branch

Front 11

Blood moves slowest in which vessels? Why?

Back 11

Capillaries because they have large diameters.

Front 12

Blood moves fastest in which vessels? Why?

Back 12

Artery because they have the smallest diameters.

Front 13

Considering a corresponding artery and vein which has a smaller diameter? Why?

Back 13

Arteries have a smaller diameter because they have to pump blood.

Front 14

volume pulse

Back 14

the change in blood volume with each cardiac cycle

Front 15

What occurrence in the body is responsible for the dicrotic notch?

Back 15

recoil of aorta

Front 16

amplitude

Back 16

height of pulse recording

Front 17

Notice that the slope of the rising edge of the volume pulse is much steeper than the slope of the falling edge. Why?

Back 17

Artery contraction is active [steep rise] and when blood returns, it's passive [not so steep fall].

Front 18

What changes in the finger are represented by the amplitude changes?

Back 18

The amount of blood going to the finger.

Front 19

Does the amplitude range increase or decrease when the person stands? Why?

Back 19

Decreases b/c there is less blood going to the finger.

Front 20

What is the heart rate after the person stands up? Why?

Back 20

73 bpm b/c it had to pump blood to the legs, which is farther.

Front 21

What is the heart rate when the recording returns to normal?

Back 21

Returns to normal

Front 22

Explain ALL of the above changes in terms of “homeostasis”.

Back 22

Your heart only works as hard as your body needs it to and will compensate for changes needed.

Front 23

How much does the heart rate change after exercise?

Back 23

Heart rate increased by 10 bpm.

Front 24

Does the amplitude range increase or decrease right after exercise? Explain.

Back 24

Amplitude increased b/c more blood was required for muscle contraction.

Front 25

What does the change in volume pulse amplitude and heart rate indicate about changes in the volume of blood flowing in the finger?

Back 25

More peripheral blood flow during exercise and even for minutes after.

Front 26

Does your data support the expected need for more energy and blood flow to muscles during exercise?

Back 26

Yes.

Front 27

How does the amplitude (height) of the volume pulse for the cooled finger compare with the recording at normal room temperature?

Back 27

Decreased amplitude and decreased heart rate

Front 28

Can you explain this difference in terms of the effect of cold on peripheral blood vessels?

Back 28

Cold elevates pulse pressure, narrows vessels, and increases peripheral resistance

Front 29

What happens to the volume pulse amplitude when the finger is heated?

Back 29

Increased amplitude and increased heart rate

Front 30

Can you explain this difference in terms of the effect of heat on peripheral blood vessels?

Back 30

Heat stress induces vasodilation, which increases blood flow to area and reduces resistance.

Front 31

What receptors does nicotine attach to in the nervous system?

Back 31

Nicotinic cholinergic receptors

Front 32

Where are these nicotinic cholinergic receptors?

Back 32

Target organs

Front 33

How is tobacco smoke able to cause such a wide range of effects?

Back 33

Due to acting on receptors of both the sympathetic and parasympathetic nervous system

Front 34

radial artery pulse

Back 34

groove medial to styloid process of radius

Front 35

carotid artery pulse

Back 35

side of the neck

Front 36

temporal artery pulse

Back 36

on the temple above and to side of eye

Front 37

brachial artery pulse

Back 37

inner side of biceps

Front 38

popliteal artery pulse

Back 38

behind knee

Front 39

What does your heart rate returning to resting rate indicate about cardiovascular condition?

Back 39

The faster your heart returns to resting value after exercise, the healthier you are.

Front 40

resting (sitting) pulse rate

Back 40

your pulse at rest

Front 41

What is the class average pulse for males?

Back 41

69

Front 42

How do the class' heart rates compare to each other?

Back 42

Females have a slightly higher rate than males

Front 43

How do the class' heart rates compare to expected results?

Back 43

Women are suppose to have a slightly higher rate than men. The rates fit the norm.

Front 44

sphygmomanometer

Back 44

instrument used to measure peripheral blood pressure indirectly

Front 45

manometer

Back 45

used to measure the pressure within the cuff in millimeters of mercury

Front 46

respiration rate

Back 46

how many breaths an individual takes per minute

Front 47

systolic pressure

Back 47

pressure at the time the first sound is heard

Front 48

diastolic pressure

Back 48

pressure at the time the sound stops

Front 49

pulse pressure

Back 49

difference between systolic and diastolic pressure

Front 50

exercise

Back 50

task performed to raise heart rate

Front 51

A patient has the following symptoms: below normal blood pressure and edema in the hands, legs, and feet. Assume that the patient has damage to one of the ventricles of the heart. On the basis of the symptoms, which ventricle do you believe was damaged, and why?

Back 51

The right ventricle because it pumps blood to the body via the aorta.

Front 52

Assume a person has a total of 5000 ml. of blood. What sequence of cardiovascular changes would you expect to occur if 500 ml. were suddenly removed from the person, and why?

Back 52

EPO would stimulate the producation of RBCs and facilitate their maturation to replenish blood loss.

Front 53

In the person from the previous question, suppose the loss of blood continues constantly. What sequence of changes would you expect to occur, and why?

Back 53

Very low blood pressure until the point of death

Front 54

Nicotine is given to a person who does not normally use the drug. For each of these aspects of cardiovascular physiology, what effect, if any, do you expect, and why?

Back 54

Increased peripheral resistance, heart rate, stroke volume, cardiac output, and blood pressure.
