Blood Plasma •Roughly 92% water, mixed with organic and inorganic substances •The most abundant plasma solute is the plasma protein , of which there are three groups : albumins , globulins , and fibrinogen Albumins : ~60% of the plasma proteins are albumins; they are the smallest of the proteins. They help to maintain osmotic pressure in the blood. Globulins : ~36% of the plasma proteins. Alpha and beta globulins are, like albumins, made in the liver. They transport lipids and fat-soluble vitamins, among other things. Gamma-globulins are made in the lymphatic system, and they include antibodies. Fibrinogen : ~4% of the plasma proteins; works in the blood clotting mechanism. It is the largest of the plasma proteins and is made in the liver. •A decrease in the number of plasma proteins can lead to a change in the osmotic pressure, resulting in edema. • Plasma also contains plasma nutrients (such as amino acids, simple sugars and lipids) and the blood gases (O 2 and CO 2 ) •Non-protein nitrogenous substances are also found in the plasma. Urea , uric acid and amino acids fall into this category. The kidneys keep the levels of these substances low by constantly removing them. •Plasma electrolytes include Na + , K + , Ca 2+ , Mg + , Cl - , HCO 3 - , PO 4 - , SO 4 . They work in maintaining osmotic pressure and blood pH, among being essential for many metabolic processes.
