3 main sites of hematopoesis during conception and early fetal months
yolk sac, liver, spleen
Adult Bones Hematopoesis, acrynom
SSPRVSkull, SternumPelvis, Ribs, Vertebrae
Heme needs these two things
iron and protoporhyrin
Protein that transports Fe
transferrin
Major storage form of iron
Ferritin
Long term storage of insoluble Fe
Hemosiderin
Enzyme def w/build up of heme precursors is called
porhyrias
While in the DELTA, POR UR COP PRONTO a cup of HEME
Heme Precursors

In Hmg oxy diss curve, oxygen is released or not released in a shift to the left
not releasedNo, won’t let go
In Hmg oxy diss curve, oxygen is released or not released in a shift to the right
releasedwon’t hold tight
To determine Hmg, the oxidation of hmg to methmg is done with these two reagents
KCN and KFerricyanide
