Plasma levels - correct me if i'm wrong

[bossman_1986]

where exactly is the sciatic nerve located? and what are the chances of hitting it?

Jay,

Firstly your thinking is faulty.
There are no plasma concentrations. It is merely the substance in which the other three cellular elements (rbc’s, wbc’s and platelets) circulate.

So essentially plasma is the bloodstream, making Roid’s statement quite true.
The only EXCEPTION, or time we see significant concentrations is when wbc’s are recruited for battle.
-----------------

I will also add that absorbtion is relative to the amount of capillary beds in a given area. Areas with high capillary density will increase the rate of absorbtion because capillaries are only one cell thick and are direct access to the blood stream. The larger the muscle expose to the injectable the greater the absorbtion based on the muscle exposed.
If that makes sense.

VERY TRUE!
But I think you meant ‘faster’ not ‘greater’ absorption, as eventually all absorption will be complete, but as you said prior more caps incr. the rate.
