PLASMA AND THE CELLULAR ELEMENTS OF BLOOD Plasma is Extracellular Martix Plasma Plasma Proteins. Albumin.  Plasma is identical to the interstitial fluid except for the presence of Plasma Proteins. Albumin makes up 60% of plasma proteins. Albumin, with globulins , and clotting protein fibrinogen , and the iron transporting protein transferrin  make up more than 90% of all plasma proteins. Liver makes most proteins Immunoglobulins are not made in the liver Protein makes the osmotic pressure in the blood higher than the interstitial fluid Functions: Albumin - osmotic pressure of plasma, carrier protein. Globulins - Clotting factors, enzymes, antibodies, carrier protein Fibrinogen - Fibrin threads essential for clotting Transferrin - Iron transport Cellular Elements Including RBCs, WBCs, and Platelets BLOOD CELL PRODUCTION All blood descend from a pluripotent hematopoietic stem cell. This cell is found primarily in the  bone merrow .  Become uncommitted stem cells
