water function

90% of plasma volume; solvent for carrying other substances; absorbs heat

salts (electrolytes) function

osmotic balance, pH buffering, regulation of membrane permeability

plasma proteins function

osmotic, balance, pH buffering, blood clotting , antibodies and lipid tranport

erythrocytes- transport O2 bound to hemoglobin molecules; also transport small amount of CO2

neutrophils- active phagocytes; number increases rapidly during short-term infections

eosinophils- kill parasitic worms with digestive enzymes

basophils- release histamine at sites of inflammation

lymphocytes- B lymphocytes produce antibodies; T lymphosytes graft rejection, fighting tumors and viruses, via direct cell attack

monocytes- active phagocytes that become macrophages in tissue

platelets- normal blood clotting; initiate clotting by clinging to torn area

type A- aggulinates with anti A

Type B- aggulinates with anti B

type O- contains no antigens, no aggulination

buffy coat composition
