The role of plasma proteins is:
Correct answer: B. All of these
- A. To serve as imunoglobulins
- B. All of these
- C. To act as a buffer
- D. To serve as reserve proteins
Explanation
Plasma proteins have several functions. Plasma proteins, such as albumin and globulin, that help maintain the colloidal osmotic pressure at about 25 mmHg, act as a buffer. Electrolytes like sodium, potassium, bicarbonate, chloride, and calcium help maintain blood pH. Immunoglobulins help fight infection. They also act as reserve proteins in the case of amino acid deficiency.
