They are called the tracheal rings. There are 16-20 of them.

What opens the trachea?
the trachea is held open by rings of cartilages
Why does the trachea have little cartilages?
so that these cartilagenous rings prevent collapsing of trachea
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 types of cartilages are found in the larynx?
Hyaline cartilage, which is an amorphous (chondroitin and glucosamine) matrix that surrounds cells called chondrocytes.This type is found in the embryonic skeleton, costal cartilages, cartilage of the nose, trachea, and larynx. It's function is support, it is avascular and it heals poorly.
What are the names of the paired larynx cartilages?
vocal cords
Which type of connective tissue is found in the trachea and between the ribs and sternum?
The hyaline cartilage forms most of the embryonic skeleton. It also forms coastal cartilages of ribs, cartilages of the nose, trachea and larynx.
What is the function of the rings of the cartilage that surround the trachea in the fetal pig?
to support trachea
Why it is important that the trachea is reinfoced with cartilage rings?
because trachea need support for open all the time and this support is cartilage rings
How does a trachea look likewhy should the trachea be opened all the time?
cartilage rings provides support to the trachea that why it open all the time
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.
What are the two branches of the pulmonary truck?
I am not so sure what are you reffering too: the respiratory system or the trachea alone. But for respiratory system there are two functional parts (1) a conducting system to bring the air in, including the nose, pharynx, larynx, trachea, bronchi and bronchioles; and (2) the respiratory portion, the site of gas exchange, including the respiratory bronchioles, alveolar ducts, alveolar saccules, and alveoli. Trachea: The trachea connects the larynx and bronchi. It is lined with a mucus membrane with respiratory epithelium and a lamina propria, and a submucosa containing horseshoe shape hyaline cartilages and numerous mucus and mixed glands (Trachea 1). The gap between the ends of the cartilages is bridged by fibroelastic connective tissue and smooth muscle (Trachea 2). To increase expandability, the respiratory epithelium is underlaid with a lamina propria containing a distinct elastic lamina (Trachea 3). The trachea is surrounded by an adventitia which is a connective tissue layer shared with the esophagus (Trachea 4). Hope that answers your questions.
In terms of size where does the thyroid cartilage rank in the architecture of the larynx?
The thyroid cartilage is the largest of the nine cartilages that make up the laryngeal skeleton, the cartilage structure in and around the trachea that contains the larynx.
