|
Definition
| lobed nuclei with granules |
|
|
Term
|
Definition
| 2-6 lobes. chemotactically drawn to infection. anaerobic via glycogen supply. phagocytize dead cells. major component of pus. |

|
Term
|
Definition
| extension from lobes in some neutrophils from females contains inactivated X chromosome. |
|
|
Term
|
Definition
| bi-lobed. red granules. most common in intestinal and respiratory mucosa. indicate parasites or allergic. phagocytize Ag/Ab complexes. |
|
|
Term
|
Definition
| purple granules. precursor to mast cells. release histamine and other vasoactive mediators during immediate hypersensitivity or anaphylactic response. |
|
|
Term
|
Definition
| biconvex disc. 2-4micrometers. formed from megakaryocytes. 3 types of granules. cytoskeletal filaments. component of intrinsic clotting mechanism. release serotonin which is a vasoconstrictor. |
|
|
Term
|
Definition
| all blood cells derived from a common cell called a hemocytoblast |
|
|
Term
|
Definition
| one stem cell for granulocytes and another stem cell for all other blood cells |
|
|
Term
|
Definition
| occurs in bone marrow. cell size decreases. nucleus eccentrically located prior to expusion. cytoplasm becomes increasingly larger constituent of cell and changes from highly basophilic due to ribosomes to eosinophilic due to Hb |
|
|
Term
|
Definition
| made by kidney. increase in response to hypozia. controls hematopoiesis |

Term
| macP of spleen, liver, BM |
|
Definition
| remove Hb retaining fragments and senile RBCs from circulation. break down to billirubin and iron. iron recycled as feritin or hemosiderin. bilirubin sent to liver to be excreted with bile |
|
|
Term
|
Definition
| precursor cells represent 60% of BM cells. spend less time in blood (6-10 hrs). short functional lifespan (10 days in connective tissue). |
|
|
Term
| order of granulocytopoesis |
|
Definition
myloblast>>specific promylocyte>>mylocyte>>metamylocyte>>band(stab) cell>>granulocyte
cell size decreases, nucleus becomes smaller and eventually forms lobes. granules appear at mylocyte stage. |
