Thursday as usual having Bio practical BUT……today is special exp….RAT!! wakaka…(Is your judgement day ratty O.o”)….I’m so exicited tat day, waiting that period to come and ..at last time has come..But I feel so guilty n bad when I look at them( already dead ) bertimbun inside the big aquarium glass that is closed wit penutup,…looks like all “sleeping” in the coffin(memang their last breath of life) o_o…..they dipengsankan …oh… I mean poison to death cause of heavy intake of …if I’m not mistaken is chloroform ( it use to pengsankan animal o even human)…I can imagine they struggle to death…poor ratty…Anyway..the show must go on….First of all, we prepare all the apparatus dissecting set ( I have a set of it!.....Come my house n TRY it!!! wahaha), wear glove, mask(but I forget to bring, so I doin witout mask…make me look like very pro,haha)…and dissecting tray n some pin…
We take them n put on the tray, betulkan them in right post(position stand by to be operated) then…Stretch the rat n PIN the 4 edge(leg)…Take position n cut the skin all the way long from the chin till the penis O.O ( it a male, as a bio student must be pro not shy shy, the fact: male have less fat or adipose tissue so is easier to observe the organ n nerve system) …Then stretch the skin to separate the flesh n the skin by a thin layer of membrane… then pin it…then cut the abdomen n u can see the content of abdominal cavity of rat in situ. Got liver ,stomach, spleen intestine, duodonum ,pancreas, kidney colon, caecum ileum, rectum ,pundi kencing and even testical o.o .Cool le….then we submerge it in water so that the organ Float n make us easier to move the organ n search for the nerve…After search liao, the we cut off the stomach along till rectum.. then throw it away…Next, we cut off the ribs cage so we can observe the Visera toraks… And then….THE END.. We wash the rat n submerge in formalin for next exp(observe the heart n others, submerge in formalin so tat the blood will clot n easy to observe n cut the heart off)….The fact:Its smell bad cause it is internal organ, keep inside body witout exposing to environment.
