Blood is life

Description

Every second 2.5 million red blood corpuscles are formed in our bodies; in their 120-day life expectancy each will cover about 250 miles in our blood vessels. In the course of a human's life, 200,000 tons of blood are pumped through the body, supplying each individual cell with its necessities, removing waste products, and playing a critical defensive role in warding off foreign cells. That we can survive tropical heat and arctic cold with a relatively constant working temperature is only possible because of our blood. This program provides a thorough introduction to our blood.
