Diseases that can affect these airways include: Your airways branch into tiny tubes (bronchioles) that end in clusters of air sacs called alveoli. These air sacs make up most of your lung tissue.

The trachea is part of the lower respiratory tract, along with the lungs, bronchi, bronchioles, and alveoli. The strong, flexible tube is also called the windpipe because its main job is to move air ...

Alveoli are tiny air sacs in your lungs that take up the oxygen you breathe in and keep your body going. Although they’re microscopic, alveoli are the workhorses of your respiratory system.

Pictured: heart, lungs, alveoli, capillaries, bronchi, pulmonary veins, and pulmonary arteries. The lungs contain thousands of thin tubes that end in bunches of tiny, balloon-shaped air sacs ...

When we breathe in, air flows into our lungs and into the air sacs. Alveoli increase in size by changing their shape and unfolding. In a gas exchange, oxygen from the respiratory air enters the ...

together they filter the air of things like dust before it enters the lungs. The two bronchi, branch off into smaller bronchioles, which almost resemble a tree-like structure. At the ends of the ...

6, 2022 – Alveoli are the basic functional units of the human respiratory system, acting as tiny air sacs that exchange gases. Air inhaled through the mouth and nose flows into the lungs through ...
