What are the three important plasma proteins?

Albumins, Globulins, and Fibrinogen
Albumins, Collagens, and Lipids
Globulins, Immunoglobulins, and Cholesterols
Fibrinogen, Hemoglobin, and Myoglobin

The correct answer is: Albumins, Globulins, and Fibrinogen

The three important plasma proteins are albumins, globulins, and fibrinogen. Albumins are the most abundant plasma proteins and play a critical role in maintaining the osmotic pressure of blood, which is essential for proper fluid balance between blood and tissues. They also serve as carriers for various substances, including hormones, vitamins, and drugs. Globulins are a diverse group of proteins that include antibodies (immunoglobulins), which are vital for the immune response. They also serve various transport functions and contribute to the blood's viscosity and immune functioning. Fibrinogen is essential for blood clotting. Upon injury to blood vessels, fibrinogen is converted into fibrin, which forms a mesh that helps to stabilize blood clots, thereby playing a crucial role in hemostasis. Collectively, these proteins serve significant physiological functions, including maintaining blood volume, transporting substances, and facilitating blood clotting, making them fundamental to overall health and homeostasis.
