What is the function of tryptase
an enzyme that can break up proteins , in other words protease
what is anaphalaxsis
a sever whole body allergic reaction to triggers
which amount of tryptase in the blood serum may indicate anaphylaxisis
11.3 ng/ml
what kind of cells have tryptase
mast cells
where are mast cells found
in the airways , dermis and intestines
what is the function of a logarithmic scale
it allows us to get very different things on the same graph
what kind of particles are used to transport lipids through the blood stream
lipoproteins
how many red blood cells are there usually in 1 ml of blood
between 4.6- 6 *10^9
in a milliliter of blood how many white blood cells are there usually
5.0 -10*10^6
what are the function of neutrophils
in the first line of defense against invading substances
what are the function of monocyte
when activated ,becomes macrophage which eats bacteria cellular debreis
what is the avg diameter of of red blood cells
betwen 6 and 8 microns
what does the velocity of settling depend on
radius squared
did einstein help us figure out how fast particle settle
yes
does a bigger particle fall faster or slower
faster
during inflammation what can happen to red blood cells
they can stick together and form rouleaux
does rouleaux or single red blood cells fall faster
rouleaux
what are extra large red blood cells called
macrocytes
what did einstein talk about in his dissertation
he analyzed the motions of molecules
what does ESR mean
it is the erythrocyte sedimentation rate
what is the normal ESR for red blood cells
25 mm/hour
what is a higher ESR rate associtated with
with infections, inflammation (such as rheumatoid arthritis), certain cancers
(such as multiple myeloma) or other factors
can a fast ESR rate make a clear determination of inflammation
ESR is only considered a “marker” for inflammation since other information (symptoms,
tests) is needed for a more precise diagnosis.
WHY does inflammaiton lead to a higher ESR ?
Inflammation lead to higher ESR because where there is more inflammation, there is likely
to be more fibrinogen, which may promote the formation of rouleaux.
What are the 3 types of waves
light , sounds, mathematical
what is the speed of sound waves in air at 20 degrees
342 meters / sec
what is the speed of light or energy waves
300 million meters/ sec
how do you calculate the speed of a wave
frequency times wavelength
what are the units of frequency
hertz
do all waves travel at the same speed regardless of material
no , it depends on the material
what is the speed of sound in air
340 m/sec
what is the speed of sound in water
1500 m/sec
does the speed of sound increase or decrease or with increasing temperature
speed of sound in air increases as temperature increases
how are electromagnetic waves different than waves of water
The difference is that EM waves consist of oscillating electric fields (not to mention magnetic fields).
This means that they can make electric charges, like electrons, move up and down.
can electromagnetic waves make electric charges
yeah
what is the function of the capillary
carries blood to muscle cells
how big is the average human blood cell
7.8 micro meters
what is endothelium
the single layer of cells that lines the inside of arteries veins and capillaries
diapedesis
burrowning between cell that leukocytes do
what does macrophage mean in greek
the big eater
what do macrophages do
eat bacteria worn out erythrocytes and LDL
what is athrosclerosis
hardening of arteries
what do macrophages usually start out as
monocytes
what do macrophages become when they take up lipids
foam cells
what is apatitie
it is a crystal that is high in phosphourus with a tiny bit of uranium . Fission tracks form in it
