Verified step by step guidance

Understand that plasma proteins are crucial components of blood plasma, playing roles in maintaining osmotic pressure, transporting substances, and participating in immune responses.
Identify the main types of plasma proteins: albumin, globulins, fibrinogen, and prothrombin.
Recognize that albumin is the most abundant plasma protein, constituting about 60% of the total plasma protein content.
Albumin is primarily responsible for maintaining the osmotic pressure of blood, which is essential for proper distribution of body fluids between blood vessels and body tissues.
Consider the functions of other plasma proteins: globulins are involved in immune functions, fibrinogen is crucial for blood clotting, and prothrombin is a precursor to thrombin, also involved in clotting.
