👉 Adult fluid, also known as plasma, is the liquid component of blood that makes up about 55% of its total volume. It plays a crucial role in maintaining homeostasis, transporting nutrients, oxygen, hormones, and waste products throughout the body, and supporting immune function. Plasma contains water, proteins, electrolytes, glucose, lipids, and various dissolved substances, including hormones and drugs. This complex mixture ensures that cells receive essential nutrients and maintains the body's internal environment within a narrow, optimal range.
