yes the dermis contains both elastic and collagen fibers
Structural components of the dermis are collagen, elastic fibers, and extrafibrillar matrix.
Elastic fibers
dermis
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
The fibers found in the dermis are elastic fibers and collagen type I.
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.
is 1/5th of the thickness of dermis. Areolar Connective tissue which has elastic, collagen and reticular fibers. It is the region beneath dermal papillae ( finger-like projections in the uppermost part of the dermis just beneath the basement membrane of epidermis)
