What is the primary component of plasma?

The primary component of plasma is water. Plasma is the liquid part of blood that helps transport nutrients, hormones, and waste products throughout the body. It consists of about 90-92% water, which plays a crucial role in maintaining blood volume and pressure, as well as regulating body temperature. Since plasma is largely made up of water, it serves as a solvent for various substances essential for bodily functions. The remaining components of plasma include proteins, electrolytes, gases, and nutrients, all of which are dissolved in the watery matrix, but water remains the predominant substance.
