fluids are vital to the body's ability to maintain its temperature within a safe range. TWO factors account
for the ability of fluids to keep us cool. - First,
-water has a relatively high capacity for heat; in other words, it takes a lot of energy to raise its
temperature.
-Because the body contains a lot of water, only prolonged exposure to high heat can increase body
temperature.
Second,
-body fluids are our primary coolant.
Body fluids are composed of - water and solutes
FOUR Critical functions of water to life: - Solubility and transport
Fluid found between the cells within tissues and organs of the body. - Tissue fluid
The fluid portion of blood that carries the blood cells - Plasma
lean tissue - -non-fat body tissue such as muscle, bone, and internal organs
Minerals, such as salt, that dissolve in water are called - Electolytes
-A substance that flows freely.
- Have the ability to conform to the shape of the container that holds them. - Fluids
functions of electrolytes - 1)help regulate fluid balance (osmosis)
,2)help nerves respond to stimuli (Action Potential)
3)signal our muscles to contract
Liquid portion of blood is called _____ it is a fluid, but it is not the same as water. - plasma
Two-thirds, most of our water, of body's fluid is - Intracellular fluid
The remaining one-third of body's fluid is called - Extracellular fluid
intra - within, inside
inter - between
extra - outside
Solute - A substance that is dissolved in a solution.
(A powder)
Solvent - In a solution, the substance in which the solute dissolves.
(The water)
Potassium in blood is called - Kalemia
Sodium in blood is called - Natrium
extracellular fluid include - -Tissue fluid (interstitial fluid)
, -Intravascular fluid (plasma)
The body fluid composition of tissue varies by - -Tissue type
lean tissues (muscle) have higher fluid content than fat tissues
-Gender
males have more lean tissue and therefore more body fluid
-Age
as we get older, we lose water.
HPO4 2- - -Phosphorus in form of hydrogen phosphate
K+ - Potassium
Na+ - Sodium
CL- - Chloride
In intracellular fluid, ___ and ___ are the predominant elestrolytes - K+ and HPO4 2-
In extracellular fluid, ___ and ___ predominate. - Na+ and CL-
Water follows what? - salt
if someone has not water, we will give them ____ - Electrolytes
