The concentration of electrolytes in intravenous (iv) infusion is typically 270-300 milliosmoles per liter (mosm/l). human blood is about 300mosm/l. why is it necessary to have an iv that is near isotonic with the blood?

Explanation:

It is necessary to have an IV that is near isotonic with blood so that the concentration of multiple different molecules in our blood does not change. If it's not isotonic then the cells begin  to contract because they are starting to lose water.

the match lol

after receiving a stimus, the sensory receptors send(s) signals to the appropriate area of the body.  

the must be sensory neurons.  

hope its .
