👉 The won fluid, also known as blood plasma, is the liquid component of blood that makes up about 55% of its total volume. It plays a critical role in maintaining homeostasis, transporting nutrients, hormones, and waste products, and facilitating blood clotting. Composed mainly of water (about 90%), proteins, glucose, electrolytes, and various dissolved substances, won fluid acts as a medium for the transport of cells, nutrients, and waste throughout the body. It also helps regulate body temperature and pH levels, making it essential for overall physiological function and homeostasis.
