Life Without These Body Fluids Is Impossible

 Blood
Perhaps the most important body fluid of all is blood. The average adult contains about six liters of blood, which functions to transport oxygen to cells, carry metabolic waste products such as carbon dioxide away from cells and transport infection-fighting white blood cells, glucose, hormones and other essential substances throughout the body. Blood also contains cell fragments called platelets and clotting factors that help to seal leaks that may develop in blood vessels.An adult’s body contains about 25 trillion red blood cells – about one-third of all the body’s cells. Red blood cells survive on average about 120 days, which means that every second of every day, an adult human produces about two million red blood cells. If lined up end to end, the tiny blood vessels in which gas is actually exchanged, the capillaries, would reach a length of about 60,000 miles, long enough to encircle the earth more than twice.
