What Are Some Types of Respiratory System Tissue?

The respiratory system includes several types of tissue, including bronchi and bronchioles, as well as lung interior, pleural membrane and alveoli, according to InnerBody. The epiglottis is a thin piece of tissue covering the wind pipe, reports the National Heart, Lung, and Blood Institute.

Smooth muscle tissue in the bronchi and bronchioles carry air into the lungs from the trachea, states InnerBody. Alveoli are tiny sacs lining the inside of the lungs, surrounded by spongy tissue and capillaries. Alveoli are lined with a tissue that allows an exchange of air with gases in the blood passing through capillaries.The pleural membrane surrounds the lungs, giving them space to expand and pressure to empty.
