👉 The fluid, or blood, is a complex mixture of cells and substances that circulates throughout the body. Primarily composed of water, it contains red blood cells carrying oxygen and carbon dioxide, white blood cells that fight infections, platelets essential for clotting, and various proteins, hormones, and nutrients. This fluid acts as a transport system, delivering oxygen and vital substances to tissues while removing waste products, playing a crucial role in maintaining homeostasis and overall bodily function.
