Question

Rings of cartilage are not present in oesophagus but present in trachea ? why?

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.Normally, the epiglottis keeps food and drink from going down the windpipe. This sturdy flap of cartilage is designed to snap shut automatically when we swallow, closing off the airway and shunting the sustenance down the esophagus to meet itsdigestive fate.It is commonly referred to as the throat. The pharynx is part of both the digestive and respiratory systems. For the digestive system, its muscular walls function in the process of swallowing, and it serves as a pathway for the movement of food from the mouth to the esophagus.
