👉 The main fluid, also known as blood plasma, is the liquid component of blood that makes up about 55% of its total volume. It plays a crucial role in transporting nutrients, oxygen, hormones, and waste products throughout the body, while also maintaining blood pressure and temperature. Composed mainly of water (about 90%), plasma contains proteins, electrolytes, glucose, and various nutrients essential for cellular function. Additionally, it carries waste products and toxins to be eliminated by the kidneys and liver, making it vital for overall bodily homeostasis and health.
