Fluids And Electrolytes Flashcards
Extracellular fluid (ECF)
Found outside the cells and accounts for 1/3 of the total body fluid
Intravascular fluid or plasma
Accounts for approximately 20% of ECF and is found in the vascular system
Other components of ECF
The lymph and transcellular fluids
Transcellular fluids are
Cerebrospinal, pericardial, pancreatic, pleural, intraocular, biliary, peritoneal, and synovial fluids
Interstitial fluid
Accounts for 75% of the ECF and surrounds the cells
Intercellular fluid contains
Oxygen, electrolytes, and glucose
EFC is the transport system that Carries….
Oxygen and nutrients to and waste products from body cells
Interstitial fluid transport…
Wastes from cells by the way of the lymph system as well as directly into the blood plasma through capillaries
Water is vital to health and normal cellular function serving as
A medium for metabolic reactions in cells
A transport for nutrients waste products and other substances
A lubricant
And insulator and shock absorber
A means of regulating a maintaining body temperature
Electrolytes
Sodium chloride breaks up into one ion of sodium Na+ and one ion of chloride CL- these charges particles are called electrolytes
Cations
Have a positive charge
Eg- sodium, potassium, calcium, magnesium
Anions
Have a negative charge
Eg- chloride, bicarbonate, phosphate, and sulfate
The principal electrolytes in ECF
Sodium, chloride, and bicarbonate
Primary cations and anions of ICF
Cations: potassium and magnesium
Anions: phosphate and sulfate
Intracellular fluid (ICF)
Found within the cells of the body. Constitutes 2/3 of the total body fluid in adults
