Respiratory System

Respiratory System

The respiratory system supplies oxygen and must work at steady pace to prevent death! The respiratory system has numerous parts such as the nose,pharynx,larynx ,trachea and lungs to name a few.

Nasal

Air enters through the nostrils. Our noses also have nasal cavities which are 2 hollow spaces. When air goes through the nasal cavities, that air becomes warm, filtered & moistened. 

Sinus Cavity

   

Our sinus cavity is by the nasal cavity. 

The sinus cavity provides a lot of things such as warming and softens air and gives us our voice.









The medical term for throat is pharynx. Our pharynx has 3 sections and they are...... the Nasopharynx (upper portion) , the Oropharynx (middle part) and the Laryngopharynx (bottom part).

How are we able to speak?? We can't just tell ourselves to talk. We have a voice box or larynx.
We have vocal cords... whenever the lungs release air our vocal cords vibrate and make sounds. Your tongue and lips help your speech.

Breathing is involuntary because you can control your breathing rate.. Fast/Slow 
There are 2 stages of respiration...
External Respiration & Internal Respiration
Oxygen and your respiration system work together.
