Homeostatic Process

[Nicolodn]

In the homeostatic process of plasma osmolarity regulation, what does the kidney
act as?
a. An effector
b. The integrating centre (would be the hypothalamus, not kidney)
c. The set point (I know it isn't, since set point is the range/limits that are maintained for the body)
d. A regulated variable
e. A stimulus (I know it isn't, since stimulus would be the change of osmolarity of the plasma)

Antagonistic control mechanisms?-->
b. Two effectors with opposite effects
c. Only delayed responses
d. An effector that can increase or decrease output
e. A lower threshold for the stimulus than tonic control mechanisms

THanks.

what about to put it into one threas?
2b

[Nicolodn]

Okay, sorry.

What would the answer to the first q be?
..and do you mean for the 2nd question the answer is b)?

Thanks.

[BeyazRus]

I think that answer of the second question is a.
Because the definition of "Antagonist" is; "One who opposes and contends against another"

[JackBean]

actually, there is no a

[Nicolodn]

Anybody know the answer to
Q. In plasma osmolarity regulation, the kidney acts as the....?

[JackBean]

what about d?

[Nicolodn]

I was choosing between a) or d) .
I thought that it wouldn't be d) because the regulated variable would be the plasma osmolarity. and I'm not sure why a) wouldn't be.

ALSO, someone please help me out in my other post- "Cell Membrane" which is also in the CELL BIOLOGY forum. THANKS.

[JackBean]

yeah, I think that's a good point...

you see, if you wrote that in your first post, you could have the answers on Saturday...
