Upper Respiratory Tract

100

Located where

Thoracic cavity

200

Exchange of gases between blood and the tissues

Internal Respiration

200

Composed of larynx, trachea, bronchus, and the lungs

Lower Respiratory Tract

200

Right lung is divided by two fissures to form the

Superior, Middle, and Inferior lobes

300

exchange of gases between the lungs and the blood

External Respiration

300
The two nasal cavities are separated by the

Nasal septum

300

Each lung is enclosed in a double-layered serous membrane called the

Pleural membrane

400

Allows the body to inhale or exhale air

Pulmonary Ventilation

400

A cartilaginous flap, located on top of glottis and at the base of the tongue

Epiglottis

400

Left Lung is divided by a single fissure to form

Superior and inferior lobes

500

Exchange of air between the atmosphere and the lungs

Pulmonary Ventilation

500

The trachea bifurcates to form

The right and left primary bronchi

500

Within each lung, the primary bronchus divides and eventually forms

The alveolar ducts
