Elastic fibers
dermis
The dermis contains mainly collagen fibers, which provide strength and support to the skin. Additionally, there are elastic fibers that allow the skin to stretch and recoil. Finally, reticular fibers can also be found in the dermis, providing a supportive framework for the skin cells.
a decrease in the elastic fiber network of the dermis
The dermis contains dense irregular connective tissue with elastic fibers and collagen type I. It also contains very few fibroblast cells.
The reticular layer of the dermis
Collagen fibers makes up 75% of the dermis, which is the inner layer of skin that protects the body from physical stress, it also contains elastic fibers, and ground substances.
Lungs are made up of millions of alveoli and bronchial tubes.
The fibers found in the dermis are elastic fibers and collagen type I.
