ANATOMY

Detailed explanation-1: -The trachea (windpipe) is the part of the airway that continues below the larynx (LAIR-inks). The walls of the trachea (TRAY-kee-uh) have stiff rings of cartilage to keep it open. The trachea is also lined with cilia, which sweep fluids and foreign particles out of the airway to keep them out of the lungs.

Detailed explanation-2: -When you inhale through your nose or mouth, air travels down your pharynx (back of your throat), passes through your larynx (voice box) and into your trachea (windpipe). Your trachea is divided into two air passages called bronchial tubes. One bronchial tube leads to your left lung, the other to your right lung.

Detailed explanation-3: -The trachea divides into the two main BRONCHI (tubes), one for each lung. The bronchi, in turn, subdivide further into bronchioles.

Detailed explanation-4: -The main function of the trachea is to transport air in and out of the lungs during the act of breathing. In addition, it protects the respiratory tract by warming and moistening the air and propelling foreign particles upwards towards the pharynx for expulsion.

Detailed explanation-5: -The trachea, commonly called the windpipe, is the main airway to the lungs. The trachea divides into the right and left primary bronchi, which branch into smaller and smaller passageways until they terminate in tiny air sacs called alveoli.
