Dissection of Rat (Limited to above 15)




The innocent little cuties in cage.


Harmful chloroform was used to kill the rats.It's harmful as ur genes will be mutated after touching it.


Can't see? Go here - YOUTUBE
This was what happened when u got no expriment of catching the rat and putting it in the beaker.


The rat was fainted/ dead after it was put in the beaker with chloroform.


Nailed on the polisterene.


Cut and open up the outer skin layer.


The look after the outer skin layer had been removed.This is a male species.


Cut up the muscle tissue layer.


Nailed the mucle tissue layer.Observing the digestive system of mammal. (same as human 1)


Scattered the organs and observed carefully of them.There are liver,kidney,stomach,duodenum,ileum,colon,caecum,rectum,...


Cut out the rib cage as next step.


This is what u can see after cutting the rib cage- a heart and the lungs.


A wider look of the organs...


Cut up the throat and cut out the trachea to observe the respiratory system.


The respiratory system


The closer look of the system.


The pointed,white colour gland which right above the kidney - adrenaline gland

Due to the time problem,we were unable to post mortem the rats' brains to look at the brain and its system.

Sorry for causing any uncomfortable feeling...just want to share what I experienced when I conducted the expriment.
