..well..ok..too blobby to be a tiger..but they
ferocious eaters like tigers.
..I was doing a quick check on blood drops
looking for the "particles that sprout bad things".
..see if the numbers of particles are going up or down.
only two drops examined...no particles
then got distracted by this
big blobby critter.
No movement observed. Critter was likely
disabled/dead by the time I found him;
the tungsten lamp on the scope is really
too HOT for viewing critters...they die quickly.
His size, at 30 microns is right in the zone for macrophages. Rather surprised to find a macro in a
capillary blood sample. I was under the impression that
once a monocyte moved into tissue to grOW into a macrophage
that they stayed in the tissue. Maybe this one didn't
get the memo. Or maybe the "authoritive source" is over simplifying things. Perhaps the tale is more like that they PREFER to hang in tissue..but can be dragged back
into "the river" on occasion. Suspect that big "blood tigers" find the smalles capillaries a very tight fit.
The smallest capillaries force blood cells to go thru in single file..[red blood celldiameter appx 7 microns..30 micron wide macrophage would have a hard time of it]
I did note the other large critter..about half the size
of the macrophage..I strongly suspect it to be a monocyte.
[also a fierce hunter...just a smaller one..a baby tiger
actually..since the mono's can grow up to be a macrophage]
...I really do need to upgrade the "hunting tools"..and
be able to see these hunters in action..alive..
a microscopic version of Wild Kingdom...only thing missing
would be Marlon Perkins, Jim Fowler and the Land Rover.
