What is the primary function of plasma in the blood?

The primary function of plasma in the blood is to aid in the transportation of cells and nutrients. Plasma is the liquid component of blood, making up about 55% of its total volume. It carries red blood cells, white blood cells, and platelets throughout the circulatory system. Additionally, plasma serves as a medium for the transport of various substances, including hormones, nutrients from digested food, waste products, and proteins. This transportation is crucial for ensuring that all body tissues receive necessary substances for functioning and that waste products are carried away for excretion.

While plasma does play a role in other functions, such as maintaining blood pressure and regulating body temperature, its primary role remains focused on the transportation of cells and nutrients, which is vital for maintaining overall health and homeostasis in the body.
