Question

What is the benefit of not having cartilage between the trachea and oesophagus?

Answer 1

Hint:Since the tissues between the passage and trachea area are soft, the passage will bulge into the trachea once you swallow food.The trachea is a passage for air, moistens and warms it whereas it passes into the lungs, associate degreed protects the metabolic process surface from an accumulation of foreign particles. The trachea is lined with a dampish mucous membrane layer composed of cells containing tiny capillary projections known as cilia.

Complete answer:
The open ends of those incomplete rigs are unit directed posteriorly, and swish muscle and connective tissues fill the gaps between the ends. These rubbery rings stop the trachea from collapsing and interfere with the airway. The soft tissues that complete the rings within the back permit the close oesophagus to expand as food moves through it to the abdomen.

The trachea conjointly referred to as the trachea, maybe a duct that connects the cartilaginous structure to the bronchi of the lungs, permitting the passage of air, so is a gift in most body process animals with lungs. The trachea extends from the cartilaginous structure and branches into the 2 primary bronchi. At the highest of the trachea, the cricoid animal tissue attaches it to the cartilaginous structure. The trachea is made by a variety of horseshoe-shaped rings, joined along vertically by ligaments over their substance and by the trachealis muscle at their ends. The cartilaginous structure closes the gap to the cartilaginous structure throughout swallowing.

The larynx, usually referred to as the speech organ or speech organ, is the passageway for air between the throat higher than and therefore the trachea below. It extends from the fourth to the sixth as levels. The cartilaginous structure is commonly divided into 3 sections: sub larynx, larynx, and supra larynx. It's shaped by 9 cartilages that are connected to every different muscle and ligaments.

Note:The cartilage within the cartilaginous tube wall provides support and keeps the trachea from collapsing. The posterior soft tissue permits for enlargement of the oesophagus, that is instantly posterior to the trachea.
