1. :* Cerebral edema is extracellular fluid accumulation in the brain. 2. The composition of HTK is similar to that of extracellular fluid . 3. Sodium is the most prevalent metallic ion in extracellular fluid . 4. These include intracellular fluid; extracellular fluid ; ocular fluids. 5. They remain apposed to neurons and regulate the extracellular fluid . 6. These extracellular fluids then drain into blood vessels, causing a rehydrating effect. 7. Osteoblasts separate bone from the extracellular fluid by tight junctions by regulated transport. 8. Pinocytosis is used primarily for the absorption of extracellular fluids ( ECF ). 9. This causes water to move out of the cells, increasing extracellular fluids . 10. The flow of sodium ions across epithelia affects osmolarity of the extracellular fluid .
