Body Fluid Compartments
This is the total amount of water contained in the human body.
What is Total Body Water (TBW)?
This electrolyte helps maintain fluid balance and blood pressure and supports nerve function.
What is sodium?
This type of membrane transport does not require cellular energy (ATP).
What is passive transport?
Unlike passive transport, this type of transport requires cellular energy.
What is active transport?
Of diffusion, osmosis, filtration, and active transport, this is the only mechanism that requires ATP.
What is active transport?
This fluid is found inside the body's cells and makes up about two-thirds of total body water.
What is Intracellular Fluid (ICF)?
This electrolyte is especially important for muscle contraction and heart function.
What is potassium?
This process moves particles from an area of higher concentration to an area of lower concentration.
What is diffusion?
The energy molecule required for active transport is abbreviated this way.
What is ATP?
Approximately what percentage of body weight is total body water (TBW).
What is approximately 50-70%?
This fluid is found outside the cells and makes up about one-third of total body water.
What is Extracellular Fluid (ECF)?
This electrolyte supports muscle contractions and is involved in nerve signaling and bone health.
What is calcium?
This process involves the movement of water across a selectively permeable membrane toward the side with the higher solute concentration.
What is osmosis?
What is the sodium potassium pump?
Which body fluid compartment contains approximately 40% of body weight?
What is Intercellular fluid (ICF)?
This ECF compartment is fluid found between cells and accounts for about three-fourths of ECF.
What is Interstitial Fluid?
This electrolyte supports muscle and nerve function and is involved in energy production.
What is magnesium?
This process moves water and small solute through a membrane because of a pressure difference.
What is filtration?
For each ATP used, the sodium-potassium pump moves this many sodium ions out of the cell.
What are 3 sodium ions?
This condition occurs when the body has an abnormally low sodium level.
What is hyponatremia?
This ECF compartment is the fluid found within blood vessels and accounts for about one-fourth of ECF.
What is Plasma (intravascular fluid)?
This negatively charged electrolyte works with sodium to maintain fluid balance and also supports digestion.
What is chloride?
Oxygen and carbon dioxide moving across a cell membrane are examples of this passive transport mechanism.
What is diffusion?
For each ATP used, the sodium-potassium pump moves this many potassium ions into the cell.
What are 2 potassium ions?
This electrolyte imbalance can cause dangerous cardiac dysrhythmias and is particularly associated with muscle weakness and ECG changes.
What is hyperkalemia?
