Works as solvent for transport
eliminates wastes through kidney, skin, lungs, and gastrointestinal tract
Assists with temp regulation
Lubricant for joints
comprises 40% of total body weight
Consists of intravascular fluid opr plasma and interstitial fluid that is between the cells and outsided the blood vessels
Large amount of K+, mg+,po4-
larger amount of Na+, hco3-, cl-, Ca+
Spacing of fluids.
1st space=
Normal distribution
spacing of fluids
2nd space
abnomal accumulation in interstitial compartment resulting in edema
what causes increased hydrostatic pressure or decreased colloid osmotic or oncontic pressure in veins?
edema, 2nd space fluid filling
spacing of fluid
accumulation in potential spaces (peritoneum, pancreas, intestines)
3rd space
process of water movement through a semipermeable membrane from an area of LOW solute concentrate to an area HIGH solute concentration.
The pulling force for water created by numbers of molecules.
osmotic pressure
What is normal serum osmolarity
What is normal serum osmolarity
normal serum osmolartiy means
the osmotic pressure of a solution
Has same osmolarity as blood plasma
isotonic fluids
what expands intravascular volume without causing a fluid shift
isotonic fluids
Pulls fluids from cells since the solution has more osmotic pressure then the interstitial fluid or intracellular fluid.
hypertonic fluids
What moves fluid into cells because intracellular fluid has more pulling power
hypotonic fluids
hypertonic and hypotoninc both occure through
moves fluid into cells because intracellular fluid has more pulling power
hypotonic fluids
movement of molecules or solute in a solution across a semipermeable membrane from an area of HIGHER concentrate to an area of LOWER concentration.
Stops when concentration is same in both areas.
O2 and CO2 diffuse across alveolar capillary membranes
The process of water and diffusable substances such as electrolytes move together across semipermeavle membranes in a response to fluid pressure.
Movement of materials across the membranes and epithelial layers of a cell by jmeans of chemical activity that allows the cell to admit otherwise impermeable molecules against a concentration gradient.
active transport
What pulls potassium into cells and sodium out of cells
Sodium-potassium pump.
enzymes along with ATP is required for?
active transport
Cells absorb what for energy
where is the thirst control center located?
often blunted response in older adults
thirst center
What responds to reduction in water
thirst control center
Causes kidneys to retain water when the hypothalamus senses low blood volume and increased serum osmolarity.
What gland secretes ADH
posterior pituitary gland
these cells of the kidney secrete renin when blood flow to glomerulus drops
juxtaglomerular cells
Renin converts what in the liver to angiotensin I.
Renin converts angiotensionogen in the liver to ?
angiotensin I.
Na+ and water retention, and K+ excretion by kidneys is caused by
What attracts water to exert colloid osmotic pressure
decreased colloid will cause water to do what
leave intravascular compartment (plasma) and go into intersitial spaces. resulting in edema
what contributes to fluid volume deficit with in intravascular compartments
To maintain water balance, output shoud be within how many cc's of intake?
packed red cell volume exxpressed as a percentage of the total blood volume
normal hema for men and woman
40-54 men
38-47 wom
raise im hema is from
dehydration or water loss
hema decreases with
hemodilution aka... fluids excessively retained.
test that measuresamount of byproduct of muscle metabolism that is excreted by kidneys.
serum creatinne
normal serum creatine is
serum creatinine increases with what disease? and decreases with what?
kidney disease
muscle atrophy
test of amount of nitrogenous product present in blood as urea
normal BUN test is
Increase in BUn with? and decreased with
kidney dysfunction and decreaed with malnutrition, water excess, hepatic damage
Urines degree of concentration is?
urine specific gravity
evaluates kidneys abliity to cnserve or excrete water
urines specific gravity
normal urine specific gravity level is
affected only by the number of particles 50-1400 mOsm.
