Bronchi and bronchioles
http://en.wikipedia.org/wiki/Lung
The two main tubes through which air flows when you breathe are the trachea, also known as the windpipe, and the bronchial tubes, which branch off from the trachea and lead to the lungs.
The main five parts of the lung are included in the next sentence. The parts are the bronchial tree, larynyx, aveoli, trachea, diaphragm. The lungs are the organs responsible for breathing, the alternate inhalation and exhalation of air.
The main air tube in your throat is called the trachea. You can feel its ridges of cartilage along the front of your neck. The trachea has two branches called bronchi which are also strengthened by cartilage. They lead to the lungs. The next smaller branches are called bronchioles; they are soft without cartilage since they are inside the lungs. The bronchioles lead to the alveoli where the work of the lungs takes place.
The tubes that air travels through to the lungs are the trachea, which leads to the bronchi (singular: bronchus), then to smaller bronchioles, and finally to the alveoli where gas exchange occurs in the lungs.
The two paths that lead to the throat are the trachea, which carries air to the lungs, and the esophagus, which carries food to the stomach.
The two main paths in the throat are the esophagus and the trachea. The esophagus leads to the stomach, allowing food to be transported for digestion, while the trachea leads to the lungs, allowing air to pass in and out for breathing.
Trachea, primary bronchi, secondary bronchi, tertiary bronchi, bronchioles, and alveoli!
No trachea is the medical name for the windpipe which leads down to the bronchi eventually to the blood through the lungs.
Windpipe is the common name for the trachea. These names represent the same structure.
Judicial Branch, Executive Branch, and Legislative Branch
They are called the tracheal rings. There are 16-20 of them.
