Develop a model of a feedback system dotpoint

[exhausted]

I used this diagram in my trials which asked to draw a negative feedback mechanism, but i didnt get full marks for it and im unsure of why?
So if anyone has a better one/has any suggestions please help me out because i dont know where i went wrong

EDIT: Ive just made a new diagram, is that one better than the original? (new one is the one with red and blue arrows with yellow star indicating homeostasis)

I'm not 100% sure why it wouldn't, it might be because it doesn't mention homeostasis? Are you able to get a copy of the marking criteria?

Either way, this is the one I use, sorry if it's hard to read haha

here's mine: I think you may have lost marks on not writing out "effector". Also I feel the effector is vasoconstriction/dilation rather than the response.  for example vasodilation---> heat radiates off skin quickly since more blood comes to surface of skin ---> body temp decrease
as well, sometimes they want you to give different responses (I sent a flowchart for my teacher to mark before, and I lost a mark because I did vasoconstriction/dilation + not sweating/sweating, and she said she wanted a different type of response e.g. for body temp decreasing I could've wrote shivering or something).

I just made this one up, is this better?

Yeah I'd say so!
