AP Flashcards

5711101227	Heart and blood vessels transport:	water, gases, proteins and hormones	0
5711109707	heart location	mediastenum 2/3 of the heart is on the left of the midline	1
5711125050	Stronger pump	left side bottom Left	2
5711130084	Tricuspid valve is	three cusps	3
5711138021	Bicuspid valve is	two cusps	4
5711148360	3 areas that dump blood into the atrium:	coronary sinus, superior vena cava, inferior vena cava	5
5711164204	Pulmonary is	the only place in the body that carries oxygenated blood from the lungs to the left atrium	6
5711180974	Right side of heart consists (Lungs)	right atrium, right ventricle takes low content of oxygen blood from the body and into the lungs for oxygenation	7
5711226043	Left side of the heart consists (Body)	left atrium, left ventricle take high content of oxygen blood from the lungs and into the rest of the body	8
5711257939	Top part of the heart consists	atrial kick weaker pump	9
5711263453	Bottom part of the heart consists	pulmonary and systematic circuits stronger pump	10
5711278947	Blood pH	7.35	11
5711293442	Atrial fibrillation	no atrial kick hypertension, rapid firing through pulmonary veins, clot formation in the atrium	12
5711315753	AV (atrioventricular valves)	allow blood to flow from atria to ventricles	13
5711326539	SA (semilunar valves)	allow blood to flow from the ventricles into the outflow vessels	14
5711383132	chordea tendineae	and contract to prevent inversion or prolapse of these valves on systole (or ventricular contraction) attached to papillary muscle	15
5711576662	papillary muscle	prevents valves from trauma, slowly closing them instead of slamming them	16
5711591570	each cusp makes up	1/3 of the valves	17
5712325653	arteries	carry oxygenated blood, thick because they are under a lot pressure and exposed to high pressures and friction forces	18
5712325654	veins	carry deoxygenated blood, thin because they are exposed to low pressure and minimal friction forces	19
5712341746	epicardium	thin, transparent outer layer	20
5712351925	myocardium	thick middle layer, is composed of cardiac muscle	21
5712393128	endocardium	simple squamous epithelium	22
5712383817	ventricle syncytium	squeezing blood from the apex to the outflow vessels	23
5712370861	atrial muscle syncytium	contracts to force blood into the ventricles	24
5712424628	cardiac output	heart rate x stroke volume	25
5712443166	cardioaccelatory system is found	medulla carotid body and in the arch of the aorta rely information about blood pressure and blood flow to CAS (cardio acc sys)	26
5712886931	heart murmur	abnormal sound that consists of a flow noise that is heard before, between, or after the lubb-dupp or that may mask the normal sounds entirely	27
5712912791	systole	contraction	28
5712912793	diastole	relaxation	29
5712939449	P wave	atrial depolarization	30
5712944932	P-Q wave	time it takes for atrial kick to fill the ventricles	31
5712960489	QRS wave	ventricular depolarization (pumping) and atrial repolarization (filling)	32
5712974278	S-T wave	time it takes to empty the ventricles before they repolarize (fill)	33
5713006382	brachial artery	is where you check blood pressure	34
5713012273	normal blood pressure	120/80	35
5713029636	during atrial systole	the ventricles are relaxed	36
5713039523	during ventricle diastole	the atria are relaxed	37
