Where does the bronchial tubes branch off into?
lungs
When a person breathes, air taken in through the nose or mouth then goes into the trachea (windpipe). From there, it passes through the bronchial tubes, into the lungs, and finally back out again. The bronchial tubes, which branch into smaller tubes called bronchioles, are sometimes referred to as bronchi or airways.
What part of the respiratory system resembles upside down?
The bronchi themselves branch many times into smaller airways, ending in the narrowest airways (bronchioles), which are as small as one half of a millimeter (or 2/100 of an inch) across. The airways resemble an upside-down tree, which is why this part of the respiratory system is often called the bronchial tree.
What are the two branches in the lungs that branch off of the trachea?
At its bottom end, the trachea divides into left and right air tubes called bronchi (BRAHN-kye), which connect to the lungs. Within the lungs, the bronchi branch into smaller bronchi and even smaller tubes called bronchioles (BRAHN-kee-olz).
What is the first tube to branch off of the trachea?
Exam 3: Chapter 14: Respiratory System Review
| A | B |
|---|---|
| glottis | space between the vocal cords, opens into trachea |
| primary bronchi | The first branch off the trachea in the lung |
| tidal volume | amount of air exchanged during a normal breath |
| inspiratory reserve volume | amount of air that can be forcibly inspired after normal breath |
Does the trachea branch into the bronchial tubes?
The trachea, or windpipe, is the continuation of the airway below the larynx. At its bottom end, the trachea divides into left and right air tubes called bronchi (BRAHN-kye), which connect to the lungs. Within the lungs, the bronchi branch into smaller bronchi and even smaller tubes called bronchioles (BRAHN-kee-olz).

Why are our lungs designed like a branching upside-down tree?
Think of your respiratory system as an upside-down tree. When air enters your body, it goes down your trachea. Then, like tree branches, those airways break off into four, then eight, then hundreds of thousands of little airways in each lung. Those are your bronchi.
What are bronchial tubes?
When a person breathes, air comes in through the nose or mouth and then goes into the trachea (windpipe). From there, it passes through the bronchial tubes, which are in the lungs. These tubes let air in and out of your lungs, so you can breathe. The bronchial tubes are sometimes referred to as bronchi or airways.
Are the two branching tubes that connect the trachea to the lungs?
The bronchi are the two large tubes that carry air from your windpipe to your lungs. You have a left and right main bronchus in each lung. After the main bronchi, these tubes branch out into segments that look like tree branches.
What tube connects to the bronchial tubes?
The trachea is the tube that connects the mouth and nose to your lungs. It is also called the windpipe.
What are your bronchial tubes?
What is a bronchial tube?

Is the bronchial tree the same as the trachea?
Together, the trachea and the two primary bronchi are referred to as the bronchial tree. At the end of the bronchial tree lie the alveolar ducts, the alveolar sacs, and the alveoli. The tubes that make up the bronchial tree perform the same function as the trachea: they distribute air to the lungs.
What are the effects of tumors in the trachea and bronchi?
Tumors in the trachea and bronchi can block the airway and cause breathing problems. Most of the tumors that form in the trachea and bronchi in adults are cancerous, but a few are noncancerous.
What is the right bronchi?
Your bronchi split out from the trachea behind your sternum, or breastbone – that necktie-shaped hard piece of bone just under your throat that holds onto most of your ribs and helps protect your critical organs. They are called the right or left bronchus, depending on which lung they serve.
