Respiratory System Functions and Structures

To produce mucus

To increase the air temperature

To filter large particles from the air

To humidify the air

To filter air using tiny hairs

To exchange gases with the blood

To divide air into the bronchi

To protect the airway with cartilage rings

Gas exchange increases

Airflow is blocked

Air is filtered more efficiently

Breathing becomes easier

To humidify the air

To trap debris and fine particles

To increase air temperature

To produce oxygen

Bronchial tubes

Mucus lining

Cartilage rings

Muscle fibers

Bronchioles divide air into the lungs

Bronchi are larger and have cartilage rings

Bronchioles have cartilage rings

Bronchi are smaller and more fragile

By exchanging gases with the blood

By dispersing airflow throughout the lungs

By humidifying air

By filtering air

To produce mucus

To exchange gases with the blood

To humidify air

To filter air

By filtering air

By dividing air into bronchioles

By changing shape with ribcage movement

By producing mucus

It helps filter air

It increases gas exchange efficiency

It humidifies the air

It supports the trachea
