HEADLESS COCKROACHES & HEADLESS CHICKEN

I have a friend who is a surgeon- one who operates on human bodies in the operation theatre
to fix body parts that have malfunctioned. When she was studying to become a surgeon, before they could operate on human bodies, they first operated on insects and animals, because one CANNOT make any mistake when operating on human bodies, and therefore, they had to first try on animals and insects instead of human beings.

This was what she found out.

1) If you cut off the head of the cockroach, the cockroach can still go on crawling and continue to live for 3days!

So there was once, her teacher told them to kill a chicken, and apparently to kill a chicken, you have to take it by its neck and swing it until the neck breaks. (my friend is 40 over years old, so she had a very primitive way of killing chickens). So all the students took the chicken by the neck and swing it and when the neck broke, the chicken fell off and all the headless chickens instead of dropping dead, were found walking around headlessly, with blood spewing off their necks!

2) Hence, if you chop off the head of the chicken, the chicken can still go on walking for 3 hours, with blood spewing off its neck.

HOW COME?
The reason why the cockroach can live for 3 days without its head is because the breathing mechanism of the cockroach isn't in its head. And since it doesn't need a lot of nutrients to survive, it can still live for 3 days without its head.

As for the chicken.. since it can still stay alive for 3hours without its head, u can tell that it doesn't use its brain a lot!

I just thought these facts are really interesting and hilarious!

Recently I have been watching the korean drama on channel U over the weekends, from 730-930pm. It is a show about surgeons who operate on the patients. As I was watching the show today, I was thinking it is like soooo amazing that the doctors can cut open our skin to reveal the organ beneath the skin- make the necessary changes to our organ, and sew our skin back such that we don't go around walking with a hole in our body.

But how did they do that? Our smallest organ is still as big as our fist(!) so doesn't that mean the wound should be quite BIG, but the stitches on anyone who has had operation doesn't seem to be HUGE. Just find it quite interesting and I am curious..
