👉 The "Counts Fluid" refers to the measurement of various components within the body's fluid compartments, which are categorized into intracellular fluid (ICF), interstitial fluid (ISF), and blood plasma. Each compartment contains different concentrations of electrolytes like sodium, potassium, chloride, bicarbonate, and water. The ICF, primarily found inside cells, typically has a higher concentration of potassium (K+) and phosphate (HPO4^2-) compared to sodium (Na+). Conversely, the ISF, surrounding cells and tissues, has a higher concentration of sodium (Na+) and chloride (Cl-) relative to potassium. Blood plasma, the fluid component of blood, contains a balanced mix of these electrolytes and is crucial for maintaining homeostasis. The total fluid volume, including all these compartments, is tightly regulated by the body to ensure proper cellular function and overall health.
