What is A

A

Q

A

systemic

91
Q

explain the pulmonary and systemic circuits

A
92
Q

What does the ductus arteriosus turn into shortly after birth (unless theres a defect)

A

ligamentum arteriosum

93
Q

what is the definition of systole

A

it describes contraction events

94
Q

what is the definition of diastole

A

when heart muscle is relaxing

95
Q

what is atrial systole

A

when atria become polarized and contract. A tiny bit more blood moves into the ventricles before the AV valves close

96
Q

what are the two phases of ventricular systole

A

isovolumic contraction phase and ventricular ejection phase

97
Q

what is the isovolumic contraction phase

A

event that follows ventricular filling, the ventricles are in systole. The pressure is higher in the ventricles compared to atria, but lower that the pressure in aorta. (blood isn’t moving and volume of blood isnt changing within the ventricles)

98
Q

what is ventricular ejection

A

follows isovolumic contraction. with the semilunar valve open, blood moves from higher pressure to lower pressure (from left ventricle to aorta)

99
Q

what is ventricular diastole

A

the phase of relaxation at the beginning of passive ventricular filling

100
Q

what is the dicrotic notch

A

a small dip in the pressure wave caused by the closure of the aortic valve

101
Q

where does the 1st heart sound come from (“lub”)

A

closing of the AV valves

102
Q

where does the 2nd heart sound come from (“dub”)

A

closing of the semilunar valves

103
Q

what is a murmur

A

malfunctioninng valve that causes blood backflow that is characterized by a swooshing sound

104
Q

what is systolic blood pressure

A

the highest arterial blood pressure as the heart is contracting and pushing blood in to the arteries

105
Q

what is diastolic blood pressure

A

arterial pressure when the heart is in a relaxed state

106
Q

what is MAP and what is it’s equation

A

MAP is mean arterial pressure that is the average between diastolic and systolic pressure. 1/3 * (systolic-diastolic) + diastolic = MAP

107
Q

what is a sphygnomonometer and how does it relate to sounds of Korotkoff

A

it is the tool to measure manual blood pressure along with a pressure cuff. The sounds heard throught he stethescope are korotkoff sounds
