Alveoli Meaning
The lungs‘ terminal bronchioles contain tiny, air-filled sacs called alveoli. Alveoli function as the place where gases are exchanged, enabling carbon dioxide to leave the body and oxygen to enter the circulation during breathing. For effective gas diffusion between the air inside the alveoli and the blood in the surrounding capillaries, specific cells lining the thin walls of the alveoli are present. Carbon dioxide, a waste product of cellular metabolism, is eliminated from the circulation and oxygen is supplied to the body’s cells through this process.

Diagram of Alveoli
The diagram of Alveoli shows it is composed of the lungs’ terminal bronchioles containing small, balloon-like structures called alveoli. Alveoli are found at the ends of bronchioles and the diagram of alveoli gas exchange shows them allowing carbon dioxide to be expelled from the body and oxygen entering the circulation. The diagram of alveoli in class 10 and class 11 is important for understanding the respiration chapter in the biology syllabus.
The labeled diagram of alveoli is given below:
