When air enters the nose, nasal hairs trap dirt particles and dust so that these do not enter the lungs. As air moves further in, it is warmed. Inside the lungs, air expands the lungs and travels downward from the larger bronchi to the smallest bronchioles. At the aveloi, the environmental air delivers a mixture of oxygen and carbon dioxide. The bloodstream, specifically the hemoglobin attached to red blood cells held within blood vessels that surround the aveoli, pick up the oxygen molecules to take those to the body.
In return, the aveloi allows the transfer of carbon dioxide back to the "air" of the last breath that is still inside the lungs. The concentration of carbon dioxide triggers an autonomic neural (brain) reaction that triggers muscles to contract, thus forcing out the air laden with carbon dioxide.
The cycle begins all over again when the brain recognizes a lowering oxygenation level, triggering the intake of another breath.
Note: In lung diseases like emphysema, the brain-lung or oxygen-carbon dioxide feedback system is reversed. Instead of carbon dioxide build-up triggering the need to take a new breath, the diseased lungs work best with higher carbon dioxide, just the opposite from a healthy lung.

Where is the nasal conchea?
The nasal conchae are located inside the nasal cavity on both sides of the nose. They are bony structures covered in mucous membrane that help to increase the surface area in the nasal cavity, which helps to humidify and filter the air we breathe.
List three things that happen to air in the nasal cavity?
Cleaned, moistened, heated
Has 2 turbinates as part of its structure?
The nasal cavity has structures called turbinates, also known as nasal conchae, that help to humidify and filter the air we breathe. There are three pairs of turbinates in the nasal cavity: superior, middle, and inferior. Each pair of turbinates helps to increase the surface area in the nasal cavity, allowing for more efficient warming, humidifying, and filtering of the air.
What are the three major functions of the nasal cavity?
The three major functions of the nasal cavity are to warm, moisten, and filter the air that is inhaled. The nasal cavity also helps to detect and process odors through specialized olfactory receptors. Additionally, it contributes to resonating sound during speech.
How many cavities are in your skull?
There are multiple cavities in the human skull, including the nasal cavity, oral cavity, and cranial cavity, which houses the brain.
Is the choana the same as nasal meatus?
No, the choana is the opening at the back of the nasal cavity that leads to the nasopharynx, while the nasal meatus refers to the three passageways within the nasal cavity that help filter, warm, and humidify inhaled air.
What are the three organs in the respiratory system?
nasal cavity, throat (pharynx), voice box (larynx)The three types of organs of the respiratory systems would be the lungs. However there are the bronchi, trachea, and the diaphragm that work together with the lungs to help us breathe.
What are three organs in your respiratory stystem?
nasal cavity, throat (pharynx), voice box (larynx)
What are the three sections of turbinates?
The three sections of turbinates in the nasal cavity are the superior, middle, and inferior turbinates. They are responsible for filtering, humidifying, and warming air as it passes through the nasal passages.
What are nasal turbinates?
Nasal turbinates are bony structures covered with mucous membranes inside the nasal cavity that help humidify, filter, and warm the air we breathe in. They also play a role in directing airflow through the nasal passages.
Most nasal passages have how many turbinates present on the lateral wall of each nasal cavity?
There are usually three turbinates present on the lateral wall of each nasal cavity - the superior, middle, and inferior turbinates. These bony structures help to humidify, filter, and warm the air as it passes through the nasal passages.
What is the nasal conchae?
The nasal conchae are three pairs of bony projections in the nasal cavity. They are generally curved inferomedially with each roofing a groove or meatus. It helps to filter, heat and moisten inhaled air and minimize heat and moisture loss from the body during exhalation.
