D2 - Basic Blood & Cells of Immune system Flashcards
thrombocytes
platelets
assist in clotting
erythrocytes
red blood cells
have extruded their nuclei, gotten a bi-concave disk shape (to maximize surface to volume ratio)
produced in bone marrow
leukocytes
white blood cells
includes:
granulocytes
monocytes
lymphocytes
hematocrit
volume of packed red blood cells
4 main components of plasma
water
salts (ions)
plasma proteins (fibrinogen, immunoglobulins)
substances being transported by the blood (nutrients, waste products, respiratory gases, hormones)
4 substances that might be in plasma, getting transported by the blood
nutrients
waste products
respiratory gases
hormones
plasma vs. serum
serum = liquid portion of plasma AFTER coagulation (took out the fibrinogen)
neutrophil
think “nucleus” - has many segments in nucleus
think “many nucleus” –>many types of bacteria–>good for engulfing bacteria
eosinophil
think “eel” - which is like a worm. deals with parasites/worms
think “eeew parasites,” cell looks “infested” w/ red dots
basophil
“basic phil is so basic. nothing but purple”
“basic phil is allergic to everything” - contains heaparin, histamine, other factors of inflammaiton
promote anaphylactic rxns
monocytes
“MONocytes is a real MON/MAN” - really big
“stupid man has kidney shape brain” - has kidney bean shaped nucleus
antigen presenting cell
lymphocytes
spherical nucleus
sky blue cytoplasm
virus; tumor cells
T cells, B cells, NK cells
relative abundance of nucleated cells in peripheral blood (monkeys)
Never Let Monkeys Eat Bananas
N>L>M>E>B
hemopoiesis/hematopoiesis
“blood making”
always occurs in the bone marrow
sinusoid
a permeable capillary
in bone marrow, allow blood cells formed in bone marrow into the capillary
in a histo stain, can ID sinusoid b/c they have lots of mature RBCs in them
