Study Notes

Respiratory System Components

Nostrils: Openings in the nose that allow air to enter the respiratory system.
Mouth: Serves as an alternative pathway for air, known as the oral cavity.

Key Structures

Larynx: Commonly referred to as the voice box, plays a crucial role in sound production.
Lungs: Pair of saclike organs in the chest responsible for gas exchange (oxygen and carbon dioxide).
Bronchi: Two main branches at the lower end of the trachea, directing air into each lung.

Airway Pathway

Trachea: Also known as the windpipe, it serves as the main airway connecting the larynx to the bronchi.
Bronchioles: The smallest branches of the bronchi, further distributing air throughout the lungs.

Respiratory Functions

Diaphragm: A large, flat muscle at the base of the chest cavity that is essential for inhalation and exhalation.
Alveoli: Microscopic air sacs with thin walls, where the exchange of oxygen and carbon dioxide occurs between air and blood.

Additional Structure

Pharynx: The throat area that serves as a passageway for both air and food, connecting the nasal cavity to the larynx.
