Despite this perturbation, mean arterial blood pressure was maintained through 12 h with a slight but nonsignificant fall thereafter (Table 1A). WebHow come in some cases, like hyperosmotic volume contraction hematocrit doesn't change (because fluid moves out of the RBC), but in other cases like hyperosmotic volume expansion hematocrit decreases. Wouldn't water move out of the RBC in this case too? I'm confused about which situations that this principle applies to.

WebA special type of passive transport is the movement of water across a membrane, or osmosis.By definition, osmosis is the diffusion of water through a selectively permeable membrane from an area of high water potential (low solute concentration) to an area of low water potential (high solute concentration).
