In the event that lung cancer restricts airflow to a particular group of alveoli, the affected alveoli's volume would grow, and its arterioles would vasodilate.
While breathing in and out, both carbon dioxide and oxygen are exchanged between the blood and alveoli in the lungs. When oxygen is inhaled from the air, it gets to the body's tissues via the alveoli, blood, and structures inside the body.
Capillary cells, alveolar epithelium type 1 cells, and epithelial cell type 2 cells make up the alveolus. Large, smooth epithelial cells known as type 1 cells occupy around 95% of alveolar surface area. Type 2 cells function and generate surfactant.
