This connective tissue type contains elastic fibers and is found in the lungs. this tissue allows the lungs to inflate during inhalation and return to their original shape after exhaling.

Lungs are the primary organs of the breathing involved in the process of inhalation and exhalation. Both of these processes require a flexible tissue due to the structural changes during it. This connective tissue of the lungs is called the elastic connective tissue.

Elastic fibres refers to the bundle of protein called the elastin found in the extracellular matrix of the connective tissue proper. They are found in the lungs and its characteristic feature is it can stretch and compress back to its original shape allowing the processes of inhalation and exhalation. It is also called the yellow elastic tissue.
