BASIC CONCEPTS Flashcards
Ions capable of carrying an electric charge (Positive or Negative)
Participate in various metabolic activities so that it can also contribute to normal physiologic actions in the body
It is dissolved in water, thus, it is present where water is located; also contributes to the plasma osmolality
ELECTROLYTES
Ions that carry (-) charge and move toward the anode (+)
Anions
Enumerate the Ex. of Anions
Chloride, Bicarbonate, and Phosphate
Ions that carry (+) charge and move toward the cathode (-)
Cations
Enumerate the Ex. of Cations
Sodium, Potassium, Magnesium, and Calcium
What are the CLASSIFICATIONS According to the charge it carries?
Anions
Cations
What are the CLASSIFICATIONS According to its location/Distribution?
Intracellular & Extracellular
Intravascular & Extravascular
Present within the cell, specifically in the cytoplasm or cytosol (cytosol is the water component of cytoplasm)
Intracellular
Examples of Intracellular
Potassium, Phosphate
Found outside the cell, plasma or interstitial fluid
Extracellular
Examples of Extracellular
Sodium and Chloride
Inside the blood vessel → plasma
Intravascular
Outside the blood vessel → interstitial fluid/tissue fluid
Extravascular
What are the FACTORS THAT REGULATE ELECTROLYTE CONCENTRATION IN THE BLOOD?
- Diet
- Intestinal absorption of electrolytes
- Renal and skin excretion of electrolytes
- Hormonal activity
most electrolytes are derived from exogenous source (food or fluid intake)
Diet
