Trachea
Also known as the "wind pipe," the trachea is a long, thin-walled, tubular structure, which runs down through neck in front of esophagus.

What are the hair like structures that line the trachea?
Trachea's inner lining(lining that faces the hollow side) is comprised of ciliated epithelium which rests on a basement membrane made of protein fibers.
In between the ciliates cells the goblet cells are situated.
Beneath the epithelium is an area of loos tissue and tracheal glands that secrets mucus (both tracheal glands and goblet cells secrets mucus so don't get confused which one produces mucus).
There is a C-Shaped cartilage in outer lining that supports the trachea.
What the trachea do to help the with digestion?
No. The trachea is part of the respiratory system and is also known as the "windpipe". It carries air to and from the lungs. The esophagus is part of the digestive system and carries food to the stomach. The esophagus runs behind the trachea.
What does smoking do to the cilia in the trachea?
One of the major things that happens is that the tar in the tobacco coats the lungs. If tobacco use continues, tar builds up. This is how tobacco causes cancer - it puts the mouth, throat, and lungs in contact with tar.
What structure guards the entrance to the trachea during swallowing?
That's the epiglottis. It blocks either the trachea or esophagus, depending on whether breathing or eating is happening.
What is the function of elastic fibers in the trachea?
Longitudinal elastic fibers enable the trachea to stretch and descend with the roots of the lungs during inspiration.
Why is the trachea reinforced with cartilaginous rings?
The 'c' shaped cartilage rings are present in the trachea to prevent it from collapsing and they keep the trachea open for air to come in and out. In humans there are about 15 - 20 incomplete C-shaped cartilaginous rings which reinforces the anterior and lateral sides of the trachea to protect and maintain the airway open. (The cartilaginous rings are incomplete because this allows the trachea to collapse slightly to allow food to pass down the esophagus
to give support
The rings of cartilage strengthen the trachea so that it does not collapse, but remains open so that air can get through it.
If It didn't it would collapse in on itself and you would be unable to breathe.
we breath every time so trachea keep open all the time .cartilage rings give support to trachea to open all the time.
The cartilage rings in the trachea keep it from collapsing upon itself with the negative pressure inside of it during inhalation.
The Trachea (also known as the wind pipe) has cartilage rings on it. This prevents the pipe collapsing on itself. If the trachea did collapse, it would disallow us from breathing. Also the trachea might collapse and damage the esophagus (also known as the food pipe) which is behind it.
I'm in Year 8 (or Grade 8 in the (U.S)) and i know that. ;P
It stops it from collapsing when bending the neck, and protects it from tears and other damage.
The trachea (windpipe) has cartilage in it so that it won't collapse when you move your head.
Why does your trachea need to have carrilitage rings?
The trachea has cartilage rings to maintain its structure and keep it open, ensuring that the airway remains clear for unobstructed airflow to and from the lungs. These rings provide rigidity while allowing some flexibility, enabling the trachea to expand and contract during breathing. Additionally, the C-shaped design of the rings prevents the trachea from collapsing, especially when pressure changes occur during activities like swallowing or coughing.
Are the trachea and the throat the same?
A throat is a common name for the hole inside your neck. However, there are two tubes running from your mouth or nose to your stomach or lungs. The oesathagus and the trachea. One tube goes to your stomach with I think is the trachea and the other one allows humans to breathe.
Cilia of the trachea that beat continually propel contaminated mucus where?
toward the throat to be sallowed or spat out
What us the abnormal narrowing of the lumen of the trachea?
Lumen is the internal size or diameter of the trachea (windpipe). Narrowing means that it is smaller for some reason. A main reason for narrowing is inflammation as in asthma or allergies. Narrowing can also happen with intubation as the trachea adapts to the size of the breathing tube over time.
In the lumen of the trachea, this is the area that is in contact with the air coming in.
Cilia are projections on the end of columnar epithelial cells that line the trachea (windpipe), they are responsible for beating (in a 'waving' motion) mucus filled with debris up the trachea out of the lungs and to the epiglottis where it can be swallowed and broken down safely in the stomach.
What is the function of a pig's trachea?
The main function of a pig's trachea is to breathe. It is part of system of passages that allow air into the lungs.
Where is the esophagus located in correspondence with the trachea?
The trachea is right in front and runs parallel with the esophagus.
How are lungs biological adapted for their function on humans?
With each breath, the lungs take in oxygen and remove carbon dioxide.
the lungs have a great surface area thanks to the alveoli; have an extremely thin (1 cell thick) epithelium.
What do the esophagus and trachea do?
The trachea enables the flow of air from the external environment into the lungs to absorb oxygen and other gases.
The esophagus allows the body to ingest food for optimal nutrition and to maintain life processes.
