The urinary system does all of the following, except that it:

a. eliminates organic waste products.

b. excretes excess albumen molecules.

c. regulates blood volume.

d. contributes to stabilizing blood pH.

e. regulates plasma concentrations of electrolytes.

b. excretes excess albumen molecules

Explanation:

Albumin is a type of globular protein which is present in the blood plasma and it is about 75-78% of the plasma. It is a small protein soluble in water. Its main role is to maintain the oncotic pressure of blood by binding to water fatty acids, cations and hormones. When albumin level falls and no longer sustain sufficient colloid osmotic pressure, then to counterbalance hydrostatic pressure, swelling of body (edema) develops. The urinaray does not excretes excess albumen molecules from the blood.
