What are the tubes at the lower end of the trachea?
The answer is: Bronchi
What are trachea and bronchi?
the trachea is air passage tube that allows air to enter your lungs. the bronchi are two little tubes that are connected to the end of your trachea and lead to the lungs.
The inferior end of the trachea divides into the left and right what?
The trachea branches into the left and right airways at the carina. These branched airways are called the bronchi.
What is the pathway of oxygen through your body?
The oxygen enters the body via the nose and mouth then travels down the trachea ( wind pipe ) then breaks into two bronchi (the bronchi splits the air into each lung) which then branches into lots of bronchioles which end in lots of alvioli.
Label the parts of bronchial tree?
respiratory zone is from respiratory bronchioles (generation 17-19) to alveolar ducts (generation 20-22) to alveolar sacs (generation 23). It is the site of gas exhange, where velocity of gas is low, and diffusion is the dominant mechanism of gas exchange.
What do air tubes do in the respiratory system?
Starting from the left and right bronchi, bronchus for singular, these branch down from the trachea. Then the bronchi branch off to smaller bronchi and these branch off to bronchioles. The bronchioles contain air sacs at the end called alveoli and alveolus for singular.
What is differences between trachea and bronchi?
The trachea, also known as the "windpipe," is the largest tube of the respiratory system. In the adult human it is approximately 5 inches long, and an inch in diameter. It technically begins at the inferior edge of the larynx (aka "voice-box") and continues down toward the lungs. At the inferior end of the trachea it bifurcates, or divides, into two slightly smaller tubes known as bronchi. The primary bronchi each divide into "secondary bronchi." On the right side, the primary bronchus (the term for a single bronchi), divides into a superior and an intermediate bronchus (secondary bronchi) before it enters into the right lung. On the left side, the primary bronchus enters the left lung, then divides into a superior and and inferior bronchus (secondary bronchi.)
What is located anterior to the esophagus and carries air to the bronchi?
The trachea splits into the left and right bronchi in the thoracic cavity(the chest). From there the bronchi continue to branch out and keep getting smaller. Kind of like the branches on a tree. At the end of the those branches (bronchioles) are the alveoli( tiny grape like structures). In the alveoli is where the exchange of oxygen and carbon dioxide occur.
What structure is located between the trachea and bronchiole?

Where is the Carina?
Runs anteroposteriorly between the two primary bronchi at the site of the tracheal bifurcation at the lower end of the trachea, usually at the level of the 4th to 5th thoracic vertebrae.
What tube brings air into and out of the body?
Bronchi---2 tubes that are off shoots of your trachea. Air travels through the nose and mouth to the trachea then to the bronchi. The left bronchi travels to the left lung and the right bronchi to the right lung. Each bronchi branches off into thousands of smaller branches called bronchioles (30,000 in each lung). At the end of each bronchiole is a special area that leads into clumps of teeny tiny air sacs called alveoli. There are about 600 million alveoli in your lungs.
