Welcome to the world of (C)1999 The World of Blood.

Introduction Everyone should have known something about the blood. For instance, blood is red, blood is a fluid, blood moves in blood vessels, blood oozes out when our skin is cut, blood is pumped by the heart, etc. These ideas are certainly true, but blood is not that simple. Being the only tissue that flows throughout the body, from head to toes, from internal to peripheral organs, blood has an indispensable role in maintaining our lives.   Blood is the fluid of health, the fluid of protection, the fluid of life. Each drop of the 5.6 litres of blood in our body is meant to support our life. So never underestimate the significance of the miraculous blood!
