Earrann Trachea

Tha an rud seo air a dhèanamh suas de 3 mhodalan eadar-dhealaichte air an aon bhunait: tha a ’chiad fhear ag ath-riochdachadh crois-earrann meud beatha 3X den trachea daonna; faodar a roinn gu fada ann an dà phàirt gus an anatomy a-staigh a nochdadh. Is e an dàrna modail leudachadh air crois-earrann balla trachea anterior; tha e a ’sealltainn a h-uile diofar shreath, bhon cartilage tracheal chun an epithelium. Tha an treas fear a ’sealltainn an epithelium leudaichte pseudostratified cliated gu mionaideach: tha e a’ taisbeanadh na ceallan ciliated tipical agus ceallan mucous.
