Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
what function do majority of plasma proteins serve?
A
regulate osmotic pressures in the blood
B
participate in the immune system
C
involved in the clotting process
D
neutralize digestive trypsin
Explanation: 

Detailed explanation-1: -Plasma proteins, such as albumin and globulin, that help maintain the colloidal osmotic pressure at about 25 mmHg. Electrolytes like sodium, potassium, bicarbonate, chloride, and calcium help maintain blood pH. Immunoglobulins help fight infection and various other small amounts of enzymes, hormones, and vitamins.

Detailed explanation-2: -Ions and glucose contribute to 95% of the osmotic pressure as they are the most abundant in the serum.

Detailed explanation-3: -By far, the protein with the greatest contribution to the colloid osmotic pressure in the plasma/capillary space is albumin (21.8 mm Hg), followed by globulins (6 mm Hg), and then fibrinogen (0.2 mm Hg), giving a total colloid pressure of 28 mm Hg to move fluids inward.

Detailed explanation-4: -Albumins, group of proteins produced by the liver, are present in human plasma and serve to maintain the osmotic concentration of blood and thereby maintaining blood volume and blood pressure.

Detailed explanation-5: -Albumins regulate the osmotic pressure of the blood (and hence moderate the osmotic pressure of body fluids) Globulins participate in the immune system (i.e. immunoglobulins) and also act as transport proteins. Fibrinogens are involved in the clotting process (soluble fibrinogen can form an insoluble fibrin clot)
