Biology class

Current music: Lia - Horizon (Omega Force~Updated)

Today, during Biology class, we dissected a frog.

Yep, frog as in FROG. The pale-green, insect-eating, jumping creature.

It was interesting actually, though I thought it was disgusting at first. I actually touched a frog <_< (finally)

Anyway, I joined Crystal, Shamin, Hareesh, Fabian and Zainul's group in our little frog-dissecting adventure.

First of all, the frog was in a huge jar. Mdm. Grace moistened some cotton wool with chloroform and put it in the jar. (The chloroform is for the purpose of making the frog faint/sleep) <--the frog is still alive, you know.

***A scene before the experiment***
Mdm. Grace: All of you need to use the scissors to cut open the frog's skin...
Brian: Using the normal scissors or the zig-zag one?
Mdm. Grace: The normal one.
Cynthia: Brian, the zig-zag scissors are for decoration-lah!

Anyway, as we started the experiment, we used pins the pin down the frog. A pin was pinned at 45 degree angle on each limb of the frog, with the stomach facing us.
(The way the frog was pinned reminded me of the way I slept (kidding) or the way a flying squirrel opens its "wings").

Then, we used forceps to pull up the skin a bit so that it is easier to cut them with scissors. The skin was first cut from the genital area to just below the mouth (poor frog).

After that, the skin was stretched out and pinned to the tray on each side (like wings, y'know?) Below the skin was a greyish under-layer. We cut that too and then we saw it. The respiratory system of the frog.

There were two cute lil lungs and a tiny heart that was still beating strongly. The frog's liver was bluish in colour.

We were asked to remove ONE lung so that was what we did xD After we "plucked" out the lung, it immediately shrunk, as if the air had gone out of it. There was an obvious difference in size between the removed lung and the one still in the frog.

Afterwards, with the help of scissors, knives and forceps, the heart was removed. (really, poor frog) Even after it was removed, the heart was still beating. This was because the heart is and organ that is myogenic (is that how you spell it?)

I asked Shamin to put the heart on the palm of my hand (and mind you, we were all wearing gloves). The feeling of having a small, beating heart on you palm was...indescribable... Some of the girls came near me and I showed them the heart. Some of the screamed and inched away.

Waaah...the feeling was like...I was dominating the world(kidding again). I experienced something new...

Although we were only required to remove the lungs and heart, we even proceeded to remove the intestines, livers and other organs.
When it was time to clean up, we put back the organs into the frog and put the corpse of the frog into a plastic container <---it's "coffin".

We payed our last respects to the frog xD.
Then, Mdm. Grave led Brian, Crystal, Tung and I to dump away the corpses...

We had to walk through the canteen. The evil Brian showed the container to every student passing by. (And they were EATING at that time xD)

We then dumped the rubbish bag outside. When we went back to the canteen...

Mdm. Grace: Ei, you don't throw away your gloves ah?! (All of us threw away our gloves, except Brian)
Brian: Ui?! *rushes outside to throw the gloves...that joined the frog)

Crystal and I walked back up to the canteen while Brian and Tung pretended to sneak away from school. Mdm. Grace voiced out a funny "EII!!!" and the two boys laughed and came back up xD

All in all, it was a great (and freaky) experience.

...I wonder if we're gonna dissect a HUMAN in the future *ponders*

Later~!
