The alveoli, from the Latin alveolus, "little cavity" are an anatomical structure that have the form of hollow cavities. Found in the lung, the pulmonary alveoli are spherical outcroppings of the respiratory bronchioles and are the primary sites of gas exchange with the blood. Alveoli are only found in the lungs of mammals.
What else can I help you with?
Where is the aveoli located?
The alveoli are small air sacs located at the end of the bronchioles in the lungs. They are responsible for gas exchange, where oxygen from the air is absorbed into the bloodstream and carbon dioxide is released from the bloodstream into the lungs to be exhaled.
What do the bronchioles connect?
The Bronchioles connect the brochi and the alveoli
What are the walls of the bronchioles made up of?
The walls of the bronchioles are made up of smooth muscle, connective tissue, and epithelial cells.
Is the bronchiole surrounded by blood capillaries?
No, bronchioles are part of the respiratory system and are not surrounded by blood capillaries. Bronchioles are airways within the lungs that help transport air to the alveoli for gas exchange. Blood capillaries are located near the alveoli for the exchange of oxygen and carbon dioxide.
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.
Is the alveoli located at end of bronchi?
They're located at the end of the bronchioles which are connected to the bronchi
What is the endpoint of bronchioles?
Respiratory bronchioles end in alveolar sacs (alveoli).
What structure is at the end of the smallest tubes in lungs?

How does oxygen get into the lungs?

Where are the cilia in the respiratory system located?
In the lining of the trachea, bronchi, and bronchioles.
Where is the aveoli located?
The alveoli are small air sacs located at the end of the bronchioles in the lungs. They are responsible for gas exchange, where oxygen from the air is absorbed into the bloodstream and carbon dioxide is released from the bloodstream into the lungs to be exhaled.
What is the more common name for the alveoli?
The Air Sacs or The End of the Bronchioles.
