The rings prevent collapsing in the absence of air. What kind of epithelium do alveoli have?
Why Are The Cartilage Rings In The Trachea Cshaped Class 11 Biology Cbse
Why do you think the hyaline cartilage rings of the trachea are c shaped rather than o shaped?
Hyaline cartilage rings trachea c shaped. C shape allows room for esophagus to expand. Two or more of the cartilages often unite, partially or completely, and they are sometimes bifurcated at their extremities. The number of rings in the trachea varies from 16 to 20.
Hence, the correct answer is option (d). The rings are generally highly elastic but they may calcify with age. The cartilage of the trachea is considered hyaline cartilage:
100% (2 ratings) answer 1) the hyaline cartilage rings of the trachea are 'c' shaped because it allows the trachea to collapse slightly so that the food can easily pass through the oesophagus. Anatomy and physiology questions and answers. The esophagus lies behind the trachea.
(the cartilaginous rings are incomplete because this allows the trachea to collapse slightly to. [2] two or more of the cartilages often unite, partially or completely, and they are sometimes bifurcated at their extremities. The trachea is surrounded by 16 to 20 rings of hyaline cartilage;
The trachea consists of hyaline cartilage, and most of these cartilaginous rings are partially connected or c shaped, and one or two rings are completely connected, and as the age increases, the cartilage may calcify. Simple, transparent, and made primarily of collagen. This can result in airway stenosis — an abnormal narrowing of your child’s windpipe.
These rings prevent the collapse of the tracheal mucosa during inspiration. Nasopharynx, nasal cavity, trachea, larger bronchiole. Why are the hyaline cartilage rings of the trachea c shaped instead of o?
The anterior portion of the ring is cartilage, while the posterior gap is closed by the trachealis muscle, which is composed of smooth muscle fibers. View the full answer transcribed image text: The function of the cartilaginous rings of the trachea in respiratory system is to stabilize the trachea and keep it rigid while allowing the trachea to expand and lengthen when the person breathes.
This defect in the cartilage can affect one or many of those rings. View full document see page 1 62. Literature guides concept explainers writing.
