Study Notes
Nerve Function
- Sodium and potassium are essential for generating and transmitting nerve impulses.
- Imbalances in these electrolytes can lead to symptoms like altered mental status, muscle weakness, or paralysis.
Muscle Contraction
- Calcium and magnesium play critical roles in muscle contraction and relaxation.
- Disruptions in calcium or magnesium levels may cause muscle cramps, weakness, or tetany.
Acid-Base Balance
- The kidneys, lungs, and blood buffers collaborate to maintain stable pH levels in the body.
- Electrolytes, notably bicarbonate, are integral in the acid-base balance process.
Blood Pressure Regulation
- Blood pressure is influenced by fluid volume and electrolyte concentrations.
- Mechanisms like the renin-angiotensin-aldosterone system (RAAS) regulate blood pressure in response to electrolyte levels.
Cellular Function
- Electrolytes are involved in various cellular processes, including nutrient transport, enzyme activity, and protein synthesis.
- Proper electrolyte balance is crucial for maintaining overall cellular health and function.
