The segments are subdivided into lobules (about 1,000 per lung). The lobules are 9–27 mm high, depending on whether they are located on the surface of the organ or deeper within it. The intralobular bronchi divide into bronchioles. These bronchioles, in turn, continue branching to become ...
The right main stem bronchus divides into the ___, ___, and ___ lobar bronchi. Bronchi: The broncho is structure of the airway that connects the esophagus to the lungs. Once the air has reached the lungs through these structures, it enters into successively smaller ...
Tertiary bronchi divide into: a) secondary bronchi. b) bronchioles. c) alveolar ducts. d) alveoli. Which of the following organs is not part of the upper respiratory tract? a. trachea b. pharynx c. larynx d. nasal cavity What is the anatomical location of the lungs?

The only tissue in the lungs apart from the alveolar membranes and the tissues of blood vessels, bronchi and bronchioles, is the small amount of fibrous and elastic tissue that supports the alveoli. Ventilation also is greatest at the base of the lungs and least at the apices but the ...
The respiratory tract is divided into upper and lower regions at theepiglottis. Air enters the upper respiratory tract through thenasal cavityand mouth, which both lead to thepharynx. The lower respiratory tract extends from thelarynxinto thetracheabefore branching into thebronchi, which divide furthe...
and second-order branches, usually less developed, form below the top of the main axis. These branches can also divide into third-order branches and so on. This type of branching is peculiar to spruce, pines, and other coniferous plants, to many herbaceous plants, to leafy mosses, and othe...
These bronchi split into secondary and tertiary bronchi as the lobes of the lungs. These finally split into smaller bronchioles until they become the respiratory bronchioles. The respiratory bronchioles supply air through alveolar ducts into the alveoli, which are the main place for exchange of the ...
Bronchi are the main passageways from the trachea into the lungs, while bronchioles are smaller tubes branching from the bronchi, facilitating airflow. Both are essential for respiration.
