👉 Acute fluid, also known as plasma, is the liquid component of blood that makes up about 55% of its total volume. It's primarily composed of water, but also contains proteins, electrolytes, nutrients, hormones, and waste products. Unlike the clear, straw-colored fluid found in other parts of the body, acute fluid is opaque and contains various cellular components such as red blood cells, white blood cells, platelets, and plasma proteins. This fluid plays a crucial role in transporting nutrients, oxygen, hormones, and waste throughout the body, maintaining blood pressure, and supporting immune function.
