Air enters the body through the nostrils or the mouth, passing down the throat to the larynx, and then to the trachea. The trachea divides into two branches in the chest cavity, the right and left bronchi that enter the lungs. The branches of the bronchi narrow down to tubes called bronchioles of less than 1 mm diameter, and these sub-divide into even narrower tubes called alveolar ducts. Each alveolar duct ends in a grapelike cluster of thin-walled sacs, called alveoli. From 300 million to 400 million alveoli are contained in each lung.
What else can I help you with?
Describe the structure of a terminal bronchiole and its alveolar sac?
terminal brobchiole is formed as a result of division of respiratory bronchiole. It is extremely thin and end up into alveolar sac ALVEOLAR SAC THESE ARE SMALL SACS WITH 8 TO 10 SACCULES CALLES ALVEOLI. IT HAS CENTRAL AIR PASSAGE. THESE ALVEOLI SERVE AS RESPIRATORY MEMBRANE AND HELP IN EXCHANGE OF GASES
What is abronchiole?
It seems like there may have been a typo. The correct term is "bronchiole." Bronchioles are small airways in the lungs that branch off from the bronchi and help carry air to the alveoli for gas exchange. They are essential for delivering oxygen to the body and removing carbon dioxide.
Where in the lung does exchange of O2 and CO2 take place?
Gas exchange between oxygen and carbon dioxide takes place in small sacs called alveoli, which are located at the end of the respiratory bronchioles in the lungs. This is where oxygen from the air is transferred into the bloodstream and carbon dioxide is removed from the blood.
Oxygen and carbon dioxide pass back and forth between the alveoli and the blood through?
The process of simple diffusion. Oxygen moves from the alveoli into the blood where it binds to hemoglobin in red blood cells, while carbon dioxide moves from the blood into the alveoli to be exhaled out of the body.
Is blood transported through the alveolis?
No, blood is not transported through the alveoli. The alveoli are tiny air sacs in the lungs where gas exchange occurs between the lungs and the blood vessels. Oxygen is taken in from the air and carbon dioxide is removed from the blood in the alveoli.
What is at tip of each bronchiole?
Alveoli.
Which structure branches further into alveoli?
the bronchiole
The innermost chamber of respiratory system into which air can be drawn is ..........?
innermost chamber of respiratory system into which air can be drawn is . Bronchiole
Are your left and right lungs exactly the same?
Bronchiole tubes, bronchioles, and alveoli.
Where does the oxygens exchange take place?
It happens in the Alveoli. The Alveoli is a balloonlike air sacs that is found at the end of each end of bronchiole.
What are the small chambers of the lungs that are involved in the exchange of gases?
The alveoli are small sacs within the lungs where gas exchange occurs. They are located at the ends of bronchiole branches.
What are the names of the tiny air sacs at the end of the bronchioles?
identify the part of the resperatory system which cluster of tiny thin walled sacs found at the end of leach bronchi
When the bronchiole constricts which will happen to resistance?
decrease in oxygen provided to the alveoli
What is the main difference between a bronchus and a bronchiole?
A bronchiole has no cartilage in its wall, a bronchus does.
Branches of the windpide that lead into the lungs are the?
trachea- primary bronchi- secondary bronchi- tertiary bronchi- bronchiole- alveoli
What is a bronchi Ole?
Bronchiole tube is a narrow tube formed by repeated branching of the bronchi, which conducts air into the alveoli.
What is a bronchi ole tube?
Bronchiole tube is a narrow tube formed by repeated branching of the bronchi, which conducts air into the alveoli.
