Bronchus

One of two large passageways between trachea and the lungs.

One of the main branches of the trachea carrying air into the lungs.

One of the two air passages leading from the trachea into the lungs, where they split into many bronchioles.

Bronchi, one of the two large channels that lead from the trachea to smaller branches (bronchioles) and ultimately to the air sacs (alveoli) of the lung.

Section of the airway immediately posterior to the main trunk of the trachea that bifurcates into the right and left segments.

A tube that is an airway from the trachea (windpipe) into each lung. The main bronchus in the lung branches into smaller passages called segmental bronchi, which in turn branch further into smaller tubes called bronchioles.

Any of the air passages beyond the trachea (windpipe) that has cartilage and mucus glands in its wall. The trachea divides into two main bronchi, which divide successively into five lobar bronchi, 20 segmental bronchi, and two or three more divisions.

Bronchus, or bronchial tube, is the name applied to tubes into which the trachea divides, one going to either lung. The name is also applied to the divisions of these tubes distributed throughout the lungs, the smallest being called bronchioles.

One of the two large branches of the trachea. The trachea proper terminates at the level of the fourth thoracic vertebra. Each main (primary) bronchus enters the lung at its hilus. Inside the lung, the main bronchus branches into a bronchial tree (a set of smaller bronchi and bronchioles).

One of the two tubes that branch from the trachea and send air into each lung.

One of the two sizable conduits that establish a connection between the trachea and the lungs.

A bronchus refers to a significant air passage within the lung. Each lung possesses a main bronchus that originates at the terminus of the trachea, also known as the windpipe. This main bronchus subsequently branches into smaller segments referred to as segmental bronchi, which further divide into even smaller airways called bronchioles.
