WebWhen the blood osmolality increases, or more solutes there are in the blood, this causes water to be drawn into the blood from the interstitial compartment. This means the body losses water, dehydration, and causes increased pressure in the vein, hypertension. How does alterations in blood osmotic pressure cause edema? WebYour body is constantly monitoring serum osmolarity. Serum osmolarity is the measurement of the concentration of solutes in your blood serum (which is your blood minus the cells and larger proteins). Normal human serum is around 300 milli-Osmole/Liter (Osmoles represent adding up all of the solutes into one measurement).
