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.
What is the trachea?
Listen to pronunciation. (TRAY-kee-uh) The airway that leads from the larynx (voice box) to the bronchi (large airways that lead to the lungs). Also called windpipe.
What is the function of the trachea and bronchi?
The tubes that make up the bronchial tree perform the same function as the trachea: they distribute air to the lungs . The alveoli are responsible for the primary function of the lungs, which is exchanging carbon dioxide and oxygen.
What is the function of trachea Class 9?
The trachea serves as the main passageway through which air passes from the upper respiratory tract to the lungs .
What is the function of trachea Mcq?
What is the function of trachea? Explanation: Trachea is also known as windpipe. It is a cartilaginous tube that connects the pharynx and larynx to lungs. It filters the air .
What word best describes the function of the trachea?

What is another name for trachea?
Trachea is another name for windpipe , which is the tube that connects your larynx to your primary bronchi, just before your lungs. You can’t breathe without your trachea.

What is the difference between trachea and bronchi?
The main difference between trachea and bronchi is that the trachea is the airway that connects the larynx to the bronchi whereas the bronchi are the two branching airways that lead to the lungs . ... Both trachea and bronchi consist of respiratory mucosa with mucus-secreting cells.
What is the main function of the bronchioles?
The function of the bronchioles is to deliver air to a diffuse network of around 300 million alveoli in the lungs . 5 As you inhale, oxygenated air is pulled into the bronchioles. Carbon dioxide collected by the alveoli is then expelled from the lungs as you exhale.
What is trachea class 10th?
The trachea is a wide, hollow, cartilaginous and tube-like structure located in the neck. It is a part of the respiratory system that connects the larynx (voice box )and larynx to the bronchi of the lungs. The trachea is also known as the windpipe and its length ranges between 10 to 11 cm.
Does the trachea lead to the lungs?
At its bottom end, the trachea divides into left and right air tubes called bronchi (BRAHN-kye), which connect to the lungs . Within the lungs, the bronchi branch into smaller bronchi and even smaller tubes called bronchioles (BRAHN-kee-olz).
Where does the trachea start?
The trachea begins just under the larynx (voice box) and runs down behind the breastbone (sternum). The trachea then divides into two smaller tubes called bronchi: one bronchus for each lung. The trachea is composed of about 20 rings of tough cartilage.
Is respiration a gas exchange?
External Respiration. External respiration is the formal term for gas exchange . It describes both the bulk flow of air into and out of the lungs and the transfer of oxygen and carbon dioxide into the bloodstream through diffusion.
What can cause blockage of the trachea?
The airway can become narrowed or blocked due to many causes, including: Allergic reactions in which the trachea or throat swell closed , including allergic reactions to a bee sting, peanuts, antibiotics (such as penicillin), and blood pressure medicines (such as ACE inhibitors) Chemical burns and reactions.
