Acid, Base and Reproductive (correct answers)
In lean adults, how much body fluid makes up the total body mass? correct answers 55-
60%
What are the 2 main 'compartments' where fluids are present? correct answers Inside
the cell (ICF)(intracellular fluid) and Outside the cell (OCF)
How much of the body is intracellular fluid (ICF) or cytosol, the fluid within cells. correct
answers 2/3
What makes up 1/3 of the fluid in the body? correct answers extracellular fluid (ECF),
extracellular fluid (ECF) correct answers outside cells and includes all other body fluids
ECF 2 main cateogories correct answers 1. interstitcial fluid
2. Blood plasma
Intersticial fluid correct answers About 80% of the ECF
occupies the spaces between tissue cells
Blood plasma correct answers about 20% of the ECF.
Fills blood vessels
Interstitial fluid is what precent? correct answers 80%
Blood plasma is what precent? correct answers 20%
Two "barriers" separate intracellular fluid, interstitial fluid, & plasma correct answers
plasma membrane and blood vessels walls.
Solute and solvent examples correct answers solute: NaCl
Solvent: Water
Fluid balance: water correct answers Because water and solutes can move across
these body compartments; there is a need to balance this flow so no compartment
accumulates solutes or water alone. Example: edema
Fluid balance correct answers the various body compartments contain the normal
amount of water and solutes
Water correct answers the largest single component in the body, about 45-70% of total
body mass in lean adults.
electrolyte correct answers an inorganic substance that dissociates into ions in solution.
, Fluid balance and electrolyte balance are ________________. correct answers
interrelated
Daily water gain and loss are each about ________ mL/day correct answers 2300
in a semipermeable membrane, water moves... correct answers from an area of high
concentration to an area of low concnetration
Osmosis correct answers Diffusion of water through a selectively permeable membrane
diffusion correct answers Movement of molecules from an area of higher concentration
to an area of lower concentration.
Water gain correct answers ingested liquids and foods and water produced by
metabolic reactions (metabolic water)
Water loss correct answers through urine, evaporation from the skin surface, exhalation
by the lungs, and defecation.
what gives us the urge to drink? correct answers An area in the hypothalamus known as
the thirst center
what happens when water loss is greater than water gain correct answers Dehydration
dehydration correct answers is a decrease in volume and an increase in osmotic
pressure of body fluids
Dehydration provides ..... correct answers signals that stimulate thirst.
Aldosterone correct answers reduces urinary loss of Na+ and Cl- and thereby increases
the volume of body fluids. Water follows ions!
Atrial natriuretic peptide (ANP) correct answers Promotes urination, Natriuresis (sodium
in urine), elevated excretion of Na+ (and Cl-) and water, which decreases blood volume.
(secreted from the heart)
The major hormone that regulates water loss is correct answers antidiuretic hormone
(ADH)
How is osmotic pressure of the body fluid stimulated correct answers An increase in the
osmotic pressure of body fluids stimulates ADH by stimulating the thirst center in the
hypothalamus
Factors that maintain water balance in the body correct answers - Thirst center in
hypothalamus
