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.

to convert hot/cold air into normal body temperature or as the body requires.
Asked by Lilliana Rogahn in Head, Ears, and Nose, Respiratory System, Winter

Why does cold weather cause runny noses?

User Avatar
A couple different cold-weather factors contribute to there being just too much fluid for the nose to hold (gross, I know, but true). First, because winter air tends to be very dry, the nose has to produce a lot of extra fluid to humidify it properly on its way to the lungs. Sometimes it makes so much that it runs right out the end of the nose. What’s more, when that warm, moisturized air gets breathed back out into cold, dry surroundings, it condenses on the cold tip of the nose, adding even more fluid.

Why the human respiratory system can be thought as a natural pneumatic system?

User Avatar
human respiratory uses air pressure like pneumatic system does
Asked in Grasshoppers, Respiratory System, Similarities Between

What are the similarities between the grasshopper's and human's respiratory systems?

User Avatar
Both the human and grasshopper respiratory systems have structures called trachea that are lined with epithelial cells.
Asked in Conditions and Diseases, Cold and Flu, Respiratory System, Strep Throat

Why are there red bumps in the back of your throat?

User Avatar
A cold usually comes along with other things, sometimes flu, strep throat, etc. and the reason that is is because coughs and colds lower your immune system, the body is fighting the cold and it lowers the immune system allowing other virus's and germs to get in this also includes allergies

How does anaerobic respiration affect respiration?

User Avatar
Anerobic respiration is respiration. Minus the oxygen.

Where Are Cilia in the Respiratory system located?

User Avatar
In the lining of the trachea, bronchi, and bronchioles.
Asked in Respiratory System

Where is inhaled air is warm and moistened?

User Avatar
Inhaled air is warmed and moistened in the nasopharynx and oropharynx.

How does your diaphragm work with other systems to keep the body healthy?

User Avatar
the diaphragm helps move your organs out of the way when you breathe in and pushes the lungs when you breathe out.

Asked in Respiratory System

When you exhale air flows through the respiratory structures in which sequence?

User Avatar
Multiple Choice: A. Alveolus, Bronchiole, Bronchus, Larynx, Trachea, Pharynx, nasal Cavity B. Alveolus, Trachea, Bronchus, Bronchiole, Larynx, Pharynx, Nasal Cavity C. Alveolus, Bronchus, Bronchiole, Trachea, Larynx, Pharynx, Nasal Cavity D. Alveolus, Bronchiole, Bronchus, Trachea, Larynx, Pharynx, Nasal Cavity The correct sequence is Letter D. For all of you who are looking up this question because your anatomy teacher using the Essentials of Human Anatomy and Physiology assigned the stupid Multiple Choice to you, you are so very welcome.
Asked in Respiratory System

What are the main structures of the respiratory system?

User Avatar
The main structures of the respiratory system are: mouth nose pharynx (throat) larynx (vocal cords) trachea (windpipe) bronchi (singular is bronchus; these are the two smaller tubes that are branches of the trachea) bronchioles (even smaller tubes off of the bronchi) lungs alveoli (singular is alveolus; these are tiny sacs on the bronchioles that are surrounded by blood vessels that allow oxygen into the blood)

How high do you need to go until you can not breathe any longer?

User Avatar
You can breathe as long as there is a gas to inhale (about 100 miles) - you wont get enough oxygen to survive however. But the accepted height where you need external oxygen supply is above 14,000'.
