No, cartilage is only contained up until the bronchi. The bronchioles and onward do not contain any cartilage rings, only smooth muscle.

∙ 11y agoNo, bronchioles do not contain cartilage (except in the whale).
The trachea has cartilage rings and the bronchi have cartilage plates.

Bronchioles are kept open by?
rings of cartilage
The bronchioles lack the support of what?
Cartilage rings that are found in trachea
What is the diffirence of bronchi and bronchioles?
Very small bronchi are called as bronchioles. You have cartilage rings in case of the bronchi. Such rings are absent in case of the bronchiloles. You need such C shaped cartilage rings in case of bronchi, so that they should not get collapsed. The bronchioles are in periphery and they can not collapse because they are very small muscular tubes. C shaped cartilage saves lot of muscle mass of the bronchi to prevent them from collapsing.
Which type of bronchioles don't have cartilage?
Bronchioles don't have cartilage because they need to be able to constrict and dilate
How are the bronchial tubes and the trachea similar?
The trachea contains cartilage rings and mucous glands. The bronchioles contain no cartilage and no mucous glands. Bronchioles contain Clara cells (that the trachea does not). Respiratory bronchioles contain alveoli, which are very thin-walled blind ending sacs where gas exchange occurs - these are not present in the trachea.
Do the bronchioles have cartilage support?
trachae is lined by u shaped hyaline cartilages all through its length (from c6 to t4),the posterior free ends of the cartilage are bridged by the trachealis musle.
Why trachea never collapse when there is insuficient air in it?
cartilage rings give support to trachea to open all the time
Why bronchi have rings of cartilage?
Think about this one for a minute. Would it be a good idea for the windpipe to fold up like a garden hose every time you bend your head? What would happen if your air supply was cut off every few seconds? The cartilage keeps the trachea and bronchi open at all times.
Which has more cartilage the primary bronchi or the bronchioles?
primary
What lacks the support of cartilage in the respiratory system?
THE BRONCHIOLES
Which organ of respiratory system do not contain cartilage?
the bronchioles
The changes that occur as the bronchial tree gets smaller are what?
Support structures change: irregular plates of cartilage replace the cartilage rings, and by the time the bronchioles are reached, the tube walls no longer contain supportive cartilage. Epithelium type changes: the mucosal epithelium things as it changes from pseudostratified columnar to columnar and then to cuboidal in the terminal bronchioles. Mucus-producing cells and cilia are sparse in the bronchioles. For this reason, most airborn debris found at or below the level of the bronchioles must be removed by macrophages in the alveoli. Amount of smooth muscle increases: the relative amount of smooth muscle in the tube walls increases as the passageways become smaller. A complete layer of circular smooth muscle in the bronchioles and the lack of supporting cartilage (which would hinder construction) allows the bronchioles to provide substantial resistance to air passage.
