Components of the Human Respiratory System
An overview of the major organs of the human respiratory system and their division into conducting and respiratory parts.
What is Components of the Human Respiratory System?
A cartilaginous tube that connects the larynx to the bronchi of the lungs, serving as the main passage for air.
Key points
- Identify the major organs of the human respiratory system.
- Differentiate between the conducting and respiratory parts of the system.
- Describe the functions of each component of the conducting part.
- Explain the role of alveoli in gas exchange.
Common exam trap
Confusing the roles of the pharynx and larynx.
Definitions
- Term
Trachea
- Meaning
A cartilaginous tube that connects the larynx to the bronchi of the lungs, serving as the main passage for air.
- Term
Alveoli
- Meaning
Tiny air sacs in the lungs where the exchange of oxygen and carbon dioxide takes place.
- Term

- Meaning
A flap of cartilage at the base of the tongue, positioned to cover the opening of the larynx during swallowing.
- Term
Pleura
- Meaning
A pair of serous membranes lining the thoracic cavity and covering the lungs.
