Study Notes
Electrolyte Balance and Functions
- Electrolytes control water movement between intracellular and extracellular fluid, maintaining osmolarity.
- Electrolytes help regulate blood pH, act as enzyme cofactors, and facilitate electrical signal transmission in the body.
Movement of Electrolytes
- Electrolytes move based on concentration and charge gradients.
- Charge distribution is crucial, with positively charged ions moving towards negatively charged areas and vice versa.
- Milliequivalents per liter measure electrolyte concentration, accounting for charge.
Important Electrolytes
- Extracellular electrolytes: sodium, chloride, calcium, and bicarbonate.
- Intracellular electrolytes: potassium, magnesium, phosphates, and sulfates.
Specific Electrolytes
Sodium
- Most abundant extracellular ion, crucial for osmolarity balance.
- Excessive sodium intake is common in diets, regulated by hormones like aldosterone and atrial natriuretic peptide.
- Functions include depolarization in electrical activity and action potentials.
Chloride
- Balances sodium in extracellular fluid to maintain a neutral charge.
- Functions in stomach acid production and kidney processes like the chloride shift.
- Moves easily between compartments to balance charges.
Potassium
- Most abundant intracellular cation, essential for repolarization and establishing resting membrane potential.
- Balances movement of hydrogen ions to maintain charge equilibrium.
- Disruption in potassium levels can lead to acid-base imbalances.
Bicarbonate
- Generated in the presence of CO2 and water, crucial for acid-base balance as a buffer.
- Regulated primarily by the kidneys, important in various bodily compartments.
- Converts excess hydrogen ions into carbonic acid for elimination.
Calcium
- Most abundant electrolyte in the body, crucial for bone structure and teeth.
- Functions in nervous system signaling, muscle contractions, and blood clotting.
- Regulated by hormones like parathyroid, calcitonin, and calcitriol.
Magnesium
- Primarily an intracellular cation, acts as a cofactor for enzymes related to metabolism and neuromuscular activity.
- Essential for synaptic activity and mood/neurological disorders.
Phosphates
- Structurally important in the phospholipid bilayer, essential for ATP, DNA, and RNA formation.
- Intracellularly buffers fluid acidity, regulated by hormones like parathyroid hormone and calcitriol.
