Why do pig's bronchi contain cartilage rings?
Many mammals have cartilage rings in their tracheas, which may also extend down the mainstem bronchi. These rings are in place to physically keep the major airways propped open so that air can flow easily.
What is located anterior to the esophagus and carries air to the bronchi?
The trachea splits into the left and right bronchi in the thoracic cavity(the chest). From there the bronchi continue to branch out and keep getting smaller. Kind of like the branches on a tree. At the end of the those branches (bronchioles) are the alveoli( tiny grape like structures). In the alveoli is where the exchange of oxygen and carbon dioxide occur.

Function of cartilage in the respiratory system?
Cartilage in the respiratory system (usually found in the trachea and some small amounts in the bronchi), is to act as a way to keep the passageways open.
What is the role of trachea?
It provides a passageway for air between your larynx and primary bronchi.
What is in the bronchi of the lungs?
two like structures that lead to the lungs and branch off into the broncoe. (trachea) The two main bronchi are formed when the trachea (or windpipe) divides. The right bronchus is more vertical than the left. It is also wider and shorter. It is approximately 2.5cm in length and after entering the right lung it divides into three branches (one going to each of the three lobes of the right lung). Each branch then divides into many smaller branches. As the bronchi get smaller, they are called bronchioles. Bronchioles become terminal bronchioles, then respiratory bronchioles, alveolar ducts.. and finally alveoli. The left bronchus is about 5cm in length and is narrower than the right. After entering the left lung, it divides into two branches (one for each of the two lobes of the left lung). Each branch then divides into smaller bronchi in the same way as the bronchi in the right lung, ending in the alveoli. The bronchi are lined with ciliated columnar epithelium. This contains cilia which are hair like extensions that propel materials along the airways. This helps to keep the airways clear.
How can a person take care of your trachea?
the trachea is a disease
What is your trachea's job?
to keep her smelling
What are bronchi sibdivided into?
bronchi divides in primary bronchi . Which divides in secondary and tertiary.
Are the C-shaped cartilages in the trachea for the expansion of trachea or esophagus?
They are to keep the trachea patent (open) even with low intratracheal air pressures
What are 10 instering facts about the Trachea?
First: it is the "trunk" where air passes through to your bronchus and into your lungs (alveolar duct, alveolar sac, alveolus). Second: the trachea are made up of C-shaped rings of tough flexible cartilage. These rings of cartilage protect the trachea, make it flexible, and keep it from collapsing or over-expanding. Third: is the target for tracheal intubation, a medical procedure, for the critically injured. Allowing a medical provider to secure an open airway. Mainly because the trachea leads straight into the lungs. Forth: Because the trachea is mainly flexible it allows the oesophagus (which is attached to the back of the trachea) to expand when a bolus of food is swallowed. Fifth: The epidermal cells lining the trachea produce mucus which helps to capture things still in the air (fine dust and microbes). This is swept out of the air passageway by tiny ciliary cells, into the throat, where it is swallowed.
Why does the bronchi have cartilage?
To keep them from collapsing due to negative pressure on an exhale.
