why the rings of cartilage found in trachea of rabbit
Answers
Answer:
The Trachea (Windpipe) in mammals like humans and rabbits is a tube that extends from the lower edge of the larynx to the upper part of the chest above the heart. It has a framework of cartilages to keep it open. These cartilages, shaped somewhat like a tiny horseshoe or the letter C, are found along the entire length of the trachea. All the open sections of these cartilages are at the back (dorsally incomplete) so that the esophagus can bulge into this section during swallowing. The purpose of the trachea is to conduct air between the larynx and the lungs.
Answer:
The cartilaginous rings are incomplete to allow the trachea to collapse slightly so that food can pass down the esophagus . A flap like epiglottis closes the opening to the larynx during swallowing to prevent swallowed matter from entering the trachea.
