Granulocytes
Large granulesInvolved in immunity

Hematopoiesis
Process of blood cell formation
Stem Cells
Live in bone marrow before becoming blood cells
RBC Transport
Most O2 transported by hemoglobin Most CO2 transported as bicarbonate ions (because of influence of carbonic anhydrase) and transported in plasma
Hemoglobin
4 heme groups4 globin molecules, each with 1 iron atom
Erythropoiesis
EPO (Erythropoietin) is the hormone that stimulates RBC production. Produced in kidneys. Homeostatically controlled by blood O2 levels.
WBC Movement
Ameboid: pseudopodia make 'em move like amoebaDiapedesis: cells become thin, elogate, and then move btwn or through endothelial cellsChemotaxis: attraction to and movement toward foreign materials
Hemostasis
Arrest of bleeding
Vascular Spasm
A type of hemostasisVasoconstriction of damaged bvs; leaks controlled by platelets
