green tube

heprin
blood gases, ph studies
whole blood

lavender tube

epta
hamatology studies, cbc, hgb, Hct

whole blood

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
