What percentage of blood is made up of plasma?

• A. 45%
• B. 55%
• C. 65%
• D. 75%

Answer: (B)

Plasma makes up approximately 55% of the total volume of blood in the human body. It is the liquid portion of blood that plays a critical role in transporting various substances, including nutrients, hormones, proteins, and waste products, throughout the body. Plasma also contains electrolytes, gases, and other components that are essential for maintaining homeostasis and supporting bodily functions. Understanding this composition is vital for grasping how blood functions in transportation and regulation within the circulatory system. Other percentages listed do not accurately reflect the typical composition of blood where plasma constitutes slightly more than half.
