keuhkoputkesta

Keuhkoputki, also known as the bronchus, refers to the airways that lead from the trachea (windpipe) into the lungs. These are essential passageways for air to travel to and from the gas exchange surfaces within the lungs. The trachea divides into two main bronchi, the right and the left, which then further subdivide into smaller and smaller tubes. These branching airways are known as bronchioles. The walls of the bronchi are composed of cartilage, smooth muscle, and a mucous membrane lining. This lining helps to trap inhaled particles and pathogens, which are then moved upwards and out of the respiratory system by tiny hair-like structures called cilia. The cartilage provides structural support, preventing the airways from collapsing. As the bronchi branch into smaller bronchioles, the amount of cartilage decreases, and the proportion of smooth muscle increases. Inflammation or obstruction of the keuhkoputket can lead to various respiratory conditions, such as bronchitis and asthma. Understanding the structure and function of the keuhkoputki is crucial for comprehending the mechanics of breathing and diagnosing respiratory illnesses.
