👉 The ne-fluid, often referred to as blood, is a complex biological fluid that plays a crucial role in maintaining life. It is primarily composed of water, red blood cells, white blood cells, platelets, and various proteins, electrolytes, and gases like oxygen and carbon dioxide. Red blood cells carry oxygen from the lungs to tissues throughout the body, while white blood cells are part of the immune system, defending against infections. Platelets help in blood clotting to prevent excessive bleeding. The fluid's composition and function are essential for nutrient transport, waste removal, temperature regulation, and overall homeostasis in the human body.
