RESPIRATORY SYSTEM
MAIN PURPOSE: Replace oxygen and remove carbon dioxide from the blood. This gas exchange occurs in the lungs within microscopic air sacs called alveoli.
WE ALL HAVE MAJOR AIR TRAFFIC CONTROL:
1. Air enters either your nose or mouth.
2. The air is warmed and travels through the pharynx.
3. Down the larynx ("Adam's apple)
4. Through the trachea (windpipe)
5. To the right and left primary bronchi
6. To the secondary bronchi, one for each lobe of the lung
7. To the tertiary bronchi
8. Into tiny bronchioles
9. Air continues to branch into terminal bronchioles and then even smaller respiratory bronchioles
10. Travel ends in clusters of alveoli (thin-walled air sacs)

| The lungs contain approximately 300 million alveoli, which provide an enormous surface area for gas exchange. It is estimated that the total surface area available for diffusion in the human lungs is about the size of a tennis court! |
HOW CAN YOU KEEP YOUR LUNGS HEALTHY?
Exercise regularly! By working your respiratory muscles you will increase your oxidative capacity and improve your respiratory endurance. The more your lungs get used to working out the more they will adapt and strengthen, making working out easier and you will experience less shortness of breath! So, get off the couch and get moving to work those lungs!
The blog looks awesome! So glad you were able to size the picture down. The birds in the right margin at the top really work with the picture as well....they look like an extension of the pic!
ReplyDeleteMy only suggestion would be to alter "it's the only place you have to live" so that "to live" is more readable. Perhaps make it two lines?
