intercalated discs
t tubule
Term
Right Atrioventricular Valve is also called
Definition
tricuspid valve
Term
Left Atrioventricular valve is also called
Definition
bicuspid or mitral valve
Term
what are the three layers of the heart wall
Definition
endocardium
myocardium
epicardium
Term
the flap like lateral wall of each atrium is called
Definition
auricle
Term
the _____ veins deliver blood from the lungs to the left atrium
Definition
pulmonary
Term
the right av valve is also known as the _______ valve
Definition
tricuspid
Term
the wall of the atrium is _____ in comparison to the wall of the ventricle
Definition
thin
Term
the _______ prevent backflwo of blood through the heart
Definition
aortic/pulmonary semilunar valves
Term
the blood is flowing from the heart to the ____ during pulmonary circulation
Definition
lungs
Term
blood leaves the ____ side of the heart to enter into systemic circulation
Definition
left
Term
the ____ _____ anchor the av valve to the papillary muscles
Definition
chordae tendinae
Term
before birth, the hole that exists in the atria is called the ___ ____
Definition
foramen ovale
Term
explain the flow of electrical signals in the heart
Definition
sa node
av node
bundle of his

purkinje fibers
Term
what is a moderator band used for?
Definition
used by radiologists to identify right ventricle in prenatal ultrasound
Term
what causes the first heart sound or the "lubb"
Definition
av valve closing
Term
what causes the second heart sound or the "dubb"?
Definition
semilunar valves close
Term
what insturments are used to take blood pressure?
Definition
sphygmomanometer and a stethescope
Term
how far do you inflate the sphygomomanometer to take blood pressure? why?
Definition
inflate the cuff by squeezing the bulb until the pressure exceeds 170mmHg

at this point the brachial artery is compressed tightly, and no blood should be able to flow through
Term
Korotkoff sounds
Definition
sounds heard when taking blood pressure

the first sound you hear when the beating begins is systolic pressure

the second sound will be when the beatings sound subsides (diastolic pressure)
Term
what is a normal blood presure reading?
Definition
120/80
Term
define hypertension
Definition
high blood pressure

systolic is greater than 140 and diastolic is greater than 90
Term
define hypotension
Definition
low blood pressure

when diastolic pressure falls by 20 mm Hg
Term
define heart rate. what is a normal heart rate?
Definition
number of beats per minute, 72 beats per minute
Term
define stroke volume what is average stroke volume?
Definition
the amount of blood ejected from the heart in one beat

avg is 70ml
Term
define cardiac output. how do you calculate cardic output?
Definition
the amount of blood ejected by the heart in one minute

cardiac output= heart rate x stroke vol.
Term
the ___ wave corresponds with atrial depolarization
Definition
P wave
Term
the ____ wave corresponds with ventricular depolarization
Definition

arteries contain a significant muscular layer contribution in the tunica media
Term
