60% - ANSWER what percentage of a healthy human body is made up of
water?
1. medium for metabolic reactions with cells
2. transporter of waste products and other stuff
3. insulator or shock absorber
4. helps regulate body temperature - ANSWER what are the 4 major roles of
water in the body?
1. age: babies (70-80%) > elderly (50%)
2. sex: men > women
3. size: muscle holds more water > fat - ANSWER 3 factors that affect total
body water and how it affects it (3)
1. intracellular fluid
-in the cells, 2/3 total, has oxygen electrolytes and glucose. provides
environment for metabolic processes of cell to take place
2. extracellular fluid
-extracellular, 1/2 total, transport system that carries nutrients to and waste
products away from the cells. - ANSWER how is body fluid distributed in the
body, 2 major components and their functions
1. intravascular fluid (20%) plasma, blood
2. interstitial fluid (70%) increase -> edema
, 3. transcellular fluid (10%) CSF, pericardial, pancreatic, pleural, intraocular,
biliary, peritonial, synovial - ANSWER EFC is divided into three
compartments, what are they and give examples of each (3)
ions, electrolytes - ANSWER ICF & ECF contain _____ which are charged
particles, in the human body they're called _________
cation, anion - ANSWER a _____ is an ion that carries a + charged, _______
carries a - charge
Na+, K+, Ca2+ - ANSWER 3 cations
Cl-, HCO3- (bicarb) - ANSWER 3 anions
mEq/L, mg/100mL - ANSWER K and Na are measured in ______, Mg is
measured in _______
Na+, Cl-, HCO3- - ANSWER 3 principle electrolytes found in ECF
K+, Mg+, phosphate - ANSWER 3 principle electrolytes in ICF
osmolality - ANSWER concentration of solutes in body fluids
tonicity - ANSWER osmolality of a solution
isotonic;
-0.9% NaCl (normal saline)
