👉 A functioning fluid, often referred to as blood in the human body, is a complex mixture of cells and proteins that circulates throughout the circulatory system. It primarily consists of red blood cells, white blood cells, platelets, plasma, and various other substances like proteins and clotting factors. Red blood cells transport oxygen from the lungs to tissues and return carbon dioxide back to the lungs for exhalation. White blood cells are part of the immune system, defending the body against infections and foreign invaders. Platelets help in blood clotting to prevent excessive bleeding when vessels are injured. Plasma, the liquid component, carries nutrients, hormones, and waste products while also facilitating the transport of red blood cells and white blood cells. This dynamic fluid system ensures the efficient exchange of materials, maintains homeostasis, and supports overall bodily functions.
