striations
32
B: what landmarks are being pointed to? What can be found in them.
intercalated discs that have gap junctions and desmosomes

What is A
pulmonary
90
what is B
systemic
91
explain the pulmonary and systemic circuits
92
What does the ductus arteriosus turn into shortly after birth (unless theres a defect)
ligamentum arteriosum
93
what is the definition of systole
it describes contraction events
94
what is the definition of diastole
when heart muscle is relaxing
95
what is atrial systole
when atria become polarized and contract. A tiny bit more blood moves into the ventricles before the AV valves close
96
what are the two phases of ventricular systole
isovolumic contraction phase and ventricular ejection phase
97
what is the isovolumic contraction phase
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
what is ventricular ejection
follows isovolumic contraction. with the semilunar valve open, blood moves from higher pressure to lower pressure (from left ventricle to aorta)
99
what is ventricular diastole
the phase of relaxation at the beginning of passive ventricular filling
100
what is the dicrotic notch
a small dip in the pressure wave caused by the closure of the aortic valve
101
where does the 1st heart sound come from ("lub")
closing of the AV valves
102
where does the 2nd heart sound come from ("dub")
closing of the semilunar valves
103
what is a murmur
malfunctioninng valve that causes blood backflow that is characterized by a swooshing sound
104
what is systolic blood pressure
the highest arterial blood pressure as the heart is contracting and pushing blood in to the arteries
105
what is diastolic blood pressure
arterial pressure when the heart is in a relaxed state
106
what is MAP and what is it's equation
MAP is mean arterial pressure that is the average between diastolic and systolic pressure. 1/3 * (systolic-diastolic) + diastolic = MAP
107
what is a sphygnomonometer and how does it relate to sounds of Korotkoff
it is the tool to measure manual blood pressure along with a pressure cuff. The sounds heard throught he stethescope are korotkoff sounds
