|
|
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
