Growth of the alveoli and pulmonary arteries in childhood

Growth of the alveoli and pulmonary arteries in childhood alveoli The pulmonary alveolus is known as a pump for breathing Alveoli cells are tiny, grape-shaped, distensible sacs They allow alveoli The terminal bronchioles then subdivide into respiratory bronchioles which subdivide into alveolar ducts Numerous alveoli and alveolar sacs

alveoli Bronchioles and alveoli in the lungs In your lungs, the main airways, called bronchi, branch off into smaller and smaller passageways The smallest airways,

alveoli The alveoli form clusters, called alveolar sacs, that resemble bunches of grapes By the same analogy, the alveolar ducts leading to the sacs are like the stems This may cause excessive mechanical forces in aerated lung regions, between aerated and nonaerated lung regions, or in bronchioles and alveoli that open and
