What is the function of the larynx and trachea?
Larynx, also called voice box, a hollow, tubular structure connected to the top of the windpipe (trachea); air passes through the larynx on its way to the lungs. The larynx also produces vocal sounds and prevents the passage of food and other foreign particles into the lower respiratory tracts.
What is difference of larynx and trachea?
Larynx — also known as the voice box, the larynx is a cylindrical grouping of cartilages, muscles and soft tissue that contains the vocal cords. The larynx is the upper opening into the windpipe (trachea), the passageway to the lungs.
How does the larynx protect the trachea?
The larynx has a kind of lid to prevent food from entering the windpipe and lower airways: This lid is called the epiglottis. It is attached to the top part of the larynx, where it can close the entrance to the larynx. When we swallow, it moves down to keep any food or liquids out of the windpipe.
What is the transition between larynx and trachea?
The cricoid cartilage is the most inferior structure of the larynx and forms the transition between the larynx and the trachea. It is ring-shaped, with its widest portion facing posteriorly and its narrowest portion facing anteriorly.
What is the main function of trachea?
The trachea serves as passage for air, moistens and warms it while it passes into the lungs, and protects the respiratory surface from an accumulation of foreign particles. The trachea is lined with a moist mucous-membrane layer composed of cells containing small hairlike projections called cilia.
What is main function of larynx?
The larynx serves to protect the lower airways, facilitates respiration, and plays a key role in phonation. In humans the protective and respiratory functions are compromised in favor of its phonatory function.
What comes first trachea or pharynx?
The larynx, commonly called the voice box or glottis, is the passageway for air between the pharynx above and the trachea below. It extends from the fourth to the sixth vertebral levels.

What is the main function of larynx?
Key Points The larynx serves to protect the lower airways, facilitates respiration, and plays a key role in phonation. In humans the protective and respiratory functions are compromised in favor of its phonatory function.
What’s the function of trachea?
Is your trachea on left or right?
The trachea, commonly called the windpipe, is the main airway to the lungs. It divides into the right and left bronchi at the level of the fifth thoracic vertebra, channeling air to the right or left lung. The hyaline cartilage in the tracheal wall provides support and keeps the trachea from collapsing.
Which tube carries the air from the larynx into the lungs?
When you inhale through your nose or mouth, air travels down the pharynx (back of the throat), passes through your larynx (voice box) and into your trachea (windpipe). Your trachea is divided into 2 air passages called bronchial tubes. One bronchial tube leads to the left lung, the other to the right lung.
