The lower respiratory tract is also called the respiratory tree or tracheobronchial tree, to describe the branching structure of airways supplying air to the lungs, and includes the trachea, bronchi and bronchioles. [8] trachea. main bronchus (diameter approximately 1 – 1.4 cm in adults) [9] lobar bronchus (diameter approximately 1 cm)
The respiratory system (also respiratory apparatus, ventilatory system) is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary ...
This marks the beginning of the terminal respiratory unit called the acinus which includes the respiratory bronchioles, the alveolar ducts, alveolar sacs, and alveoli. [27] An acinus measures up to 10 mm in diameter. [28] A primary pulmonary lobule is the part of the lung distal to the respiratory bronchiole. [29]
The respiratory system is the (anatomical) biological system of any organism that engages in metabolic gas exchange. Even plants have respiratory systems, taking in carbon dioxide and emitting oxygen. This category covers the structure of respiratory systems.

Bronchography is a radiological technique, which involves x-raying the respiratory tree after coating the airways with contrast. [1] Bronchography is rarely performed, as it has been made obsolete with improvements in computed tomography and bronchoscopy .
The highest concentration of blood in the pulmonary circulation occurs in the bases of the pulmonary tree compared to the highest pressure of gas in the apexes of the lungs. Alveoli may not be ventilated in shallow breathing. Shunting may also occur in disease states: Acute respiratory distress syndrome (ARDS). Alveolar collapse, which can ...
A bronchopulmonary segment is a portion of lung supplied by a specific segmental bronchus and its vessels. [1] [2] These arteries branch from the pulmonary and bronchial arteries, and run together through the center of the segment.
