The cartilage rings in the trachea need to be C shaped so large masses of food can pass through the esophagus during swallowing and large masses of air can pass through the trachea.
To allow the oesophagus to expand so that large pieces of food are able to move down into the stomach without getting stuck and tearing the walls of the oesophagus.

What tissue forms the larynx?
The larynx is primarily composed of cartilage, specifically the thyroid, cricoid, and arytenoid cartilages. These cartilages are supported by connective tissue and muscles, which give structure and facilitate movement within the larynx.
Which type of connective tissue is found in the trachea and between the ribs and sternum?
The type of connective tissue found in the trachea and between the ribs and sternum is hyaline cartilage. Hyaline cartilage is a smooth and flexible type of connective tissue that provides support and reduces friction between bones.
Where are elastic Cartilages located at?
Cartlage, (elastic), conects bone to bone, ligaments, (non-elastic), connect muscle to bone.
A 12-cm tube located below the larynx is the?
That tube is the trachea.
What are the structure at the level of the sternal angle?
Bifurcation of trachea, start and finish of the aortic arch, arch of azygos vein, 2nd costal cartilages, intervertebral disc between T4 and T5. It also separates the superior mediastinium from the inferior mediastinium.
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
What are the names of the cartilages that support the trachea?
They are called the tracheal rings. There are 16-20 of them.
Are the C-shaped cartilages in the trachea for the expansion of trachea or esophagus?
The C-shaped cartilages in the trachea are specifically designed to provide structural support and prevent collapse of the trachea during breathing. They do not serve a purpose in the expansion of the trachea or esophagus.
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 is the medical term meaning forming an opening (mouth) in the trachea?
It's called a tracheotomy.
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.
What term means forming an opening in the trachea?
The term for forming an opening in the trachea is "tracheostomy." This surgical procedure involves creating an incision in the trachea to establish an airway, often used in situations where the normal breathing pathway is obstructed or compromised. It allows for direct access to the airway and can facilitate breathing in patients with severe respiratory issues.
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.
What tissue forms the larynx?
The larynx is primarily composed of cartilage, specifically the thyroid, cricoid, and arytenoid cartilages. These cartilages are supported by connective tissue and muscles, which give structure and facilitate movement within the larynx.
Which type of connective tissue is found in the trachea and between the ribs and sternum?
The type of connective tissue found in the trachea and between the ribs and sternum is hyaline cartilage. Hyaline cartilage is a smooth and flexible type of connective tissue that provides support and reduces friction between bones.
Why are the cartilages rings incomplete?
This is very good question. Which haunted me for decades. If you have no cartilage, then your larynx and bronchi will collapse. If you have full cartilage ring, then your bronchi can not get constricted. Incomplete rings of cartilage has solved the problem. Your bronchi and trachea do not collapse and can constrict also.
