It travels down the trachea – or windpipe – into one of two bronchi and into bronchioles before entering one of millions of alveoli, where gaseous exchange takes place. When we breathe out ...

Oxygen gets into the blood through tiny blood vessels around the alveoli. Red blood cells pick up the oxygen and deliver it to the body's cells. When you breathe out, the same thing happens – only in ...

Here, it continues distally to the carina, then through the primary bronchi, various branches of bronchioles, and eventually arriving in the alveoli. This is inhalation. Air movement in a reverse ...

Airway clearance techniques (ACTs) help clear the mucus from these segments. Each segment has airways (bronchi), air sacs (alveoli), and blood vessels (arteries, veins, and capillaries). Oxygen and ...

the present study establishes the growth pattern of the arteries and relates this to that of the alveoli and airways. The pattern of post-natal alveolar multiplication found is similar to that ...
