What is the main function of plasma in the blood?

• A. Wafts oxygen to body cells
• B. Transports nutrients
• C. Takes carbon dioxide away from body cells
• D. Stores fat for energy

Answer: (C)

The main function of plasma in the blood is to transport nutrients, which makes the selection of that answer the most appropriate choice. Plasma constitutes about 55% of blood volume and is primarily composed of water, electrolytes, proteins, hormones, and waste products. It serves as a medium for various substances to travel through the circulatory system, ensuring that essential nutrients, such as glucose, amino acids, and vitamins, are delivered to body cells. In addition to nutrient transport, plasma also plays a critical role in maintaining blood pressure and volume, regulating body temperature, and facilitating the removal of waste products like urea and carbon dioxide, which are taken from body cells to the organs responsible for excretion. While some options relate to functions of other components of blood, it is plasma's role in nutrient transport that stands out as its primary function.
