When you breathe:
- Air passes from your mouth to your trachea.
- Your trachea divides into your left and right bronchi.
- The bronchi carry air into your lungs.
- At the end of the bronchi, the bronchioles carry air to small sacs in your lungs called alveoli. The alveoli perform your body’s gas exchange.
What are the two tubes that carry air from the trachea?
The two tubes that carry air from the trachea to the lungs are called bronchial tubesThe bronchial tubes. As these tubes pass through the lungs, they divide into smaller passages called the bronchioles. The bronchioles end in air sacs called alveoli. What are two tubes that branch off of the trachea and carry air into the lungs? ask your mom
What are the two tubes that enter the lungs?
At its bottom end, the trachea divides into left and right air tubes called bronchi (BRAHN-kye), which connect to the lungs. What are the large tubes that enter the lungs?
How many bronchi are there in the trachea?
Explanation: The trachea or windpipe divides into the two primary bronchi which enter each lung. These further divide and subdivide into smaller and smaller bronchi finally forming tiny tubes called bronchioles that end in alveloi (air sacs that facilitate oxygen transfer from the lungs into the pulmonary capillaries).
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 two tubes of the trachea?
Further down, the trachea divides into two tubes (left and right) called bronchi (BRAHN-kye). The bronchi connect the trachea to the lungs.
What are the two main airways connecting the trachea to the lungs?
The trachea branches into two smaller airways: the left and right bronchi, which lead to the two lungs.
What is the tube that connects the throat and the bronchial tubes?
The TRACHEA (windpipe) is the passage leading from your pharynx to the lungs. The RIBS are bones supporting and protecting your chest cavity. They move a small amount and help the lungs to expand and contract. The trachea divides into the two main BRONCHI (tubes), one for each lung.
What are 2 systems connected to the respiratory system?
Your respiratory system relies on your circulatory system to deliver the oxygen it gathers, while the muscles of your heart cannot function without the oxygen they receive from your lungs.
What are the two parts of the airway?
The respiratory tract is divided into two main parts: the upper respiratory tract, consisting of the nose, nasal cavity and the pharynx; and the lower respiratory tract, consisting of the larynx, trachea, bronchi and the lungs.
What are those two tubes in your throat used for?
Auditory (eustachian) tubes: These two tubes connect the ears to the throat. They equalize pressure and help drain fluid.
What connects the throat and the trachea?
The larynx, commonly called the voice box or glottis, is the passageway for air between the pharynx above and the trachea below.
Why are there two bronchial tubes?
The left bronchus carries air to your left lung. The right bronchus carries air to your right lung. Your bronchi are an essential part of your respiratory system. As you breathe and your lungs expand, your bronchi distribute the air within your lung.
What is the main airway to the lungs?
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.
What connects upper and lower airway?
The larynx connects the lower part of the pharynx, the laryngopharynx, to the trachea. It keeps the air passages open during breathing and digestion and is the key organ for producing sound. This larynx is comprised of nine cartilages.
Where does the trachea split into two passages?
In the mediastinum, at the level of the fifth thoracic vertebra, the trachea divides into the right and left primary bronchi. The bronchi branch into smaller and smaller passageways until they terminate in tiny air sacs called alveoli.
What is the main passageway that leads to the lungs from the throat?
The larynx is the upper opening into the windpipe (trachea), the passageway to the lungs. Epiglottis — a flap of soft tissue and cartilage located just above the vocal cords. The epiglottis folds down over the vocal cords to help prevent food and irritants from entering the lungs.
What is the trachea?
Trachea. The trachea, also called the windpipe, is part of the passageway that supplies air to the lungs. Any prolonged blockage, even for a few minutes, can cause death. The trachea is about 4.5 inches long and 1 inch in diameter, and is comprised of smooth muscle and several c-shaped rings of cartilage.
What is the bronchial tree?
Bronchial tree. 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.
How many bronchioles are there in the lungs?
The secondary bronchi continue to branch off to form the tertiary bronchi, which are further divided into terminal bronchioles. There are as many as 30,000 tiny bronchioles in each lung. They lead to the alveoli by way of alveolar ducts.
How much mucus is in the air?
The mucus is an important air purifier. The average adult produces about 125 milliliters of mucus daily, which is slightly more than half a cup. Microscopic, hair-like cilia move the cleansing mucus up to the pharynx—part of the throat between the mouth and esophagus—from the lower part of the bronchial tree.
What is the function of the alveoli?
The alveoli are responsible for the primary function of the lungs, which is exchanging carbon dioxide and oxygen. A layer of protective mucus, called a mucus blanket, covers a large portion of the membrane lining the bronchial tree. The mucus is an important air purifier.
Where are the bronchi located?
Bronchi. Structurally similar to the trachea, the two primary bronchi are located inside the lungs. The right bronchus is slightly larger than the left one. Because of this, foreign objects breathed into the lungs often end up in the right bronchus.
