Question

Quizplus · Accepted Answer

Plasma oncotic pressure is primarily caused by the presence of plasma proteins, especially albumin.

Blood pressure, lymph, and electrolytes such as sodium and chloride can also play a role in fluid balance, but they are not the primary cause of plasma oncotic pressure.
