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.
Do the airways opening along the tertiary bronchus contain cartilage?
No, the airways opening along the tertiary bronchus do not contain cartilage. The tertiary bronchus branches into smaller bronchi, called bronchioles, which are lined with smooth muscle instead of cartilage. This allows for increased flexibility and control over airway diameter.
What does lobar bronchus mean literaly?
"Lobar bronchus" literally means a bronchus that supplies a lobe of the lung. It is a branch of the main bronchus that further divides into smaller bronchi to provide air to specific lung lobes.
Would the biomass of a tertiary consumer be larger or smaller than the biomass of a primary consumer?
The biomass of a tertiary consumer would be smaller than the biomass of a primary consumer. This is because energy is lost as it moves up the food chain through each trophic level. Tertiary consumers have less available energy and biomass compared to primary consumers.
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.

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.
What does lobar bronchus mean literaly?
"Lobar bronchus" literally means a bronchus that supplies a lobe of the lung. It is a branch of the main bronchus that further divides into smaller bronchi to provide air to specific lung lobes.
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
How many bronchi are there in air passage way?
The human respiratory system typically has two primary bronchi, one for each lung. These primary bronchi then branch into secondary (lobar) bronchi, with three in the right lung and two in the left lung, totaling five secondary bronchi. Each secondary bronchus further divides into tertiary (segmental) bronchi, resulting in a complex network of bronchi throughout the lungs. In total, there are over 20 tertiary bronchi in each lung, leading to a large number of smaller bronchi and bronchioles.
What is the function of the right main bronchus in the respiratory system?
The right main bronchus is a vital airway in the respiratory system that branches off from the trachea to supply air to the right lung. It is wider and more vertically oriented than the left bronchus, making it more likely for aspirated objects to enter. Its primary function is to facilitate the passage of oxygen-rich air into the right lung for gas exchange. Additionally, it helps in filtering, warming, and humidifying the air before it reaches the lung tissue.
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 branches of the trechea?
The trachea branches into the left and right main bronchi, which further divide into smaller bronchi within the lungs. These smaller bronchi continue to branch into bronchioles, which eventually lead to alveoli where gas exchange occurs.
