I Can't Breathe... Until You're STUDYING Here With Me

Hi people!! How are you doing?What about the return to school after the long wekend??? It was not easy to BREATHE so early in the morning!! XD

Well, for you to remember that the verb is (to)breathE/d and the noun is BREATH , these are two of  my fav songs that contain these words: HERE WITH ME by DIDO (the tittle of this post is a line in this song)



and "Every step you take" in Glee's version







Have you been reading about  
RESPIRATORY SYSTEM???????






 I think you might like this video for  an accurate picture of the system. WOW!!!!!

As you  can see, the respiratory system is basically a long tube with two sacs at the end, with NO bones, only cartilages inside the tube (to prevent it from collapsing) and muscles outside the sacs to make them larger or smaller. This tube is covered by a thin EPITHELIUM that is full of CILLIA and secretes MUCUS  to prevent bacteria and other harmful substances to get to the ALVEOLI.

I'm also  including here some videos for you to revise your concepts:

1) An IGCSE video with a whole revision and a FIBROSCOPY of the RESPIRATORY SYSTEM where you'll see a real operating system  :)



2) a 3D explanation on RESPIRATION and VENTILATION




3) The video I posted like a year ago in my facebook page about the effects of SMOKING on the Respiratory System:
 


4) Another video about Smoking




I hope the videos are useful and fun to watch (well, fun...not really, maybe just interesting) and to start studying  Don't PROCRASTINATE!!!!!

See you on THURSDAY!!!

PS:And a practical work for next THURSDAY (in pairs). NO COPYING AND PASTING, I WANT THIS IN YOUR OWN NERDY TALK

1) Explain this statement: Players who are born and live at sea level will have a smaller lung capacity than those who spend their life at a high altitude (such as Bolivian players!!)

2) These are the legs who has just finished a Cycling race. Why do they look like this? What for?
