What percentage of the total volume of blood does plasma comprise?

• A. 20-30 percent
• B. 30-40 percent
• C. 50-60 percent
• D. 70-80 percent

Answer: (C)

Plasma comprises approximately 50-60 percent of the total volume of blood. This liquid component of blood is essential as it serves multiple critical functions, including transporting nutrients, hormones, and proteins to the cells, as well as playing a significant role in maintaining blood pressure and regulating body temperature. Plasma is predominantly composed of water (about 90-92%), along with various solutes like electrolytes, nutrients, waste products, gases, and proteins such as albumin, globulins, and fibrinogen. The other ranges provided do not accurately reflect the physiological composition of blood. A percentage of 20-30 percent would imply an insufficient amount of plasma to perform its essential functions. Similarly, 30-40 percent and 70-80 percent do not represent the typical physiological state. Generally, understanding the composition of blood components is crucial for various applications in animal health, including diagnostics and treatment protocols.
