The Cricoid cartilage.
The larynx is the organ at the end of the upper respiratory tract (responsible for preventing food and drink going down the airway and contains the vocal chords) the trachea is the first organ in the lower respiratory tract (the windpipe). The thyroid cartilage is located around the mid to lower larynx and the cricoid cartilage links the bottom of the larynx to the top of the trachea. The epithelial cells (internal surface) change from mostly squamous cells (smooth lining) to columnar epithelial cells (many with microscopic hairlike protrusions called cilia).
What else can I help you with?
The upper respiratory tract includes the lungs.?
No, the upper respiratory tract includes the nose or nostrils, nasal cavity, mouth, throat (pharynx), and voice box (larynx).
Which organs make up the upper respiratory system?
The upper respiratory system consists of the nose, nasal cavity, sinuses, pharynx (throat), and larynx (voice box). These organs primarily function to filter, humidify, and warm the air that is breathed in before it reaches the lower respiratory system.
Which canal connects oral and nasal cavities?
The name of the canal is 'Eustachian tube'. It helps to regulate the pressure in the middle ear, when you expect the sound of high intensity. This is done in order to prevent damage to the ear drum. (You contract the whole thorax, when the loud sound is expected.)
The respiratory system subsection is arranged by what site?
The respiratory system subsection is typically arranged by the anatomical site or structure, such as the upper respiratory tract (including the nose and pharynx) and the lower respiratory tract (including the trachea and lungs). This division helps organize information based on the specific parts of the respiratory system being discussed.
Why are goblet cells more numerous in the upper respiratory passages than the lower?
Goblet cells are more numerous in the upper respiratory passages because they help trap and remove particles and pathogens entering the body through the air we breathe. The upper respiratory passages are lined with more goblet cells to provide a protective barrier and aid in the removal of foreign particles.
What connects the upper respiratory organs to the lungs?
trachea .... bronchi
Does a cough clear the upper respiratory passageways?

Is the trachea in the lower respiratory tract?

What is the primary responsibility of the upper respiratory tract?

Where is the trachea found upper and lower part of the respiratory tract?
the upper part of trachea is larynx and lower is two tubes which are bronchi
What separates the upper and lower respiratory?
The hyoid bone.
What are the two medical specialist for the respiratory system?
Pulmonologists treat the lower respiratory system, and otolargyngologists treat the upper respiratory system.
The lungs are part of what?
