breathe.

okay okay.

the respiratory system composes of nose, pharynx, trachea, bronchi and lungs. this system, with the cardiovascular system, is collectively known as cardiopulmonary system since they compliment each other regarding the collection and transportation of oxygen throughout our body. honestly, i didn't understand this from the reporter. at the same time, my head got short circuit, resulting to overstress and fatigue that make me no interest on the topic anymore. anyway, where am i? oh. lungs are cone-shaped organs that takes up the most space in our chests. in it happens the exchange of gases and wastes to the blood and vice versa. what our body needs in order to live is the oxygen. but everything has its by-product after it was processed. in our case, the by-product is the carbon dioxide. in lungs, as oxygen approaches the lungs, particularly in capillaries, carbon dioxide go out from the blood to the lungs and be transported out from the system. btw. ventilation is different from respiration. when we say ventilation, it is the process where air fills our lungs. on the other hand, respiration is the process where the actual exchange happens. interesting? i got twisted by this terms, too.

duh, right.

i will explain this with the use of an aspirator, the one used in cleaning keyboards, etc. ? i will continuosly press and release it to let the one who doesn't understand can understand how we breathe. series of careful explanation, non-ending drills, and powerful discussions [not angry-wise. :) ]

ows?

if i were the teacher, i would be in front of them and give them inhale-exhale procedures. after that, we will have some discussions on how everything in the respiratory system works. :)
