We describe a method for the detection of tumor nodule development in the lungs of an adenocarcinoma mouse model using micro-computed tomography and its use for monitoring changes in nodule size over time and in response to treatment. The accuracy of the assessment was confirmed with end-point histological quantification.

In this video, we demonstrate the tracheal intubation — an invasive procedure for insertion of an endotracheal tube through the mouth in a rabbit model. This procedure allows for mechanical ventilation of the lungs.
FAQs
The airway hierarchy distributes inhaled air progressively through primary, secondary, and tertiary bronchi before it reaches the bronchioles. This repeated branching creates an organized pathway through the lungs and provides the structural framework needed to connect the trachea with the smaller air passages involved in ventilation and gas exchange.
These components support different aspects of airway function. Cartilage helps maintain the bronchi's structure, smooth muscle contributes to regulation of airflow, and mucus-producing tissue traps inhaled particles. Together, they help preserve an effective passage for air while contributing to airway protection and control.
The transition marks a progressive change from larger, structurally supported air passages to smaller branches within the airway network. Following this sequence helps researchers relate bronchial anatomy to the distribution of air throughout the lungs and to the pathways that ultimately support gas exchange.
Bronchi are examined as part of respiratory anatomy, airway defense, and the organization of lung ventilation. Their branching pattern and structural components provide a framework for biological study, while diagnostic imaging can investigate this airway architecture. This information supports research into normal respiratory function and conditions affecting airway patency.
Diagnostic imaging can help visualize the bronchial framework and its continuation into progressively smaller air passages. By relating visible airway structure to respiratory anatomy, researchers and clinicians can study how the bronchial network is organized and investigate changes associated with airway disorders such as bronchitis and asthma.
Because the bronchi participate in airflow regulation, particle trapping, and the organized delivery of air into the lungs, they provide an important anatomical context for studying airway disorders. Research focused on bronchial structure and function can support understanding of bronchitis and asthma, as well as development of treatments intended to improve airway patency.
