👉 The fluid, often referred to as blood in the context of biological systems, plays a crucial role in maintaining life and homeostasis within an organism. It is a complex mixture of cells, primarily red blood cells, white blood cells, platelets, and plasma. Red blood cells transport oxygen from the lungs to tissues and carry carbon dioxide back to the lungs for exhalation. White blood cells are part of the immune system, defending against infections and foreign invaders. Platelets aid in blood clotting to prevent excessive bleeding from injuries. Plasma, the liquid component, carries nutrients, hormones, and waste products throughout the body. Together, these elements ensure efficient transport, defense, and repair processes, making the fluid integral to bodily functions.
