Air enters the lungs through several tubes, starting with the trachea, which branches into the left and right bronchi. These bronchi further divide into smaller bronchioles, leading to tiny air sacs called alveoli where gas exchange occurs. The entire pathway ensures that air is efficiently delivered to the lungs for oxygen absorption and carbon dioxide removal.
What else can I help you with?
Which is the pathway of oxygen to the lungs?
Oxygen enters the body through the mouth or nose, passes through the trachea (windpipe), then enters the bronchial tubes in the lungs. Within the lungs, the oxygen is absorbed by tiny air sacs called alveoli and then enters the bloodstream to be transported to cells throughout the body.
Do dragonflies breath trough there lungs?
No, dragonflies do not breathe through lungs like mammals do. Instead, they have a system of tubes called tracheae that deliver oxygen directly to their tissues. Air enters their bodies through small openings in their exoskeleton, called spiracles, and is transported through these tubes. This allows them to efficiently exchange gases while remaining lightweight and agile in flight.
How is oxygen taken in by lungs?
Oxygen is taken in by the lungs through the process of inhalation. When you breathe in, air containing oxygen enters the lungs through the trachea and bronchial tubes, eventually reaching the alveoli where oxygen is absorbed into the bloodstream.
The branching tubes within the lungs end at small?
The branching tubes within the lungs end at small alveoli.
Do bumblebees have lungs?
No, bumblebees [Bombus spp] don't have lungs. Instead, they breathe through a system of air tubes, sacs and holes. The holes are called 'spiracles'. The tubes are called 'trachea'. The air enters the body through the spiracles, is distributed by the trachea and is stored in the sacs.
What are Small openings on the side of the body through which air enters and leaves tracheal tubes?
Spiracles
What 2 tubes connect to the lungs?
The bronchial tubes connect the trachea and the lungs. Air moves through these tubes into and out of the lungs.
In mammals air enters lungs through tubes called which branch into smaller tubules called which extend out to tiny air sacs called?
In mammals, air enters the lungs through tubes called bronchi, which branch into smaller tubules called bronchioles. These bronchioles extend out to tiny air sacs called alveoli, where gas exchange occurs.
What small tubes within your lungs?

How does oxygen travel through the lungs?
Oxygen enters the body through inhalation, where it passes through the nasal passages or mouth into the trachea. It then travels down the bronchial tubes, reaching the alveoli in the lungs where it diffuses into the bloodstream through tiny blood vessels called capillaries.
What are the lots of small tubes inside are lungs?
Brachea
What are the tiniest tubes in the lung called?
They are called the bronchiThe smallest [air] tubes in the lungs are the broncioles they terminate the larger bronchi.Inside your lungs the two bronchi tubes divide into small bronchial tubes. The bronchial tubes then divide into bronchioles, which are even smaller air passages. Tiny air sacs, called alveoli, are on the ends of the bronchioles.The small tubes located within the lungs are known as the bronchial tubes. The bronchial tubes function is to purify the air that is going into the lungs, when the bronchial tubes become inflamed and swell, Asthma attacks can occur.
