Study Notes
Body Water Content
- Infants have the greatest body water content due to their high water requirement for growth and development.
- Old age persons have the least body water content due to decreased muscle mass and increased fat deposition.
Adult Body Water Content
- Normal adult females have less body water than normal adult males due to a higher percentage of body fat.
- The total body water in an adult male person weighing 70 kg is approximately 42 liters.
- The percentage of total body water in an adult person is around 55-60%.
Fluid Compartments
- The intracellular fluid compartment represents 2/3 of Total Body Water.
- The major anion in intracellular fluid is phosphate.
- The major cation in extracellular fluid is sodium.
Ion Concentrations
- Compared to intracellular fluid, extracellular fluid has a higher sodium ion concentration, lower potassium ion concentration, higher chloride ion concentration, and lower phosphate ion concentration.
Plasma and Interstitial Fluid
- Plasma and interstitial fluid are almost identical in composition except for a higher concentration of proteins in plasma.
Body Fluid Volumes
- The lymphatic fluid volume cannot be directly determined with a single indicator.
Osmosis and Filtration
- The movement of water from an area of greater concentration to an area of lower concentration is called osmosis.
- The transfer of water and dissolved substances from a region of high pressure to a region of low pressure is called filtration.
- The channel protein responsible for osmosis is aquaporin.
- The force responsible for filtration is hydrostatic pressure.
