What are the 2 categories of Body Fluids
|
Intracellular
Extracellular |
|
|
Intracellular fluids are found where?
|
Inside the cells
|
|
|
Extracellular fluids are found where?
|
Outside the Cells
|
|
|
What are the 2 types of Extracellular fluids?
|
Intravascular and Interstitial
|
|
|
What is Intravascular fluid?
|
Fluid inside the Blood Vessels..(essentially it is plasma)
|
|
|
What is interstitial fluid?
|
(extracellular)
Fluid outside the cells. Is essentially the fluid that the cells float in. It surrounds the cells |
|
|
What keeps the Intracellular in and the extracellular out?
|
Membranes of cell walls.
|
|
|
Solute
|
Substance that is dissolved in a solution.
|
|
|
Solvent
|
The Solution that the solute is dissolved in.
|
|
|
Permeability
|
The ability of a substance (molecule) to pass thru a membrane.
|
|
|
Semi-permeable
|
Membrane that allows some substances to pass thru and others not.
|

What is the major regulator of fluid?
|
Sodium

|
What is Serum Osmolality?
|
Serum Osmolality is a measure of the solute concentration of the blood. The particles included are sodium ions, glucose, and urea.
|
|
|
What contributes to serum osmolality?
|
sodium
|
|
|
What maintains osmotic pressure?
|
Chloride
|
|
|
Calciums role?
|
Stabilizes cell membrane, transmits nerve impulses, contract muscles(esp heart), coagulate blood, form bone and teeth.
|
|
|
Bicarbonate
|
Need the significance of this.
?????????????????? |
|
|
What are the Extracellular Electrolytes?
|
Sodium, Chloride
Calcium, and Bicarbonate |
|
|
What are the Intracellular Electrolytes?
|
Phosphorus, Potassium, Magnesium
|
|
|
Phosphorus role?
|
Energy Metabolism
|
|
|
Potassium role?
|
Regulates cell excitability, nerve impulse conduction, muscle contraction and myocardial membrane responsiveness, intracellular osmolality
|
|
|
Magnesium role?
|
Needed for enzyme reaction, neuromuscular contraction, normal functioning of the nervous and cardiovascular function.
|
|
