Keuhkovaltimo is a medical term referring to the bronchial tree, which is the network of airways that branch out from the trachea and lead to the lungs. It is composed of the trachea, bronchi, and bronchioles. The bronchial tree plays a crucial role in the respiratory system by facilitating the exchange of gases between the atmosphere and the bloodstream. The trachea is the largest airway, leading to the bronchi, which further divide into smaller bronchioles. The bronchioles are lined with ciliated epithelial cells that help to clear mucus and foreign particles from the lungs. The bronchial tree is supported by cartilage and smooth muscle, which help to maintain its patency and regulate airflow. Disorders of the bronchial tree can lead to respiratory symptoms such as coughing, wheezing, and shortness of breath. Common conditions affecting the bronchial tree include bronchitis, asthma, and chronic obstructive pulmonary disease (COPD). Treatment options for bronchial tree disorders may include medications, inhaled therapies, and surgical interventions.
