for serum:
draw blood with a red or tt tube. Draw enough blood( 2.5 x how much serum you need) then let it sit for 30-45 min to clot. Then centrifuge it for 10-15 min. the serum(plasma with no fibrogin, glucose, sodium, antibodies, hormones) will be on top layer, clotted blood will be on bottom layer
for plasma
draw blood from lavender, green, grey, light blue tube. Invert each tube 8-10 after draw. Then centrifuge it for 10-15 min. Get 3 layers, plasma (proteins, globulans, electrolights fibrogin), buffy coat (WBC and platelets), packed RBC.
plasma
straw colored portion of blood
transports substances
92% water
carries plasma proteins, globulins, electrolytes, fibrinogen
serum
plasma that contains no fibrinogin
contains dissolved substances, glucose, sodium, antibodies, hormones
WBC
fight infection
types of WBC
NEVER LET MONKEYS EAT BANANAS
neutrophils, lymphitocytes, monocytes, eosoniphils, basophils
neutrophils
most numerous, increase with acute infection, immature cells are called bands.
lymophitocytes
smallest WBC, involved with immune system, increase with viral infection, making antibodies
monocytes
largest WBC
eosoniphils
increase with allergic conditions(allergies)and parasitic infection
basophils
least numerous of WBC
RBC
formed in bone marrow of flat bones and ends of long bones. (ribs, sternum, skull, pelvic bones, end of arms and leg bones)
no nucleus in mature cell
does RBC have a nucleus
for greater surface area to pick up oxygen
why is RBC shaped like a disc with middle concaved (bi concave)
oxyhemoglobin
oxygen combined with hemoglobin
120 days and no
how long do RBC live and do they replicate
hemoglobin (heme protein makes it red)
where does blood get it's red color
leukocytosis
too many WBC
hematocrit
what measures the % of packed blood cells
differential WBC
the blood smear that looks at all the WBC
platelets
another name for thrombocytes
