What is the trachea?
A tube that connects the larynx to the bronchi, allowing air passage to the lungs.
The trachea is a vital component of the respiratory system.
What are the layers of the trachea?
The trachea consists of three layers:
* Tunica mucosa
* Tunica adventitia
* Hyaline cartilage
These layers provide structural support and facilitate the function of the trachea.
What is the function of the tunica mucosa?
It serves as the inner lining of the trachea, providing a barrier and secreting mucus.
The mucus traps debris and pathogens, aiding in respiratory health.
What is the role of hyaline cartilage in the trachea?
Hyaline cartilage provides structural support and maintains the shape of the trachea.
This prevents the trachea from collapsing during breathing.
Fill in the blank: The outer layer of the trachea is called the _______.
Tunica adventitia
The tunica adventitia anchors the trachea to surrounding tissues.
What is the significance of mucous glands in the trachea?
They produce mucus, which helps trap particles and pathogens, keeping the airways clear.
Mucous glands play an essential role in the respiratory defense mechanism.
True or False: The trachea is supported by rings of elastic cartilage.
False
The trachea is primarily supported by hyaline cartilage, not elastic cartilage.
What is the function of the ciliated epithelium in the trachea?
It helps move mucus and trapped particles out of the airways toward the throat.
The cilia beat in a coordinated manner to clear the airways.
What is the term for the muscle that controls the trachea’s diameter?
Musculus trachealis
This muscle allows for adjustments in airflow and resistance.
