quiz 2 Flashcards
absorption
colloidal dispersion absorb molecules
active transport
mechanism that moves
material across the cell membrane
actual pressure
the resultant pressure reading when the rate of flow valve is opened
delivery of arterial solution
from the embalming machine through the tubing
and arterial tube into the artery; also referred to as injection
differential pressure
difference between actual pressure and potential pressure is the rate of flow
diffusion of arterial solution
from within the vascular system through the
capillary walls and into the tissue spaces
distribution of arterial solution
from the point of injection throughout the
arterial system and into the capillaries
extravascular resistance
resistances outside the blood vessels
fluid distribution (diffusion?)
improving arterial solution distribution
- increase rate of flow
- increase pressure
- inject arterial solution using pulsation
- restrict drainage
- massage along pathway of artery
- inject adequate amount of solution
- relieve abdominal extravascular pressure
injection pressure
amount of pressure produced by an injection device
to overcome initial resistance within the vascular system
intravascular pressure (IVP)
- causes pressure filtration which is the most important passive physical transport systems
- moves embalming solution from the capillaries to the tissue fluids
intravascular resistance
resistances within the blood vessels
observations prior to injection
presence or absence of livor mortis, degree of rigor mortis, distension of veins/small arteries, skin discolorations, and tissue firmness
osmosis
the passive transport mechanism involved with liquid (or
solvent) movement
(through a semipermeable membrane)
