Blood and Hemopoiesis Part II Flashcards
Large protein composed of four polypeptide chains, each is bound to heme group (iron-containing)
HEMOGLOBIN
_____ moiety is responsible for releasing CO2
Globin
R state and T state
HEMOGLOBIN
Hb carrying 2,3-DPG
Deoxyhemoglobin
Hb carrying O2
Oxyhemoglobin
Hb carrying CO2
Carbaminohemoglobin
Human polypeptide chain of Hemoglobin
α, β, γ, δ
Human polypeptide chain of Hemoglobin:
HbF (α2, γ2)
HbA1 (α2, β2)
HbA2 (α2, δ2)
In adult, ___ HbA1, ___ HbA2, ____ HbF
96%, 2%, 2%
Much smaller than that of RBCs in number
LEUKOCYTES
4,000-11,000/cumm
LEUKOCYTES
when leukocytes leave the bloodstream by migrating between endothelial cells of the blood vessels
Diapedesis
Both have azurophilic granules (lysosomes)
Granulocytes
Agranulocytes
GRANULOCYTES:
NEUTROPHIL
EOSINOPHIL
BASOPHIL
Formation of the granulocytes (NEB) under the influence of several cytokines, GCSF, GM-CSF, IL-1, IL-5, IL-6, TNF-alpha,
GRANULOCYTOPIESIS
Descendant of CFU-GEMM to CFU-Eo (Eosinophil) and CFU-Ba (basophil) forming myeloblast as precursor cell
GRANULOCYTOPIESIS
Neutrophil arise from CFU-GM to CFU-G forming myeloblast
GRANULOCYTOPIESIS
Also known as Polymorphonuclear leukocytes
NEUTROPHIL
The most abundant of all WBCs (60-70%)
NEUTROPHIL
Multilobed nucleus
NEUTROPHIL
In females, the nucleus presents a characteristic small appendages, the “drumstick” which contains the inactive x chromosome
NEUTROPHIL
One of the first cells to appear during acute bacterial infection
NEUTROPHIL
Phagocytose and destroy bacteria using the contents of their granules
NEUTROPHIL
contain various enzymes and pharmacological agents in performing antimicrobial function
Specific granules
