fluid inside the cell is called what?
|
intracellular fluid
|
|
3 types of extracellular fluid
|
1. intravscular fluid
2. interstitial fluid 3. organ fluid, spinal fluid, lymph nodes, ocular fluid |
|
fluid within blood vessels
|

|
|
fluid within tissues
|
interstitial fluid
|
|
movement of water through semi-permeable membrane; water moves from an area of lower solute concentration to an area of higher solute concentration (moves from more water to less water)
|
osmosis
|
|
movement of water from an area of high pressure to an area of low pressure
|
filtration
|
|
force/attraction for water caused by undissolved particles (protein and sodium); wherever protein and sodium go, water will follow
|
osmotic pressure/colloid oncotic pressure (pull of protein and sodium on water creates a pressure)
|
|
what assists in keeping fluid inside blood vessels?
|
osmotic pressure/colloid oncotic pressure
|
|
what is a pressure this is created from solutes?
|
osmotic pressure
|
|
what happens when there is too much sodium? can have weight gain, edema, distended neck veins, bounding pulse, high BP, difficulty breathing, crackles in lungs, and increased urine output
|
fluid volume overload
|
|
what happens when there is not enough fluid/insufficient hydration; excessive perspiration, fever, burns, hemorrhaging; can have weight loss, dizziness, confusion, dry lips, flat neck veins, slow cap, refill, decreased BP, decreased urine output, inelastic skin tugor
|
fluid volume deficit
|
|
fluid that is outside of the vein is what?
|
interstitial fluid
|
|
concentration of solute per volume of solution (mOsm/L)
|
osmolarity
|
|
what is the movement of particles?
|
diffusion
|
|
what is the movement of water?
|
osmosis
|
|
with active transport, _____ is needed
|
energy
|
|
what is the movement of water and particles?
|
filtration
|
|
when there is a high osmolarity of blood, the ______ signals that you are thirsty
|
hypothalamus
|
|
what stops you from urinating when there is a high osmolarity of the blood?
|
release of antidiuretic hormone
|
|
a patient with high osmolarity of the blood with have ______ BP
|
low
|
|
when a person is dehydrated, what hormone is relaesed?
|
ADH
|
|
if you have increased atrial natriuretic peptide (ANP), the body will....
|
excrete sodium
|
|
if you have decreased atrial natriuretic peptide, the body will...
|
retain sodium
|
|
so if the body has lots of water (low osmolarity), what will happen to atrial natriuretic peptide?
|
it will increase and sodium will be excreted
|
|
if the body has a high osmolarity (not much water), what will happen to atrial natriurectic peptide?
|
it will decrease and sodium will be retained in the body
|
|
what should blood pH be?
|
7.35 - 7.45
|
|
FYI...
|
an arterial sample of blood gives a more accurate blood pH
|
|
FYI...
|
the lower the number of pH, the more acidic
|
|

|
35 - 45 mmHg
|
|
is carbon dioxide an acid or base?
|
acid
|
|
is hydrogen an acid or base?
|
acid
|
|
is bicarbonate and acid or base?
|
base
|
|
what is the range for bicarbonate (HCO3)?
|
22 - 26 mEq/L
|
|
respiratory system controls only what?
|
CO2
|
|
Kidneys control what?
|
bicarb and hydrogen
|
|
if there is a respiratory problem, what compensates for that?
|
the kidneys
|
|
if there is a metabolic problem, what compensates for that?
|
respiratory system
|
