PPT-Histological features of trachea and primary bronchus:

Mucosa Sub mucosa Adventitia Mucosa is composed of respiratory epithelium and lamina propria as layer of loose connective tissue elastic and few reticular fiber lymphatic tissue is found with serous and mucous glands. Trachea, Bronchial Tree, Lungs. Trachea. Extends from larynx into the thoracic cavity where it splits into the left and right bronchial tree. Trachea. Structure. Lined with ciliated mucous membrane. Membrane filters out particles and moves them up to the pharynx where they can be swallowed. Beneath the submucosa: . 16-20 C-shaped hyaline cartilages. that keep the lumen permanently open. Cartilages form an incomplete ring around the trachea. Open on the posterior aspect where a thick layer of smooth muscle fibers (. Tracheo. -Bronchial Tree. Dr. Supreet Singh .
