Summary Introduction
Introduction:
Blood is a liquid, which runs throughout the body of the human beings. It comprises blood cells and platelets. Another vital element that it transports is hemoglobin, which is basically an iron consisting of a metalloprotein. This binds with the oxygen and then moves throughout the body.
