Question

What is location and funation of trachea?

Answer 1

Trachea (Windpipe)
The trachea (or windpipe) is a wide, hollow tube that connects the larynx (or voice box) to the bronchi of the lungs. It is an integral part of the body's airway and has the vital function of providing air flow to and from the lungs for respiration.

The trachea starts where the larynx ends – at the level of the C6 vertebra – and run down the middle of the neck anterior to the esophagus. Function of the Trachea

• The primary function of the trachea is to allow air to pass between the larynx and bronchi. It allows the air to be divided and routed into both lungs by terminating into the two main bronchi.
• The ciliated respiratory epithelium also traps dust particles in the air and propels it out of the respiratory passages, towards the pharynx (throat).
• The trachealis muscle that joins the two ends of the tracheal ring can contract thereby constricting the tracheal tube. This is useful for increasing the pressure during coughing to evacuate any irritants more effectively.
