Study Notes
Electrolytes
- Electrolytes are ions that carry an electric charge.
- They are categorized as anions (negative charge) or cations (positive charge).
- Anions move towards the anode (positive electrode) in an electric field.
- Cations move towards the cathode (negative electrode).
Electrolyte Functions
- Volume and osmotic regulation: Sodium (Na+), Chloride (Cl-), Potassium (K+)
- Myocardial rhythm and contractility: Potassium (K+), Magnesium (Mg2+), Calcium (Ca2+)
- Enzyme activation: Magnesium (Mg2+), Calcium (Ca2+), Zinc (Zn2+)
- ATPase ion pumps: Magnesium (Mg2+)
- Acid-base balance: Bicarbonate (HCO3-), Potassium (K+), Chloride (Cl-)
- Blood coagulation: Calcium (Ca2+), Magnesium (Mg2+)
- Neuromuscular excitability: Potassium (K+), Calcium (Ca2+), Magnesium (Mg2+)
- ATP production/use from glucose: Magnesium (Mg2+), Phosphate (PO4-)
Electrolyte Concentration Regulation
- The body maintains precise electrolyte concentrations.
- Complex systems monitor and regulate electrolyte levels.
