👉 The familiar fluid you're referring to is likely blood, a vital bodily substance that circulates throughout the body. Blood is a complex mixture of cells, primarily red blood cells, white blood cells, and platelets, suspended in plasma—a clear, colorless liquid. Red blood cells carry oxygen from the lungs to tissues and return carbon dioxide for exhalation, while white blood cells are part of the immune system, defending against infections. Platelets aid in blood clotting to prevent excessive bleeding. Together, these components make up the fluid that ensures essential nutrients and oxygen are delivered to cells while waste products are removed.
