it's funny how this works; myself and the two people i was sitting between were left with whiplash after this morning's 2hr H&AB class and it felt like i was never going to be able to begin to understand wtf that lady was talking about, but then afterwards with a free afternoon i took 3? hours to just take it slow, type out my simple handwritten notes from this morning, stare intensely at diagrams & read thru the lecture slides and U know what.... i'm not afraid anymore<3
NATURE OF NURSING: no classes today but started the beginnings of some digital notes on intro nursing theory, here's what my unfinished sheet on ADLs looks like so far lol!!
HEALTH & APPL. BIOSCIENCES: CARDIOVASCULAR SYSTEM TODAY AUGHHHH i'm TELLING YOU they're releasing NEW BIOLOGY bro WTF IS THIS SHIT !!!!!
blood pressure: force of blood pushing against inside walls of vessels
heart position: slightly left of midline deep to the sternum in the mediastinum (compartment of thorax)
pericardium: tough sac restricts ♡ mvmt -> only moves slightly in thorax
fibrous p.c. = outer covering of tough dense connective tissue
serous p.c. = parietal layer (lines inner surface of fibrous p.c.) + visceral layer (epicardium, covers outer surface of ♡)
pericardial cavity = space between parietal & visceral layers
♡ walls = 3 distinct layers
epi = visceral layer of serous p.c. + connective tissue
endo = lining of ♡ chamber (touches blood)
external ♡ anatomy: bottom point of ♡ = inferior apex; top point of ♡ = superior base -> 2x small superior atria + 2x larger inferior ventricles // separated by coronary sulcus (deep groove, lets veins & arts sit nicely on surface)
aneurysm: abnormal swelling of heart or artery/vein walls // varicose veins -> weakened valves
and now i present to you my desperate attempt to understand all these new tubes I JUST REALIZED I FORGOT THE CORONARY SINUS DRAINING INTO THE R. ATRIUM AUGHHHHH i also drew a diagram on paper of the heart yaaay
