the alvioli
The lungs are fed by one tube called the trachea (TRAY kee uh) This tube branches out into different levels of brachea (BRAY kee uh) which go to the two separate lungs.
It's called the "bronchial tree".
ok, think of your lungs as a cluster of grapes hanging upside down. The smallest branches are called bronchioles . At the end of each bronchiole is an "air sac" called alveoli .
alveoli
The smallest tube in the lungs is the Bronchus
The organ that branches off in front of the esophagus is the pharynx.
I believe the smallest are the alveoli (air sacs), since there are millions of them in the lungs.
The windpipe branches into two bronchi to direct air to and from both lungs (the left and right). The point where the windpipe branches is called the carina.
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.
You are correct.
Lungs have branching structures called bronchial tubes that resemble the branches of a tree. The bronchial tubes divide and become smaller, similar to how tree branches branch out into smaller twigs. This branching network in the lungs allows for efficient air distribution and gas exchange.
