Cell Function, Acid/Base Effects Flashcards
NRG of motion
Kinetic energy
erratic rando movement of microscopic particles in fluid, result of continuous assault from molecules of surrounding medium
Brownian motion
movement of particles from high conc. to low conc.
Diffusion
?
Concertation gradient
?
Equilibrium
?
Selectively permeable membrane
movement of water across a selectively permeable membrane from solutions of HIGHER water conc. to LOWER water conc.
Osmosis
potential of water to travel down its conc. gradient
Osmotic potential
?
Hypertonic
?
Hypotonic
?
Isotonic
?
Osmotic pressure
?
Crenation
?
Hemolysis
occur when pressure of a fluid forces particles thru a filtering membrane
Filtration
?
Selectivity
result when pressure of a fluid forces particles thru a filtering membrane; occur in Kidneys
Filtration rate
Higher [H+] = lower pH
Acid
Lower [H+] = higher pH
Base
influenced by [H+], higher [H+] = LOWER pH (Acidic), lower [H+] = HIGHER pH (Basic)
pH
a soLn that can resist pH change upon addition of an acidic or basic components (Chemical Buffer sys., Respiratory Mechanisms, Renal Mechanisms)
Buffer
Stimulates brain & Arterial receptors > Respiration rate(UP) > Blood CO2(DOWN) > Blood H2CO3(DOWN) > pH(UP)
Result from Hyperventilation, causes nausea, numb, muscle fatigue, hand tremor (pH HIGHER then 7.45)
Respiratory Alkalosis
Stimulates brain & Arterial receptors > Respiration rate(DOWN) > Blood CO2(UP) > Blood H2CO3(UP) > pH(DOWN)
result from Hypoventilation, causes fatigue, drowsiness, headache (pH LOWER than 7.35)
Respiratory Acidosis
Hyperventilation
CO2 is eliminated faster than its produced
Hypoventilation
CO2 builds up
