keuhkoputkiloihin

Keuhkoputkiloihin is a Finnish term referring to the bronchioles, which are the small airways in the lungs that branch off from the bronchi. These delicate tubes play a crucial role in the respiratory system by conducting air to and from the alveoli, the tiny air sacs where gas exchange occurs. The bronchioles are characterized by their lack of cartilage, which distinguishes them from the larger bronchi. They are surrounded by smooth muscle, allowing for their diameter to change, which can influence airflow.

The structure of the bronchioles is important for efficient breathing. As they get smaller, their walls become thinner and their lining changes. This structure facilitates the transfer of oxygen into the bloodstream and carbon dioxide out of the blood. Conditions affecting the bronchioles can have significant impacts on respiratory function. For instance, inflammation and narrowing of the bronchioles, as seen in conditions like asthma and bronchiolitis, can obstruct airflow, leading to symptoms such as wheezing, shortness of breath, and coughing. The health of the bronchioles is therefore vital for maintaining proper lung function and overall well-being.
