Discussion of all aspects of cellular structure, physiology and communication.
Biology is eas... Well, except anatomy... The great thing about it is that it all makes sense
"As a biologist, I firmly believe that when you're dead, you're dead. Except for what you live behind in history. That's the only afterlife" - J. Craig Venter
Hmm, sounds like what i did last week for one of my practicals haha.
We tried to ferment grape juice with yeast (S.cerevisiea) - and did Brix to check on the sugar content too. Pretty simple but fun i must say =D
Thank goodness i dun think we got our "wine" contaminated by Acetobacter or my sulphur reducing bacteria haha (cos our lead acetate paper pasted inside our flask didn't turn black) =).
Guess you're wrong...I learned anatomy when I was in 11th class and I found that anatomy is the most interesting part of biology...beside it's quite 'easy'.. (well it's until now...and that's why I really active in human biology site )
Q: Why are chemists great for solving problems?
A: They have all the solutions.
Anatomy? Easy?! You don't need to memorise all the 206 bones and 665(i think) muscles in the human body... All you need to memorise is structure and fiziology of each organ. Sure, anatomy seems easy... But here is the kind of question i need to know for the national lot(i am really proud since i am the only one who answered it correctly at the lot this year):
Name all the kinds of cells in the liver! Can you?
The most abundent cells in the liver are the parenchimatic(round) ones: hepatocytes(commonly reffered to as liver cells)
Other cells(non-parenchimatic=with other formes than round):
-the endotelial cells of the sinusoid cappilaries
- PIT cells
- ITO cells
- Kupfer cells
- epitelial cells of the biliar ducts(not sure about the translation here)
What be too tell you what each of them does(Yeah, i know i am showing off )?
It took me a very long time to learn this kind of stuff... But this is the kind of questions they ask at IBO
Go right ahead
Interesting that the liver has epithelial cells.
P.S. what's the UAG in your sig stand for?
Living one day at a time;
Enjoying one moment at a time;
Accepting hardships as the pathway to peace;
PS: the liver is made out of epithelial cell, you know
Here is what i remember...
Kupfer cells are also in the capilaries... They belong to the mononuclear fagocytosis sistem(a defense system)
ITO cells- my personal favourites.. Their number increases significally in hipervitaminose A. When there is an overload with lipids or alcohol these cells turn into something called miofibroblasts that contribue to the fibrosation(right term?!) of the liver by producing colagen and also by producing some chemical substances that favourise fibrosation
PIT cells- they are T limfocytes(T natural killers). They stick to the glicocalix of the hepatocytes. Their number increases in inflamations
Epithelial cells don't do anything, they just stand there
