List and discuss the major anatomical components of the respiratory system.

Step 1 of 3

The respiratory system is a collection of organs that are responsible for gaseous exchange in the body. The organs of the respiratory system are broadly classified into two categories as given below:

• The organs of the conducting zone

• The organs of the respiratory zone

The organs of the conducting zone: The conducting zone allows the air form the external environment to pass through it. It has the following organs:

• Nose and the nasal cavity

• Trachea

• Bronchial tree

• Bronchioles

The organs of the respiratory zone: The respiratory zone is the region where gaseous exchange takes place. The organs include the following:

• Respiratory bronchioles

• Alveolar ducts

• Alveolar sacs
