body fluids are divided into two categories name them.
Intracelluar (ICF) and Extracellular (ECF)
____ comprises all fluid in cell.
Which ICF or ECF has more volume and by how much?
ICF; twice as much
The ECF is divided into two parts name them.
Intravascular and interstitial.
Where is intervascular fluid found?
In blood compartment (vascular compartment)
Where are interstitial fluids found?
Lymph, synovial, biliary, hipatic, pancreatic, cerebrospinal fluid, sweat, urine, plural space, pericardial space, perietal space, interocular space.
Give the definition of osmosis.
Movement of water down a concentration gradiant across a semipermeable membrane from an area of higher concentration to an area of lower conctration.
Give the definition of hydrostatic pressure.
mechanical for of water pushing against cellular membrane.
Give the definition of net filtration.
movement of fluid back and forth across capilary wall; high to low concentration; interstitial to intercelluar to venous and back to heart. the lymph system is also low pressure and can pick it up as well.
Give the definition of Osmolality.
distribution and movement of water between body compartments.
Give the definition of osmolarity.
measurement taking into account water and displacement when molecules are added.
Give the definition of oncotic and colloid osmotic pressure.
plasma proteins do not diffuse across cell membrane the are too big, they carry a negative electric charge and effect the particles that can cross and cell tries to maintain neutrality.
Give the definition of tonicity
guides us in what IV fluids to give to patients; describes the change in concentration of electrolytes in relation to water.
What is an isotonic solution?
same concentration of electrolytes as ICF and ECF
What is a hypotonic solution?
has a lower concentration of electrolytes than ICF and ECF, more dilute than body fluids.This solution will pull water into cells causing swelling. It is given if a patient is dehydrated. water is an example.
What is a hypertonic solution?
has higher concentration of electrolytes than ICF and ECF. will pull fluid out of cells causing shrinkage. dialysis is an example of this.
what is edema?
swelling from fluid
what is total body water? (percentage and amount)
60 % and 42 Liters
________ is the most abundant ECF ion.
________ is the most abundant ICF ion.
when you draw blood from a patient would expect more Na or K to be present?
More Na than K
what causes Increases Capillary Permeabilty?
proteins escape from vascular bed causing edema loss of capillary oncotic pressure and a gain in interstitial fluid proteins associated with inflamation or immune response (burn patients and crush injuries, alergic inflammatory reaction or cellulitis)
what causes decreased capillary oncotic pressure?
decreased in plasma albumin concentration contributes decrease in plasma oncotic pressure and in oncotic attraction of fluid with in cappilary causing fluid to move into interstitial space. ( people who have loss in protiens, cirrohsis, malnurished , and elderly).
what does decreased capillary oncotic pressure cause?
kideny diseases, hemoreage, drainage (clear) from wound.
what causes increased capillary hydrostatic pressure?
caused by obstruction, blood clot in vein, salt and H20 retention (anti-inflammatory drugs) conjuctaive heart failure, renal disease.
tell how lymph obstruction is connected to edema.
if there is an obstruction in the lmphatic system it can cause edema. sometimes with cancer some lymphnodes are removed and can cause lymphedema, parasites, trauma, or radiation therapy can also cause edema!
