Anatomy Of Upper Respiratory Tract

The human respiratory system is divided into the upper and lower respiratory tracts. The airway which includes the nose mouth pharynx larynx trachea bronchi and bronchioles carries air between the lungs and the bodys exterior.

The respiratory system is divided into two main components.

Anatomy of upper respiratory tract. The lower airways or lower respiratory tract includes the portion of the larynx below the vocal folds trachea bronchi and bronchioles. Lying just after the nostrils are the two nasal cavities lined with mucous membrane and tiny hair like projections called cilia 6. Mucous membranes lining upper respiratory structures trap some foreign particles including smoke and other pollutants before the air travels down to the lungs.

Two pairs of vocal folds are found in the larynx. The rear of the laryngopharynx merges with the esophagus to continue the digestive tract. There are 3 major parts of the respiratory system.

When you inhale beta adrenergic medicine like ventolin or xopenex the medicine binds to these receptors and the reaction causes bronchial muscles to relax opening the airway and making breathing easier. The upper airways or upper respiratory tract includes the nose and nasal passages paranasal sinuses the pharynx and the portion of the larynx above the vocal folds cords. Anatomy of lower and upper respiratory system.

Receptors on the bronchial walls are tiny receptors. Upper respiratory tract the major passages and structures of the upper respiratory tract include the nose or nostrils nasal cavity mouth throat pharynx and voice box larynx. The upper respiratory system or upper respiratory tract consists of the nose and nasal cavity the pharynx and the larynx.

There are a number of differences and similarities macroscopically and microscopically between the species. These structures allow us to breathe and speak. Which pair are the true vocal cords superior or inferior.

They warm and clean the air we inhale. Perhaps one of the most obvious examples of anatomical differences is in the structure of the turbinates. Composed of the nose the pharynx and the larynx the organs of the upper respiratory tract are located outside the chest cavity.

Inside the nose the sticky mucous membrane lining the nasal cavity traps dust particles. The airway the lungs and the muscles of respiration. The laryngopharynx is the posteriormost portion of the pharynx reaching from the hyoid to the cricoid cartilage.

The anatomical characteristics of the upper respiratory tract of various experimental animals and man are described. The nostrils the two round or oval holes below the external nose are the primary entrance into the human respiratory system 5.
