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)
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 .
A bronchus (/ ˈ b r ɒ ŋ k ə s / BRONG-kəs; pl.: bronchi, / ˈ b r ɒ ŋ k aɪ / BRONG-ky) is a passage or airway in the lower respiratory tract that conducts air into the lungs.The first or primary bronchi to branch from the trachea at the carina are the right main bronchus and the left main bronchus.
In the mammalian respiratory system, eupnea is normal, good, healthy and unlabored breathing, sometimes known as quiet breathing or a resting respiratory rate. In eupnea, expiration employs only the elastic recoil of the lungs. Eupnea is the unaffected natural breathing in all mammals, including humans.
Respiratory physiology is the biological function of metabolic gas exchange. The complementary category for the anatomical structure of respiratory systems is ...
