Английский язык для медиков: конспект лекцийSubmucosa consists of dense elastic connective tissue with serorilt-fcous glands whose ducts open onto the surface of the epithe lium. Cartilage rings are C-shaped hyaline cartilage pieces whose free extremities point dorsally (posteriorly). They are covered by a pe-richondrium of fibrous connective tissue that surrounds each of the cartilages. Smooth muscle bundles (trachealis muscle) and ligaments span the dorsal part of each cartilage. Adventita a consists of peripheral dense connective tissue that binds the trachea to surrounding tissues. Primary bronchi The trachea branches at its distal end into the two primary bronchi. Short extrapulmonary segments of the primary bronchi exist before they enter the lungs at the hilus and then branch further. The histologic structure of the walls of the extrapulmonary segment of the primary bronchi is similar to that of the tracheal wall.
