What percentage of plasma is composed of water?

Plasma, the liquid component of blood, is crucial for various bodily functions, and approximately 92% of plasma is composed of water. This high water content is essential because it serves as a solvent for carrying various substances, including nutrients, hormones, and waste products throughout the body.
