Hey, Thanks for the reply
However in this scenario if I add salt into intravascular compartment, wouldn't that make it more hypertonic, so shouldn't water from outside come in, instead. Why have you stated the opposite? Did I missunderstand something.
EDIT: Oh wait are u saying? If I add salt to blood vessels, water from red blood cells for example would come out increasing intravascular compartment, then this excess water would go out of the intravascular compartment due to increase hydrostatic pressure inside the vessels, so you lose some water from crystalloids.
