Respiratory System
The respiratory system includes the lungs and the airway. The questions in this category focus mainly on the anatomical and physiological processes associated with breathing.

What happens to a oxygen molecule when it passes through the trachea?
When an oxygen molecule passes through the trachea, it travels through the airway as part of the respiratory process. The trachea, lined with cilia and mucus, helps filter, warm, and humidify the air before it reaches the lungs. As the oxygen continues into the bronchi and eventually the alveoli, it is prepared for gas exchange, where it will diffuse into the bloodstream to be transported to cells throughout the body.
What does respiratory system do?
Oxygen is passed through the lungs to bring oxygen to the blood to be passed through the heart and keeps oxygenating it.
Larynx is a valve structure between the windpipe and the throat that is an organ of voice production
Is there a respiratory therapist to paramedic bridge?
yes there is one in Texas.. Brookhaven College contact David Dunafan.
What supports the respiratory system provide for cells?
the respiratory system provides oxygen for them
What is the difference between respiratory system of mammal and fish?
Mammals use lungs to collect oxygen from the air, fish use gills to collect oxygen from the water.
What functions is the pontine respiratory group responsible for?
it terminates inspiration and effects tidal volume. it directs the amount of air a person can breathe in. It signals the DRG to increase breathing rate when we need to breathe faster and can allow for breathing to slow down. This function is found in the stretch receptors of lungs in the respiratory system (redundunt feature).
What is the importance of appropriate airway management in a patient with an altered mental status?
If a person has an altered mental state, they could be poisoned, suffering brain injury, hypoglycemic, drugged, suffering lung problems, or suffering any of various other illnesses. So you have to make sure their breathing and heart rate are stable to help buy time to diagnose the underlying problems.
If a person is drugged or intoxicated and unconscious, they could aspirate their own vomit. That could lead to pneumonia or suffocation. Or they could smother. Also, it is possible that whatever is causing an altered mental state may also cause breathing difficulties.

What is the pathway of air through respiratory system?
At the back of the nose and throat lies the pharynx. The pharynx is further divided into the nasopharynx, oropharynx and layrngopharynx (aka hypopharynx).
The nasopharynx from the base of the skull to the soft area at the roof of the mouth (soft palate). The sides of the nasopharynx are open and contain the sustachian tubes. Tonsils and adenoid are at the top of the nasopharynx.
The oropharynx connects with the soft palate, travelling to the epiglottis (the valve that stops us from inhaling food, and closes when we drink and eat). The oropharynx communicates with the respiratory and digestive system.
The laynrgopharynx begins at the epiglottis and and extends to the esophagus.
Next comes the larynx, and now we're starting to enter the airways. The larynx connects the upper and lower airways. Then there's the trachea, mainstem bronchi, lobar bronchi, segmental bronchi, and subsegmental bronchi - all divisions within the lungs of the bronchial tubes.
Now things get smaller. Further down are the bronchioles, or small airways. This is were we start to get air. The bronchioles are the source of oxygen delivery.
At the very end, in the terminal bronchioles, air conduction (not exchange) ends.
We're almost there. The respiratory bronchioles are the very beginning of where we exchange air, taking in oxygen and blowing out carbon dioxide
Mouth --> Pharynx --> Larynx --> Trachea --> (LUNGS: Bronchus --> Bronchioles --> Alveoli), then back out.
What makes up the skin of the body and the lining of the respiratory and digestive tracts?
The Epithelium
Alveoli of the lungs have which kind of cell arrangement?
Stratified: I disagree with stratified, the answer is "simple" arrangement.
How much carbon dioxide does a human exhale?
It depends on age, gender and activity but on average a human exhales 1 KG per day?
If you are thinking of global warming, then the carbon dioxide exhaled by humans (and animals) does not contribute to global warming. The carbon we exhale was taken from the world very recently, so breathing is part of the carbon cycle.
Alot.
What does the trchea do in the respiratory system?
The trachea is the fancy name for the airway. Air passes through the trachea on its way to the lungs. Also after your body uses all the oxygen in the air you breathe your diaphragm will force your body exhale the waste after your body breathes the waste is a gas mainly C02.
The diaphragm expands and contracts automatically, forcing air into and out of the lungs.
What is 1 organ found in the respiratory system?
One organ found in the respiratory system is the lungs. The lungs are responsible for the exchange of oxygen and carbon dioxide between the air and the bloodstream. They facilitate breathing by expanding and contracting, allowing air to flow in and out. Additionally, the lungs play a crucial role in maintaining the body's pH balance and overall respiratory health.
