bronchi
Alveoli
alveoli. they are the basic functional unit of the lungs. it is where gas exchange occurs.
Alveoli
Bronchioles. Air enters through the mouth, down the trachea and into the left and right main bronchi (which lead to the left and right lungs respectively) The bronchi then branch off continually into smaller and smaller bronchi. The very smallest of these are called bronchioles and they end in tiny air sacs called alveoli.
Almost right....the exchange takes place in the alveoli
The lungs contain alveoli, bronchioles, and bronchi. Alveoli are tiny air sacs where oxygen is exchanged for carbon dioxide in the blood. Bronchioles are small airways that branch from bronchi, which are larger airways that lead to the lungs.
The three main parts of the lungs are the bronchi (airways that carry air in and out of the lungs), the bronchioles (smaller airways that branch off from the bronchi), and the alveoli (tiny air sacs where gas exchange takes place).
The air sacs in the lungs where gases move into and out of the blood are called alveoli. They are tiny, thin-walled sacs surrounded by blood capillaries, allowing for efficient gas exchange between the lungs and the bloodstream.
The respiratory looks like an upside down tree, from the trunk to the branches and to fruit (such as an apple). From largest to smallest, the respiratory system consists of the throat to main bronchi, to bronchioles, to terminal bronchioles, to alveolar ducts, to alveolar sacs (aveoli look like tiny grapes).
The tiny air sacs of the lungs were oxygen and carbon dioxide are exchanged are the alveoli.
