oh well im still glad one options down and gone. two more to go by this week. and then hcl o levels on the 31st, then FAM on 12th nov, then zoom to 5th dec delf. yikes
yeah and orionids star party to look forward to. scitare farewell and bye bye to all the juniors and stuff. i'll MISS YOU PPL!
sniff.
anw back to the main point. i dissected a frog today. what's more, it was ALIVE! that was the freaky bit. we had to pull the skin up and slowly cut it out carefully without piercing any blood vessels, and then we pinned the skin to both sides. then we had to cut some slits and tie knots to cut off the blood flow so that we can minimise the blood. then we had to cut the cartilage through to the pelvic girdle and stuff, and then pin here, pin there, and then all the innards will spill out.
literally.
we had to add water too, so the gooey weirdy fat tissues and whatever crap started floating around. oh and we found out our frog was somewhat dead. its heart wasn't beating. we were rather relieved.
much to my
the super alive frog jerked every once in a while! it's like they were cutting its skin and then it would totally move its arms which were pinned down and the whole bench would scream. it was really, really freaky. who ever heard of moving frogs who were unconscious in the middle of dissection???
and it would move every once in a while too. imagine how scary it must be to be cutting something like that. lucky our frog was pretty much dead.
THEN chelsea was trying to resuscitate our frog by doing cpr on it. the heart pumping thingy u know, she being red cross and all. she was going one and two and three and four and five while pressing its heart -u think: "EEW GROSSS" but i was pretty much immune to it after a while-
and then the heart started pumping.
boom-boom. boom-boom.
once every 10 seconds or so, which was way too slow and abnormal. then the heart stopped beating altogether. so was this frog alive or dead? with all its innards splayed out across the tray and stuff we would rather it safely dead but...
i realised when u add water, the heart starts pumping again.
we brought the frog back to life. after torturing it so much, cutting it up and digging around its kidneys and ovaries (oh yeah it was a female. not pregnant at least. phew.) just can't imagine how much pain it endured.
yet somehow, some way, it just held on with its strong will to life. it lived on no matter what. no matter it was being poked at by our scapels and scissors, no matter it was being pinned down, no matter it was dying. the heart went on pumping.
we were then supposed to dispose of it in a dustbin. it's still ALIVE! we were sorely tempted to sew it together and set it free back into the wild, but i guess it's totally impossible. im quite sure we punctured its organs or something when cutting it open. also we didn't have needles, and im sure we'll make an even worse mess out of it. her i mean. ok i just can't think of it as a HER. >.<
and oddly, it wasn't breathing actually. how could the heart survive without oxygen? hmm. maybe it was breathing so shallowly we couldn't see. hmm. maybe we should have cut up its head and looked at its brains.
anw this was an experience of a lifetime. it's super disgusting and gross and freaky, not just that it's got clammy cold skin, blackish gall bladder and has loads of fat tissues (yes it was a fat frog! ^^), but more of bcos it was alive. it made ALL THE DIFFERENCE. seeing a heart pump was really more than enough experience to last me a lifetime.
im so not going to be a surgeon. i don't really want to be a doctor anw. eurgh. the poor frog doesn't even have anesthesia!
btw. female frogs are "fatter" bcos they have extra organs (ovaries and stuff for pregnancy). not fair. ):
