Approximately what percentage of plasma is made up of water?

• A. 70%
• B. 80%
• C. 90%
• D. 95%

Answer: (C)

Plasma, the liquid component of blood, consists predominantly of water, which serves as a medium for transporting various substances throughout the body, including nutrients, hormones, and waste products. The correct answer, which indicates that approximately 90% of plasma is made up of water, reflects the essential role of water in maintaining blood volume, regulating temperature, and facilitating many biochemical processes. The high percentage of water also contributes to the fluidity and viscosity of plasma, ensuring effective circulation within the bloodstream. This significant water content is fundamental for homeostasis and overall health.
