Flash cards for fluids and electrolytes
# Term Definition
1 What chief electrolyte of the ECF Na+ Sodium
2 What is the major cation of ICF K+ Potassium
3 What is the most abundant Ca+ Calcium
electrolyte in the body
4 Where is most of the cation Within body cells such as the heart, bone, nerve,
magnesium found and musscle tissues
5 What is the second most Mg+ Magnesium
important cation in the ICF
6 What is the chief extracellular ion Cl- Chloride
ECF
7 What is the major chemical base HCO3 Bicarbonate
buffer within the body
8 What the the major anion in body PO Phosphate
cells and acts as a buffer in both
ICF and ECF
9 What is Na function Controls and regulates the volume of body fluid
Maintains water balance Primary regulator of
ECF volume Influences ICF volume Participates
the the generation and transmission of nerve
impulses Essential electrolyte in the NaK pump
10 What is K function Chief regulator of cellular enzyme activity and
cellular water content Plays a vital role in
transmission of electric impulses, in the heart,
nerves, skeletal, intestinal, lung tissue Protein
and carbohydrate metabolism and cellular
building Assists in regulation of acidbase
balance by cellular exchange with H+

# Term Definition
11 What is Ca function Necessary for nerve impulse transmission and
blood clotting Catalyst for muscle contraction
Needed for vitamin B absorption and for its use
by body cells Acts as a catalyst for many cell
chemical activities Strong bones and teeth
Determines the thickness and strength of cell
memebranes
12 What is Mg function Important for the metabolism of carbohydrates
and proteins Important for many vital reactions
involving enzymes protein and DNA synthesis
DNA and RNA transcription translation of RNA
Maintains normal intracellulr levels of K
Maintain electrical activity in nervous tissue
membranes and muscle membranes
13 What is Cl- function Acts with sodium to maintain the osmotic
pressure of the blood Role in the body's
acidbase balance Important buffering action
when O2 and CO2 exchange in RBC Essential for
the production of hydrochloric acid in gastric
juices
14 What is HCO3 function Essential for acidbase balance bicarbonate and
carbonic acid constitue the body's primary
buffer system
15 What is PO- funciton Maintains the body's acid base balance Involved
in important chemical reaction in the body
Important in cell division and for the
transmissio of hereditary traits
16 How is Na excesses eliminated Kidneys and small amounts lost in feces and
perspiration
17 What are the leading food bananas peaches oranges broccoli and potatoes
sources for K
18 How is K excreted Kidneys deficits occur if potassium excretion in
excess without being replaced simultaneously
19 What is the average daily Adults require about 1g Children and pregnant
requirement for Ca in adults and women by body weight 1500mg day for older
children adults
