Overview

In relation to blood pressure regulation, what do you think is meant by short-term
and long-term?

I think short-term is related to minor changes and long term have to do with more
major changes.




Sort the following into whether they will a ect short-term blood pressure, long-term
blood pressure, or both.

What determines blood volume?

The amount of sodium chloride (NaCl) in the extracellular uid.
The concentration of sodium chloride (NaCl) in the extracellular uid.
