Blood Flow And Hemodynamics

Question 1

Which valve has 3 valves and which side is it on?

Answer 1

Tricuspid valve in the right side

Question 2

The mitral valve is the

Answer 2

Bicuspid valve on the left side

Question 3

Semilunar valves

Answer 3

Pulmonary and aortic valves

Question 4

How many type of fibers do we have in the heart?

Answer 4

Circular longitudinal and oblique

Question 5

Equals the total volume of blood flow through systemic or pulmonary circulation

Answer 5

Cardiac Output

Question 6

Amount of blood ejected from either the right or left ventricle in one beat

Answer 6

Stroke volume

Question 7

Cardiac output equals

Answer 7

Stroke volume x heart rate

Question 8

Frictional resistance to blood flow provided by all the vessels between the aorta and right atrium

Answer 8

Total peripheral resistance

Question 9

Small radius change in radius has a large effect on flow

Answer 9

True; a 5% increase in radius produces > 20% increase in flow at the same P

Question 10

Ventricle contraction

Answer 10

Systolic pressure

Question 11

Relaxing of the heart

Answer 11

Diastolic

Question 12

Represents the driving force averaged over the time of the heartbeat obtained from bisecting the integral of the pressure curve

Answer 12

Mean arterial pressure

Question 13

Lowest velocity of blood flow

Answer 13

Through the capillaries which allows time for exchange of fluid and solutes with the tissues

Question 14

Doppler ultrasound is a test that measures

Answer 14

Cardiac output by bouncing high frequency sound waves off circulating red blood cells and measuring the frequency change in reflected sound

Question 15

Pressure drop is proportional to the

Answer 15

Resistance in each segment of the vascular use

Question 16

The greatest change in pressure is in the

Answer 16

Arterioles

Question 17

Greatest resistance is in the

Answer 17

Arterioles

Question 18

Pulse dampening and distribution

Answer 18

Aorta

Question 19

Distribution of arterial blood

Answer 19

Large arteries

Question 20

Distribution and resistance

Answer 20

Small arteries

Question 21

Resistance- pressure and flow regulation

Answer 21

Arterioles

Question 22

Exchange

Answer 22

Capillaries

Question 23

Exchange, collection and capacitance

Answer 23

Venues

Question 24

Capacitance function- blood volume

Answer 24

Veins

Question 25

Collection of venous blood

Answer 25

Vena cava

Question 26

Why can capillaries withstand high pressures?

Answer 26

Small vessels can withstand high pressures because their radii are small

Question 27

Drop from arterioles and capillaries

Answer 27

70-30= 40
