The elastic fibres recoil after the alveoli contract during expiration. The surfactant on the inner surface also helps to stop the alveolar walls 'sticking' together which will stop air from coming due to the pressure not being able to decrease

Elastic fibers in the connective tissue
If inhaled, asbestos in air can scar lung tissue.
The outer ear is primarily composed of elastic cartilage and fibrocartilage. Elastic cartilage forms the pinna of the ear, while fibrocartilage is found in the external auditory canal. These connective tissues provide structural support and flexibility to the outer ear.
Environmental factors like dirt can poorly affect the health of the lung tissues if inhaled. These particles will agitate the tissue.
Yes. The blood passes through the lung tissues and gets oxygen.
Because the stomach needs the muscle tissue and the elastic tissue to stretch and digest the food.
When normally elastic connective tissues are replaced with nonelastic fibrous tissues, this can result in decreased flexibility and increased stiffness in the affected area. This transformation can lead to conditions like fibrosis or scar tissue formation, which may impair the function and movement of the tissues or organs involved.
Upper layer of arteries is made up connective tissues,middle layer of elastic tissues and inner layer of endothelium vein have the same composition but it is relatively less elastic then the arteries.
Lung cancer primarily arises from the epithelial tissues of the lungs, specifically the bronchial epithelium, which lines the airways. The two main types of lung cancer are non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC), each originating from different types of epithelial cells. Additionally, the tumor microenvironment, which includes connective tissues, immune cells, and blood vessels, also plays a crucial role in the development and progression of lung cancer.
