Web1 aug. 2002 · In plasmolysed leaf cells of C. comosum the AF network formed underneath the plasmalemma might protect against shearing possibly through an analogous mechanism like the contraction of stress fibres. A similar role has been also attributed to the cortical AF network formed in Dictyostelium hyperosmotically stressed cells ( Aizawa et al ., 1999 ). WebDiabetes Insipidus: Hyperosmotic Contraction; Individuals with Diabetes Insipidus excrete a urine that is more dilute than the ECF, causing relatively more loss of water than solutes from the ECF and thus a rise in ECF osmolarity. Because ECF osmolarity rises compared to that of the ICF, water moves from the ICF to the ECF. 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. rainbow parchmentboard natural
