Trachea divides in 2 bronchi which conducte air into the lungs (inside the lungs each bronchi divides in many smaller branchs only studied in college)

No - the hairs inside the nose filter out dust - it's essentially what 'bogies' are made of !

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.

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.

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.

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.

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.

The Primary Bronchi.

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.

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.

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.

That's the epiglottis. It blocks either the trachea or esophagus, depending on whether breathing or eating is happening.

Longitudinal elastic fibers enable the trachea to stretch and descend with the roots of the lungs during inspiration.

the trachea is a disease

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.

Trachea size

toward the throat to be sallowed or spat out

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.

It traps bacteria and dust.
