bronchus

The structures that make up the posterior respiratory system of boto and tucuxi were evaluated macroscopically at the UFAC's Laboratory of Animal Anatomy (Center for Biological and Nature Sciences) and the following biometric parameters were taken: length, width and thickness of the components of the trachea, tracheal bronchus, main bronchi and lungs.

The signs of stable vascular alteration of the respiratory tract in case of bronchial remodeling are determined by their hypertrophy and angiogenesis manifested by 2-3 times increased number of vessels in the area of small and middle-size bronchi.

In the Group I, the initial development of the bronchi and bronchioles was observed in the lung parenchyma, which were surrounded by abundant fetal mesenchyme and blood vessels (Figures 2A2C), typical characteristics of the pseudoglandular stage.

It is about 60 cm long that terminates by bifurcation into two (right and left) bronchi at base of heart which enter into corresponding lung (Ghosh, 2009).

A high-resolution chest CT showed enlarged trachea and main stem bronchi (trachea with both sagittal and axial dimensions of 2.

5 cm in diameter and the right and left main bronchi measured 2.

When foreign bodies are stuck in the bronchi for a long time, various complications such as atelectasis, chronic lung infection, abscess, and bronchiectasis may develop (2).

Since bronchi are similar to blood vessels in appearance, surgeons cannot directly touch and feel the tissue under thoracoscope.

In addition, people with asthma have inflamed airways which cause two secondary symptoms one of which contain the bronchi, the airway branches leading to the lungs, and the other, lungs.

A variety of neoplastic, inflammatory and congenital diseases may affect the trachea and mainstem bronchi.

Both the right and left tracheal bronchi have a high association with cardiovascular and costovertebral defects.

Bronchiectasis is a condition in which the elastic and muscular components in the walls of medium-sized bronchi are permanently destroyed, causing persistent coughing and difficulty breathing.

The doughnut sign visualised on the lateral chest radiograph is formed by the normal right and left main pulmonary arteries and the posterior aspect of the aortic arch anteriorly and superiorly and hilar and subcarinal lymphadenopathy inferiorly, with the central radiolucent centre formed by the trachea and upper lobe bronchi (1-3) (Fig.

A Bronchitis is an infection of the main airways of the lungs, which are known as the bronchi.

The source of a chronic cough that is dry or rasping, he notes, will usually be in the upper respiratory system or trachea, while a cough that sounds deep and moist would probably be coming from the bronchi or the lungs.
