Upper Respiratory System
Upper Respiratory System
Mucous membranes lining of respiratory tract
that secrete mucus.
Upper Respiratory System
Mucus slimy secretion that
helps to warm, moisten, and filter air.
Upper Respiratory System

Lower Respiratory System
Trachea “windpipe” has rings of cartilage
that keep its shape.
Trachea
Lower Respiratory System
Bronchi branches at the bottom of the trachea that are contained in the lungs. Singular: bronchus
Bronchi
Lower Respiratory System
Bronchial tree term describing how branches of the bronchi get continually smaller, like a tree branch.
Lower Respiratory System
Bronchioles smallest branches of
the bronchial tree.
Bronchioles
Lower Respiratory System
Alveoli grape-like clusters at ends of bronchioles where exchange of gases occurs.
Alveoli
Lower Respiratory System
Lungs paired organs containing
bronchi that are divided into clearly defined lobes.
Lungs
Lower Respiratory System
Diaphragm a muscle located below the
lungs that contracts causing the lungs to fill with air.
