Club cells:These cells in the lining of the bronchioles secrete surfactants, substances that reduce surface tension within airways. This allows the airways to expand during inhalation, preventing them from collapsing during exhalation.4Club cells also secrete enzymes that break down debris and irritants...

Bronchi:The trachea bifurcates into two bronchi, leading to the right and left lungs. These bronchi further divide into smaller bronchioles, forming an intricate network that conducts air into the lungs. Lung:The lungs are the primary respiratory organs, located within the thoracic cavity. Comprisi...
Definition (MSH) The larger air passages of the lungs arising from the terminal bifurcation of the TRACHEA. They include the largest two primary bronchi which branch out into secondary bronchi, and tertiary bronchi which extend into BRONCHIOLES and PULMONARY ALVEOLI. Definition (NCI) Tubular structure...

The trachea, bronchi, and bronchioles are known as the bronchial tree because it looks like an upside-down tree. The trachea is the trunk, the bronchi are the limbs, the bronchioles are the branches, and the alveoli are the leaves. Carina The bronchi begin at the bottom of the trachea...
Bronchioles finally terminate in clusters of small air sacs known as alveoli. The oxygenated blood is taken into the blood by the alveoli. Carbon dioxide, a metabolic waste product, flows from the blood to the alveoli, where it is released. The interstitium is a delicate layer of cells that...

The tissue of the bronchiole walls allows the diameter of bronchioles to change to a significant degree. When the body requires greater volumes of air entering the lungs, such as during exercise, the bronchioles dilate to permit greater airflow. In response to dust or other environmental ...
