A Mucous Membrane - Cylindrical With A Vibrating

a mucous membrane - cylindrical with a vibrating layer its Constant oscillative motions - promote advancement of small dust particles and formed slime in a throat direction. Trachea blood supply is carried out by branches of the bottom thyroid arteries and branches of the bronchial arteries originating from the descending aorta or the top intercostal arteries The blue blood flows mainly in venous textures, round a trachea and a gullet, whence arrives in the bottom venous textures of a thyroid gland, unpaired and semiunpaired veins. Outflow of a lymph from a trachea goes in centripetal a direction. Ways of outflow of a lymph from a trachea are closely connected with lymphatic ways of a gullet, a throat, a thyroid gland. tracheas it is carried out by branches returnable and nerves Besides, the trachea has sympathetic and parasympathetic the Part of nervous fibres spinal (from With, to Dg) Distinguish cervical and chest departments of a trachea. Last divide on chest and parts a trachea Arrangement on a neck and in a chest cavity causes its interrelations with neck and thorax bodies On a neck in front of it cover a thyroid gland isthmus, forward thyroid veins, sideways - shares of a thyroid gland and carotids ( carotis), behind a gullet with the returnable nerves lying in a furrow between a gullet and a trachea In chest department in front of a trachea the beginning of an anonymous artery (and ) and the left carotid, behind a gullet, at the left an aorta arch, the left general carotid, the left returnable nerve, on the right - an anonymous artery, the right wandering nerve is located.
