Chemistry: Challenges and Solutions

The Buffer System in the Blood (animation)

A huge amount of carbon dioxide is produced in our bodies and has to be moved to the lungs to be expelled. It combines with water to make carbonic acid, which partially dissociates into hydronium and bicarbonate. Then, when the blood reaches the lungs, the carbon dioxide comes out of solution and is expelled. Finally, the buffered blood circulates through the body, repeating the task.
