What is the definition of plasma in the context of blood?

Plasma is defined as the liquid component of blood that serves a vital role in carrying various substances throughout the body. It is primarily composed of water, but it also contains important elements such as electrolytes, nutrients, hormones, proteins, and waste products. One of its primary functions is to transport blood cells—such as red blood cells, white blood cells, and platelets—along with essential nutrients like glucose, amino acids, and vitamins. Additionally, plasma helps maintain blood pressure and regulate body temperature.

The liquid nature of plasma allows it to effectively facilitate the exchange of nutrients and waste between blood and tissues, making it crucial for overall bodily function. It is essential to distinguish plasma from other components of blood that serve different purposes, such as clotting factors found in plasma but not defining its entire role.
