carries impulses to left atrium

Question 18

Atrioventricular Node

Answer 18

help carry impulse to Bundle of His

Answer 19

carries impulse to ventricles

Question 20

P wave

Answer 20

atria contracting

Question 21

QRS wave

Answer 21

ventricular contraction

Question 22

S-T interval

Answer 22

end of contraction

Question 23

T wave

Answer 23

ventricular relaxation, getting ready for next contraction

Question 24

Tachycardia

Answer 24

hear beat per min over 100

Question 25

Bradycardia

Answer 25

beats less than 40 per min

Question 26

systolic

Answer 26

pressure being exerted on your artery wall

Question 27

diastolic

Answer 27

pressure on artery wall during relaxation

Question 28

Normal BP

Answer 28

systolic: less than 120 diastolic: less than 80

Question 29

Elevated BP

Answer 29

120-129, more than 80

Question 30

Crisis BP

Answer 30

over 180, 120 and higher

Question 31

Stage 1 hypertension

Answer 31

130-139, 80-89

Question 32

Stage 2 hypertension

Answer 32

140 or higher, 90 or higher

Question 33

Blood Vessels

Answer 33

transport O2, eliminate CO2

Question 34

Tunica Externa

Answer 34

contains nerves, structure and support

Question 35

Tunica Media

Answer 35

contains elastic fibers to widen when needed, helps to keep blood going in one direction

Question 36

Tunica Interna

Answer 36

made up of simple squamous epithelium helps regulate blood pressure, helps with no blood clotting

Question 37

Arterioles

Answer 37

same 3 layers just not as big in diameter, primarily regulates blood pressure

Question 38

Capillaries

Answer 38

smallest in diameter, gas exchange O2 in CO2 out, the higher the metabolism of the organ the more capillaries there are

Question 39

venuoles

Answer 39

same layers as arteries but diameter is less

Question 40

Veins

Answer 40

transport blood under low pressure, thinner walls, less elasticity
