1. Trachea (mammal) – trachea is made up of 16-20 rings of cartilage. This is the body/s main type of connective tissue.
2. Pseudostratified Respiratory Epithelium – The bronchioles are lined by simple columnar to the cuboidal epithelium, and the alveoli possess a lining of thin squamous epithelium that allows for gas exchange.
3. Elastic Cartilage – the elastic cartilage provides support with moderate elasticity, and mainly found in the larynx. This also maintains the shape structures such as the external ear.
