Inside the chest each bronchus divides into smaller and smaller passageways known as?
The bronchial 'tree':The pharynx is the trunk. The primary bronchi are the first two large branches. They branch to form tertiary bronchi.Each tertiary bronchus branches into multiple bronchioles, which branch further into the very smallest conducting branches, the terminal bronchioles.The terminal bronchiole branches to form several respiratory bronchioles, where gas exchange takes place.
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.
Which parts of the respiratory system divide into smaller and smaller tubes in a pattern that resembles the branches of a tree?
it divides into two bronchis and the the aveioli
What tube in the lungs connects the windpipe to the air sacs?
The bronchi. There is a left and right main bronchus dividing off the windpipe (trachea), each bronchus undergoes several divisions (about 16-17) becoming smaller and thinner before ending on the air sacs (alveoli), which provide the interface between the airways and the blood vessels so that gas exchange can take place.
Is oral cavity part of respiratory system?
No, they are not part of the respiratory system. They are analogous to bones and participate in the digestive system by breaking down food into smaller particles.

How does the bronchi work?
A bronchus is a passage of airway in the respiratory tract that conducts air into the lungs. The bronchus branches into smaller tubes, which in turn become bronchioles.
Which parts of the respiratory system divide into smaller and smaller tubes?
The bronchi are passages that direct air into the lungs, which are the main organs of the respiratory system. Inside of the lungs, each bronchus divides into smaller and smaller tubes, resembling the branches of a tree. At the end of the tubes are the alveoli, which are the tiny sacs of lung tissue specialized for the movement of gases between air and blood.
Comparing with the right main bronchus the left main bronchus?
The right main bronchus is wider, shorter, and more vertical than the left. The left main bronchus is smaller in caliber,but 5 cm longer than the left bronchus.
Is it true that inside the lungs each bronchus divides into smaller and smaller tubes?
true
What is the difference between trachea and bronchi?
Bronchi (plural of bronchus) are tubes that branch off from the trachea into each lung. Bronchioles are smaller tubes that branch off from each bronchus. Also there are only two bronchi compared with the hundreds of bronchioles
What are the main structures of the respiratory systems?
The main structures of the respiratory system are:mouthnosepharynx (throat)larynx (vocal cords)trachea (windpipe)bronchi (singular is bronchus; these are the two smaller tubes that are branches of the trachea)bronchioles (even smaller tubes off of the bronchi)lungsalveoli (singular is alveolus; these are tiny sacs on the bronchioles that are surrounded by blood vessels that allow oxygen into the blood)
What are the structures of the lungs?
the trachea also known as the wind wipe joins to the two bronchus which enter each lung. The bronchus gets gradually smaller until they become the bronchioles, these then terminate at the alveoli.
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.
Is bronchus plural?
No. The plural is bronchi. The bronchi are the largest of the passages leading into the lungs. The smaller ones are bronchioles.
Is the following sentence true or false I need to know before tomorrow Inside the lungs each bronchus divides into smaller and smaller tubes?
true
What is respiratory system is made up of?
The nose ----> meatuses--->the pharynx (throat)----->oropharynx ---> laryngopharynx passes food to the esophagus and air to the larynx.----->trachea (windpipe)---->The primary bronchi branch from the trachea to the left and right lungs---->each primary bronchus divides repeatedly into branches of smaller diameters, forming secondary (lobar) bronchi, tertiary (segmental) bronchi, and numerous orders of bronchioles (1 mm or less in diameter), including terminal bronchioles (0.5 mm in diameter) and microscopic respiratory bronchioles----->alveolar ducts are the final branches -----> alveolar duct ----> alveolus ---->the respiratory membrane (the alveolar and capillary walls) is where exchange of gases occur.
