Study Notes
Water and Electrolyte Balance and Imbalance
- Total body water in a 70 kg adult is between 60% and 70% of total body weight, which equates to 36-49 liters.
- Body water is divided into two compartments:
- Intracellular fluid (ICF): This is the fluid within cells and makes up approximately 50% of total body water (35 liters).
- Extracellular fluid (ECF): This is the fluid outside cells and accounts for the remaining 50% of total body water.
Abnormal Water and Electrolyte Metabolism
- There are two types of abnormalities:
- Fluid Imbalance: This refers to imbalances in the total amount of fluid in the body.
- Electrolyte Imbalance: This refers to imbalances in the concentration of electrolytes in the body.
