What is the primary component of blood plasma?

The primary component of blood plasma is water, making up about 90-92% of its composition. Water serves several crucial functions in the body, including acting as a solvent for various substances, facilitating the transport of nutrients and waste products, and helping maintain blood volume and pressure. The high water content is essential for sustaining the fluidity of the blood, allowing red blood cells, white blood cells, and platelets to flow easily throughout the circulatory system. While proteins, hormones, and other components are important and present in plasma, they constitute a much smaller percentage of its total volume compared to water.
