The secondary bronchi go into the LOBES of the right and left lung. There are 3 lobes in the right lung and 2 lobes in the left lung, both having lobar bronchi.
There are five (5) secondary bronchi (aka lobar bronchi). Three (3) on the right: 1) superior lobar bronchi 2) middle lobar bronchi 3) inferior lobar bronchi And two (2) on the left: 4) superior lobar bronchi 5) inferior lobar bronchi
The human respiratory system typically has two primary bronchi, one for each lung. These primary bronchi then branch into secondary (lobar) bronchi, with three in the right lung and two in the left lung, totaling five secondary bronchi. Each secondary bronchus further divides into tertiary (segmental) bronchi, resulting in a complex network of bronchi throughout the lungs. In total, there are over 20 tertiary bronchi in each lung, leading to a large number of smaller bronchi and bronchioles.
The bronchial tubes, or bronchi, begin at the trachea (windpipe) where it bifurcates into the left and right main bronchi at the level of the fifth thoracic vertebra (T5). These main bronchi then branch into smaller secondary (lobar) bronchi and further into tertiary (segmental) bronchi within the lungs, facilitating airflow to each lung lobe and segment.
Bronchus (Greek for "windpipe") is singular. Bronchi is plural. The primary right and left bronchi direct the air into the right and left lungs. It then splits to go to each lobe of the lung. These tubes are secondary or lobar bronchi. The next division is the bronchiole tree, the alveolar duct and the alveolar sacs or clusters. Another less common name for the bronchi is "Respiratory Ducts".
The smallest is a segmental bronchus. The trachea is the largest and branches into the main (left and right) bronchi which then branch several times before branching into lobar bronchi and then segmental bronchi. Each lung is made up of lobes (generally the left lung has 2 lobes and the right has 3) and the lobes are comprised of segments.
Trachea branches to the mainstem bronchus branches to the lobar bronchi branches to the segmental bronchi to the bronchioles branches to the terminal bronchioles branches to the respiratory bronchioles branches to the the alveolar ducts finally lead to the alveoli.Or... Trachea to Bronchus (Bronchi) to the bronchioles to the alveolar ducts to the alveoli.
It refers to the branch from the bronchi that enters one lobe of one of the lungs
The bronchial tree divides into a series of branching airways that begin with the trachea, which bifurcates into the left and right primary bronchi. Each primary bronchus then divides into secondary (lobar) bronchi, which correspond to the lobes of the lungs—three on the right and two on the left. These secondary bronchi further branch into tertiary (segmental) bronchi, and this division continues into smaller bronchi and bronchioles, eventually leading to the alveoli where gas exchange occurs. This hierarchical structure allows for efficient airflow and distribution of air throughout the lungs.

It refers to the branch from the bronchi that enters one lobe of one of the lungs
"Lobar bronchus" literally means a bronchus that supplies a lobe of the lung. It is a branch of the main bronchus that further divides into smaller bronchi to provide air to specific lung lobes.
The trachea is the big straight tube that brings air to the lungs. The trachea then divides into main stem bronchi, lobar bronchi, segmental bronchi, bronchioles, etc.
