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.

Is it true that trachea filters dust?
No - the hairs inside the nose filter out dust - it's essentially what 'bogies' are made of !
Does the trachea enter the lungs?
According to a figure in my human biology book if the trachea and the Bronchus is made out of the same matter then the Trachea does enter the lung. Unless the bronchus is made out of unique tissue muscle etc.
What is a another name for the windpipe and how does it differ from esophagus?
The other name is the trachea. It is part of the respiratory system and helps to take air in and out of the lungs. The esophagus is a tube that leads to the stomach and is part of the digestive system.
What is the name of the 2 cartilage ringed tubes that carry air from the trachea to the lungs?
The two tubes that carry air from the trachea to the lungs are called bronchial tubes
The bronchial tubes. As these tubes pass through the lungs, they divide into smaller passages called the bronchioles. The bronchioles end in air sacs called alveoli.
Why is the trachea rigid and the esophagus flat and muscular?
The trachea is structured in a way so that an individual can breathe at all times (in/voluntarily). The tracheal rings allow the trachea to stay open so that a person can breathe. The esophagus is flat b/c it is strictly for the passage of food, so it is not used as often as the trachea.
Are the rings cartilage in the trachea incomplete dorsally or ventrally?
The cartilaginous rings in a pigs trachea are incomplete. These rings are responsible for supporting the trachea of the pig when it breathes in and out. Without these rings the pig would be in danger of having their throat collapse.
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.
