Bronchioles Terminal

Terminal bronchioles (b.terminales, lnh) are small bronchi, which are the final branch of the bronchial tree. They are located in the lungs and are the last link of the respiratory system.

Bronchioles have a diameter of less than 1 mm and are small branches that branch into smaller bronchi. Terminal bronchioles perform an important function in the body as they enable gas exchange between air and blood in the lungs.

In the lungs, the terminal bronchioles are located directly next to the alveoli - small air sacs where gas exchange occurs between blood and air. Due to their structure, bronchioles provide maximum surface area for gas exchange, which allows for increased breathing efficiency.

In addition, terminal bronchioles play an important role in the body's immune system. They contain large numbers of immune cells such as macrophages and lymphocytes, which protect the lungs from infections and other pathogenic agents.

However, in some diseases, such as bronchitis or pneumonia, the terminal bronchioles can be damaged and lead to impaired gas exchange in the lungs. This can lead to serious complications such as respiratory failure or even death.

Thus, the terminal bronchioles are an important part of the respiratory system and play an important role both in the process of gas exchange in the lungs and in the body’s immune defense. However, with certain diseases, they can be damaged, which can lead to dangerous consequences.
