Fluid, Electrolyte, A/b Balance Flashcards
ECF includes
Interstitial fluid
Plasma
Other body fluids
ICF
Cytosol
The ionic concentrations and ph of these fluids are as important as?
Their absolute quantities
If concentration of CA+ and K+ in ECF become too high…
Cardiac arrhythmias develop and death can result
Low pH is dangerous bc
Hydrogen ions break chemical bonds, change the shapes of complex molecules, disrupt plasma membranes, and impair tissue functions.
Stabilizing the volumes, solute concentrations, and pH of the ECF and ICF involves
Fluid balance
Electrolyte balance
Acid-base balance
Define fluid balance
When the amount of water you gain each day is equal to the amount you lose to the environment
Define electrolytes
Ions released when inorganic compounds dissociate
Electrolyte balance primarily involves
Balancing the rates of loss by kidneys
Acid-base balance
Is when the production of hydrogen ions in the body is precisely offset by their loss.
Preventing a decrease in pH is the primary problem because?
Your body generates a variety of acids during normal metabolic operations
How does the kidney prevent a decrease in pH
By secreting hydrogen ions into the urine
And
Generating buffers that enter the bloodstream
The secretions that prevent low pH take place?
In the distal segments of the distal convoluted tubules and along collecting system
The lung also play a role by eliminating CO2
