contractility, or afterload?

Answer 7

Preload

Question 8

Arteries have more of this in their
walls compared with veins.

Answer 8

Muscle

Question 9

How does the muscle pump
work?

Answer 9

When muscles contract they
squeeze blood in veins toward the
heart

Question 10

What variable or variables does
cardiovascular drift effect and how?

Answer 10

After ~30-35 minutes of aerobic
exercise, HR begins to climb and SV
decreases without changes in the
workload of the workout

Question 11

Why do children sweat less than
adults?

Answer 11

Their sweat glands take a higher
temperature to activate

Question 12

When you begin to exercise
precapillary sphincters do what in
the skeletal muscle?

Answer 12

Vasodilate

Question 13

Pound for pound, how does the
heart rate of a child compare with
that of an adults?

Answer 13

Children have a higher heart rate

Question 14

If cardiac output is held constant,
if stroke volume increases, heart
rate will increase, decrease, or stay
the same?

Answer 14

HR will decrease

Question 15

When you begin to exercise
precapillary sphincters do what in
the viscera (gut)?

Answer 15

Vasoconstrict

Question 16

Why does cardiovascular drift
occur?

Answer 16

Blood volume decreases with
sweating, and causes SV to decrease and
HR to climb

Question 17

What are the vessels called that
supply the brain with oxygenated
blood?

Answer 17

The carotid arteries

Question 18

What side of the heart serves as
the pump to the lungs?

Answer 18

The right

Question 19

Are all the valves in the heart
only one-way?

Answer 19

Yes

Question 20

What part of the heart supplies
the openings of the left and right
coronary arteries?

Answer 20

The aorta

Question 21

When listening to the heart beat,
what is the first sound?

Answer 21

The AV valves closing

Question 22

When listening to the heart beat,
what is the second sound?

Answer 22

The semi-lunar valves closing

Question 23

The sound of blood swishing
around in the heart or blowing by a
valve is called a what?

Answer 23

a heart murmur

Question 24

What is the coronary artery
called that branches off the left
coronary artery and encircles the
top of the heart?

Answer 24

The circumflex artery

Question 25

What does the sympathetic nervous system do to the heart?

Answer 25

Speeds it up

Question 26

Where do the coronary veins return their deoxygenated blood?

Answer 26

Into the right atrium

Question 27

After blood moves through a capillary it moves into what vessel?

Answer 27

A venule

Question 28

What is the nervous system that can slow the heart down?

Answer 28

The parasympathetic system

Question 29

Deoxygenated blood returns to the heart in what major vessel?

Answer 29

The vena cava

Question 30

A small artery is called a what?

Answer 30

An arteriole

Question 31

In between each cardiac muscle cells is one of these.

Answer 31

Intercalated disks

Question 32

The intercalated disks of cardiac muscle cells are held together by these

Answer 32

Desomosomes

Question 33

Of all the coronary arteries, this is the most crucial

Answer 33

Left Anterior Descending Artery

Question 34

Why do athletes have a lower resting heart rate?

Answer 34

They have a higher stroke volume

Question 35

The depolarization wave that causes cardiac muscle to contract in a fluid motion flows through these openings in intercalated disks

Answer 35

Gap Junctions

Question 36

The apex of the heart points in what direction.

Answer 36

Downward and toward the left

Question 37

What is the purpose of the Purkinje Fibers?

Answer 37

To depolarize the ventricular walls and the papillary muscles

Question 38

After the SA node fires, where does the impulse travel to next?

Answer 38

The AV node

Question 39

Why is there a pause in the impulse at the AV node?

Answer 39

To allow the atria to push the maximum amount of blood into the ventricles

Question 40

Oxygenated blood returns to the heart via these vessels

Answer 40

Pulmonary veins

Question 41

If the SA node and AV node do not fire an impulse, what is the next mechanism to contract the heart?

Answer 41

The Purkinje Fibers

Question 42

What is the difference between how the SR releases calcium in cardiac muscle versus skeletal muscle?

Answer 42

The cardiac muscle SR has slow calcium channels to prolong the contraction

Question 43

What factors increase how hard the heart can contract?

Answer 43

Hypertrophy Adrenaline

Question 44

What factors can increase afterload?

Answer 44

Hypertension Aerobic and Anaerobic exercise
