Fibrinogen ( plasma protein) Role in clotting only when necessary
Difference between plasma and serum Plasma has clotting factors . Liquid minus formed
elements and contains fibrinogen.
Serum is like plasma does not contain fibrinogen but has all electrolytes, antibodies, antigens,
hormines.
What is found in red bone marrow Erythrocytes

Acts as buffers
Lifespan 105 to 120 days
Contains carbonic anhydase
What is carbonic anhydase Enzyne that combines with co2 form the waste and forms
carbonic acid which dissolves easily in blood.
Function of rbc in 02 and co2 transport A. Carries o2 to cell for cellular respiration
B. Carries waste carbon dioxide ( most hydrated to bicarbonate which is released into blood back
to lungs.)
cc. In the lungs it is reformed (rehydrated in rbc) into co2 and exhaled
