Lungs are made of spongey elastic tissue. Muscles around the lungs help it contract.

The type of tissue in the lungs is mostly epithelial. The other tissue is connective, and some of this is blood, which is a liquid connective tissue.
It actually contains smooth muscle tissue, and alveolar connective tissue. This connective tissue contains collagen fibers for flexibility and strength, and numerous elastic fibers that enable it to be stretched. Alveolar connective tissue is found in the skin and in most internal organs of vertebrates, where it allows the organs to expand, which is essential for the lungs.
1. Muscle 2. connective tissues expand and contract the lungs. 3. Nervous tissue sends and receives messages that help regulate gas exchange in the lungs and the rate at which a person breathes. 4. Epithelial tissue forms the inner lining of the lungs.
The lungs tissues are made up mainly of squamous epithelial tissue (called alveolar epithelium in the lungs). This type of tissue serves a critical function within the lungs because it allows the transfer and exchange of gases with little or no resistance. The advantages are a short distance between the Oxygen in the alveoli and the blood in the capillaries.The lungs also contain ciliated epithelium. A function of ciliated epithelium is stimulation of goblet cells to produce a mucous-like substance that not only lubricates but also traps pathogens and particles in the bronchi.
Epithelial tissue lines the outer surface of the body and lines the hollow organs.
Trachea, bronchi, nasopharynx and male urethra
== Epithelial tissue is located on the very outside of an organ or organism (i.e. skin) or found lining lumen (cavities in hollow organs (i.e. stomach lining). Epithelial tissue always has a free surface (no contact with another cell). Epithelial tissue is also avascular (no blood vessels) and must depend on underlying tissues for the nutrients and oxygen it needs to maintain homeostasis. For this reason, epithelial tissue is usually very thin. Another characteristic of epithelial tissue is that it has little to no intercellular matrix between it's cells. The cells are tightly packed together. Major functions of epithelial tissue include, protection, secretion, and absorption. And as another wiki person ID1342641670 said The epithelial tissue protects the main organ (the heart) from rubbing and damaging the lobes in the heart against the lungs it provides an extra barrier for security and saves the heart from injuries to the upper body around the heart area===
elastic connective tissue is found in the lungs. The tissue is able to extend when forces are applied to stretch it, yet returned undamaged to its previous condition when the force is released.
To allow passage of materials by diffusion and filtration in sites where protection is not important; secretes lubricating substances in serosae.
