IC1 Flashcards
what is present inside the plasma
albumin, fibrinogen, immunoglobulins, lipids, hormones, vitamins, salts.
what is serum
protein rich fluid lacking fibrinogen but containing albumin, immunoglobulins, and other components
what is the pH of blood
7.35-7.45 (slightly alkaline)
function of albumins
contribute to osmotic pressure
transport of lipids, steroid hormones
percentage of albumins in protein component of plasma

function of globulins
transport of ions, hormones, lipids
immune function

35%
percentage of fibrinogen in protein component of plasma
4%
function of fibrinogen
essential component of clotting system

water = 92
proteins = 7
other solutes = 1
what are the major electrolytes and what are their purpose
