Cellular Regulation

What is Cellular Regulation?

TermDefinition
Diffusion The movement of solutes from an area of high concentration to an area of low concentration
Electrolytes Charged particles found in body fluids
Extracellular fluid (ECF) The fluid located between cells and includes interstitial and intravascular fluid
Hypertonic A solution with a concentration higher than that of blood
Hypotonic A solution with a concentration lower than that of blood
Interstitial fluid The fluid located between cells
Intracellular fluid (ICF) The fluid located inside each cell
Intravascular fluid The fluid located inside the blood vessels, excluding the fluid inside the cells in the blood vessels
Isotonic Solution that has the same osmotic pressure as the referent solution (ex plasma)
Oncotic pressure Osmotic pressure because of proteins
Osmolality The number of solutes per kilogram of fluid
Osmolarity The number of solutes per liter of fluid
Osmosis The movement of water from an area of low concentration of solutes (low osmolality) to an area of high concentration of solutes (high osmolality)
Osmotic pressure The ability of a solution to draw fluid across a semipermeable membrane
Semipermeable membranes Separation between two areas that allows movement of some fluids or solutes
Solutes Particles contained within the fluid that contributes to the concentration or osmolality of the fluid
Transcellular fluid Fluid that is in neither the intracellular nor extracellular space, and includes cerebrospinal fluid, joint fluid, and the fluid within the gastrointestinal tract
