Study Notes
Fluid and Electrolyte Balance in the Body
- Water intake must balance water output to maintain proper hydration
- Sources of water intake include ingested fluid, solid food, and metabolic water
- Water output occurs through urine, feces, insensible losses, and sweat
- Thirst is triggered by a decline in plasma volume or an increase in plasma osmolality
- Obligatory water losses include insensible water losses and water in feces
- Antidiuretic hormone (ADH) regulates water reabsorption in the collecting ducts
- Factors triggering ADH release include fever, sweating, vomiting, and blood loss
- Dehydration causes negative fluid balance and may lead to hypovolemic shock
- Hypotonic hydration results from excessive water intake, leading to cellular overhydration
- Edema is an abnormal accumulation of fluid in the interstitial space
- Electrolytes, especially sodium, are crucial for neuromuscular excitability and fluid balance
- Aldosterone regulates sodium reabsorption in the kidneys and is triggered by the renin-angiotensin mechanism
