Heeeelppp pleassseee!

Is this a homework question? We will help you, but you have to make an effort. Do you have anything written down yet, or do you want me to just hand over the answers?

Can you just tell me the answer :)
I need the 4 functions and their significance please... ----

Tell me something. I really, honestly want to know. Why should I do your homework for you? Why should I just hand over answers to you?

Wow relax!
I couldn't find it on Google... but thanks anywayyyss >.<

Pinkey, I did my homework without other people giving me the answers and, guess what... I KNOW this now. Remember you can't take us with you to your exam.

If you would give me an idea of what you have already, I would love to help you. But I don't cheat, and this is considered cheating in my book.

One way that might help you fing/guess the answers, ask yourself what would happen if there wasn't blood.

what would happen if there wasn't blood.

You would DIE!! :eek:

Exactly! :D

So, one should by this at least get some guesses (even if they don't know its functions) right.

Okay, two "guesses" think about infection and oxygenation
