Process of gas exchange
Respiration
Composed of the nose and the pharynx
Upper Respiratory Tract
Located where
Thoracic cavity
Exchange of gases between blood and the tissues
Internal Respiration
Composed of larynx, trachea, bronchus, and the lungs
Lower Respiratory Tract
Right lung is divided by two fissures to form the
Superior, Middle, and Inferior lobes
exchange of gases between the lungs and the blood
External Respiration
Nasal septum
Each lung is enclosed in a double-layered serous membrane called the
Pleural membrane
Allows the body to inhale or exhale air
Pulmonary Ventilation
A cartilaginous flap, located on top of glottis and at the base of the tongue
Epiglottis
Left Lung is divided by a single fissure to form
Superior and inferior lobes
Exchange of air between the atmosphere and the lungs
Pulmonary Ventilation
The trachea bifurcates to form
The right and left primary bronchi
Within each lung, the primary bronchus divides and eventually forms
The alveolar ducts
