respiratory zone is from respiratory bronchioles (generation 17-19) to alveolar ducts (generation 20-22) to alveolar sacs (generation 23). It is the site of gas exhange, where velocity of gas is low, and diffusion is the dominant mechanism of gas exchange.

Why do you think the bronchial tree segments are functionally separate regions in each lung?

Because the bronchial tree needs to divide the oxygen into diffrent parts of the lungs.


Why is the bronchial tree called the bronchial tree?

The bronchial tree is called so because its structure resembles that of a tree, with the main trachea branching out into smaller bronchi and bronchioles, similar to the branches of a tree extending from the trunk. This branching structure helps in distributing air to the lungs efficiently.


Hat is the smallest branches of the bronchial tree in a cat?

The smallest branches of the bronchial tree in a cat are bronchioles.


What makes up the bronchial tree?

The bronchial tree includes the trachea, bronchi, and bronchioles. Pimary Bronchi, Secondary Bronchi, Tertiary Bronchi, and Smaller Bronchi.


Does pleura cover bronchial tree?

No, the pleura does not cover the bronchial tree. The pleura is a double-layered membrane that surrounds the lungs and lines the chest cavity, while the bronchial tree consists of the branching airways that lead to the lungs. The outer layer of the pleura, known as the parietal pleura, lines the thoracic cavity, and the inner layer, the visceral pleura, adheres to the surface of the lungs, but does not extend into the bronchial tree itself.


Which is the Airway connecting the larynx to the bronchial tree is?

Trachea


What branches out as it enters the lungs?

It's called the "bronchial tree".


Why are the bronchial tree segments functionally separate in each lung?

The bronchial tree segments are functionally separate in each lung to maximize airflow distribution and optimize gas exchange. This segregation allows for efficient ventilation of all areas of the lung and helps to prevent the spread of infection or damage to one lung affecting the other. It also allows for better control of air distribution during inhalation and exhalation.


What is the bronchial?

The term 'bronchial tree' refers to the inner workings of the lungs. It includes the bronchi, bronchioles, and alvioli, all of which are necessary for breathing.


Where would you look for a bronchial tree?

In the chest. It is the sum of all bronchial tissue from the start of the trachea to the last divisions in the lung before the alveoli.


Where do the branches of the bronchial tree ultimately end?

The branches of the bronchial tree ultimately end in the alveoli, which are tiny air sacs in the lungs. These alveoli are the sites of gas exchange, where oxygen is absorbed into the blood and carbon dioxide is released. The bronchial tree includes primary bronchi, secondary bronchi, tertiary bronchi, and smaller bronchioles, leading to these alveolar structures.


What is the bronchial tree?

The bronchial tree is the "plumbing" of the lungs, tubes carrying air to and from the alveoli where oxygen and carbon dioxide exchange actually take place. It looks like tree with many branches of overlie and it help pass the oxygen in and the carbon dioxide out.
