    The colloid osmotic pressure of blood is due to

    A)                  albumin                              

    B)  globulin

    C)                  fibrinogen                         

    D)  All of these

    Correct Answer: D

    Solution :

                     Proteins are present in plasma. Mostly the proteins present in plasma are of 3 types : Serum albumin constitutes about 50% of the total protein and produces 75-80% of colloidal osmotic pressure. The protein binds plasma calcium and some fatty acids. Globulins are 16% of total plasma protein and are of 3 types-\[\alpha \], \[\beta \]and \[\gamma \]-globulin. \[\alpha \]-globulin is involved in transporting thyroxine and bilirubin. \[\beta \]-globulin binds vitamin-A, D and K, cholesterol and ions. \[\gamma \]-globulins are immunoglobulins. Fibrinogen forms fibrin during blood clotting. Blood protein also helps to retain water in blood and functions as pH buffer.
