Lesson 33: Gaseous exchange at the lungs

Hi,

These cheerful Powerpoint slides are more suitable for the Pure Biology students. It deals with details of how oxygen and carbon dioxide travel in the blood.

The details of how carbon dioxide enters the red blood cell and form carbonic acid which later dissociates to form hydrogen ions and bicarbonate ions. The bicarbonate ion then diffuses back into the plasma and travels to the lungs and then enter back into the rbc. This reaction occurs in the reverse order to form carbon dioxide which then diffuses into the alveoli. This concept is well explained with large diagrams.
