The respiratory system cannot function without the windpipe.
Smoking will hurt the respiratory system. It has harmful lead, so when you inhale you are inhaling lead.
The Respiratory System does that work.
The respiratory system inhales oxygen from the air we breathe in, and exhales carbon dioxide as waste.
The most common use of the respiratory system is the exchange of gases. When you exhale carbon dioxide, at the same time you inhale oxygen.
how can respiatory system respond to internal and external stimuli
You inhale due to expanding and contracting your diaphram. The respiratory system provides oxygen to your blood, and expells waste gases such as carbon dioxide.
It goes through your respiratory system, and into the blood stream, where the oxygen takes the place of 'old oxygen', which has been converted to carbon dioxide, and you breath out the carbon dioxide. That is repeated with each breath.
When we inhale, the air enters our respiratory system and gets warmed and humidified, which increases its moisture content. As we exhale, the air has picked up moisture from our lungs and respiratory tract, leading to a higher water vapor content compared to the air we inhale.
The Respiratory System allows your body to inhale and exhale air. It's role is to supply the blood with oxygen. That is accomplished by breathing, that is, inhaling oxygen and exhaling carbon dioxide.
nicotine is a dangerous "drug" that damages the respiratory system , specifically the lungs . So, If a person does not smokes , and does not inhale "secondhand smoke" , his/her respiratory system will be healthy... facebook : lizie_aquino@yahoo.com twitter : @leezey27
