2

Function of the 2 heart chambers

Right pumps to lungs left pumps everywhere else

3

Valve found between right atrium and right ventricle

Tricuspid

4

What do valves do

Prevent back flow of blood and separates chambers

5

What valve lies between the left atrium and left ventricle

6

What valve allows blood to flow through right ventricle to pulmonary artery

Pulmonary valve

7

What valve allows blood to flow from the left ventricle into the aorta

Aortic valve

8

What noise is the first sound of the heart beat (lub) caused by

Mitral and tricuspid valves closing

9

What is the second sound of a heart beat (dub) caused by

Aortic and pulmonic valves closing

10

Angina pectoris

Decrease in blood supply to heart causing chest pain

11

Myocardial infarction

Necrosis of the heart caused by deprivation of oxygen for too long or heart attack

12

What does the info on the EKG represent

Electrical activity of contraction of the myocardium

13

What is another term for negative myocytes

Polarized

14

Cells while resting are

Negative

15

Beta one controls

Heart

16

Name the two systems that comprise the autonomic nervous system

Sympathetic and parasympathetic

17

Follow the blood flow of the heart: superior and inferior vena cava to the ____ atrium, past the ___ valve and into the ____ ventricle. Past the ____ valve to the ____ artery to the lungs for oxygen

Right, tricuspid, right, pulmonic, pulmonary

18

Trace the path of the conduction system through the heart: ___ node to the ___ node to the bundle of his to the ___ and finally to the ___

19

The ___ valve lies between the right atrium and right ventricle, while the ___ valve lies between the left atrium and left ventricle

Tricuspid, mitral

20

From the lungs blood travels through the ___ vein to the ___ atrium past the __ valve to the __ ventricle then through the __ valve into the __ where it is pumped into the rest of the body

Pulmonic, left, mitral, left, aortic, aorta

21

Stimulation of the vagus nerve will ___ the heart rate

Decrease

22

Another name for the sympathetic nerve is the cholinergic system

False

23

Insufficient blood flow through the coronary arteries can result in

Angina

24

What is the difference between angina and myocardial infarction

Angina is chest pain due to inadequate oxygenation while myocardial infarction is death of the actual heart muscle

25

What does ischemia mean

Inadequate blood supply

26

What causes a heart murmur

Turbulence in the blood flow across the heart valves
