The pleura is a thin tissue layer that covers the lungs. Pleura is the same type of thin tissue that lines the inside of the chest cavity. With each breath, a small coating of fluid works as a lubricant, helping the lungs to expand and collapse easily.
The bronchi are a combination of cartilage and tissue. Each inhale and exhale passes through the cartilage, which keeps the bronchi robust and open. The ratio of cartilage to smooth muscle reduces as the airways become smaller.
The trachea is made up of roughly 20 strong cartilage rings. Each ring’s back is made up of muscle and connective tissue. The mucosa is a moist, silky tissue that lines the inside of the trachea. With each breath in, the trachea widens and lengthens slightly before returning to its resting state.
