Nasal cavity
Nasal cavity
The main passageway for air to enter the respiratory system. It filters, warms, and humidifies inhaled air.
Pharynx
Pharynx
The tube that connects the nasal cavity and oral cavity to the larynx. It serves as a common pathway for air and food.
Larynx
Larynx
The airway connecting the pharynx to the trachea. It contains the vocal cords responsible for sound production.

Study Notes
Respiratory System Structures
- The respiratory system encompasses various structures involved in breathing
- The nasal cavity and nostrils are the primary entry points for inhaled air
- The oral cavity also contributes to air intake
- The pharynx is a common passageway for both air and food
- The larynx, commonly known as the voice box, plays a role in sound production
- The trachea, or windpipe, is a tube that carries air to the lungs
- The bronchi are the two main branches of the trachea, leading to the lungs
- The right and left main bronchi further divide into smaller branches known as bronchioles
- The lungs are the primary organs of gas exchange, composed of alveoli, the tiny air sacs where oxygen and carbon dioxide are exchanged
- The diaphragm is a dome-shaped muscle essential for inhalation and exhalation.
