Answer 28

re polarization of ventricles

Question 29

High K+

Answer 29

decreases the rate of contraction

Question 30

High Ca+

Answer 30

prolong contractions

Question 31

systolic

Answer 31

when the ventricles contract

Question 32

diastolic

Answer 32

ventricles relax

Question 33

murmurs

Answer 33

abnormal whooshing sound mainly from a leaky valve

valve purpose

Answer 40

regulates blood flow and separates the top and bottom chambers

Question 41

arteries get smaller and smaller as they spread through the body

Answer 41

true

Question 42

depolarization of SA node

Answer 42

decreases the permeability of K+, causes depolarization of heart

Question 43

depolarization of AV node

Answer 43

impulse is delayed and allows he atria to contract completely

Question 44

purkinje fibers

Answer 44

causes the ventricles to contract as a unit

tunica intima

Question 46

tunica externa makeup

Answer 46

connective tissues, collagen, and elastic fibers

Question 47

arteries do not have valves, except in the case of the pulmonary and aortic vavles

Answer 47

true
