net filtration - answers✔✔forces favoring filtration minus forces opposing filtration
Osmolarity - answers✔✔concentration of osmotically active particles in a solution
isosmotic - answers✔✔solutions with the same concentrations of solute particles (osmolarity)
hyposomotic - answers✔✔solution with lower osmotic pressure. lower outside
hyperosmotic - answers✔✔solution with higher osmolarity. higher inside.
isotonic - answers✔✔two solutions with the same osmotic pressure
Hypotonic - answers✔✔when comparing two solutions, the solution with the lesser
concentration of solutes within the cell
Hypertonic - answers✔✔when comparing two solutions, the solution with the greater
concentration of solutes within the cell
Forces favoring filtration - answers✔✔Capillary hydrostatic pressure (blood pressure) and
interstitial oncotic pressure (water-pulling)
Forces favoring reabsorption - answers✔✔Plasma (capillary) oncotic pressure (water-pulling)
Interstitial hydrostatic pressure
edema - answers✔✔accumulation of fluid within the interstitial spaces
causes of edema - answers✔✔increased capillary hydrostatic pressure (increased BP),
decrease of plasma oncotic pressure,
obstruction of lymphatic circulation,
increased capillary permeability

What is ascites? - answers✔✔accumulation of fluid in the peritoneal cavity
example of increased capillary hydrostatic pressure - answers✔✔venous obstruction, salt and
water retention, heart failure, renal failure
what does increased capillary hydrostatic pressure cause? - answers✔✔forces fluid into
tissues
causes of decreased capillary (plasma) oncotic pressure - answers✔✔decreased plasma
albumin
-decreased synthesis of plasma proteins (cirrhosis, malnutrition)
-increased loss of plasma proteins (nephrotic syndrome)
increased Na+ and H2O retention (dilution of plasma proteins)
what does lymph obstruction cause? - answers✔✔fluid movement into the tissues
decreased transport of capillary filtered protein ( thus increasing tissue oncotic pressure)
what are examples of increased capillary permeability? - answers✔✔burns and inflammation
what does increased capillary permeability do? - answers✔✔proteins escape= loss of plasma
proteins to interstitial space (thus increasing tissue oncotic pressure and decreased capillary
oncotic pressure)
papilledema - answers✔✔swelling and inflammation of the optic nerve at the point of
entrance into the eye through the optic disk
What causes papilledema? - answers✔✔often caused by increase in intracranial pressure
what is the primary extracellular fluid cation (positive charged ion)? - answers✔✔Sodium
