Histology Of Respiratory System
Histology of respiratory system. The respiratory system subdivides into a conducting portion. The epithelium is tall columnar pseudostratified with cilia and goblet cells. The respiratory mucosa is made up of the epithelium and supporting lamina propria.
This chapter will cover the respiratory system. Start studying Histology of respiratory system. 8 minutes The respiratory tract is the pathway through which much needed oxygen enters the body.

The respiratory system is constantly filtering through the external environment as humans breathe air. The respiratory system consists of two divisions with distinct structural elements that reflect their unique functions. This portion is composed of the nose pharynx larynx trachea bronchi and bronchioles.
The respiratory system consists of the upper respiratory tract nasal passages the airway conduction system larynx trachea bronchi bronchioles and terminal bronchioles and the lower respiratory tract alveolar ducts and alveoli. 25-2 Organization and Functions of the Respiratory System Structural classifications. Upper respiratory tract lower respiratory tract.
Nose nasal cavity Pharynx Larynx Trachea progressively smaller airways from the primary bronchi to the bronchioles. This process involves inhaling air and conducting it to the lungs where gas exchange occurs in which oxygen is extracted from the air and carbon dioxide expelled from the body. The respiratory portion begins at the level where alveoli first appear in the final branches of the bronchioles.
The respiratory system also called the pulmonary system consists of several organs that function as a whole to oxygenate the body through the process of respiration breathing. Mesodermgives rise to the connective tissue cartilage and smooth muscle of the respiratory tract.
Food moves along the digestive system from the mouth where it is ingested to the anus where the undigested and unabsorbed remnants of food and some additional waste are eliminated.
Bronchi - histology Diameter decreases Epithelium similar to trachea Shape and arrangement of the cartilage and smooth muscle are different With decrease of DM Cartilage ring become irregular isolated plates Smooth muscles in the LP are spirally arranged Lymphocytes lymphoid aggregations in the LP. The supporting lamina propria underneath the epithelium contains elastin that plays a role in the elastic recoil of the trachea during inspiration and expiration together with blood vessels that warm the air.

Respiratory mucosa which includes epithelium and supporting lamina propria submucosa cartilage andor muscular layer. The epithelium is tall columnar pseudostratified with cilia and goblet cells. This process involves inhaling air and conducting it to the lungs where gas exchange occurs in which oxygen is extracted from the air and carbon dioxide expelled from the body. The lung bud divides into two bronchial buds which divide and form secondary and tertiary bronchi. Food moves along the digestive system from the mouth where it is ingested to the anus where the undigested and unabsorbed remnants of food and some additional waste are eliminated.
