The process of taking in oxygen and releasing carbon dioxide. Essential for cellular respiration and energy production.

The energy molecule used by cells for various functions, including muscle contraction and nerve impulses.

The system responsible for gas exchange, bringing oxygen into the body and removing carbon dioxide.

The exchange of oxygen and carbon dioxide between the air in the alveoli and the blood.

Tiny air sacs in the lungs where gas exchange occurs.

The process of inhaling air into the lungs.

The process of exhaling air from the lungs.

The part of the respiratory system that carries air but does not participate in gas exchange (e.g., nose, trachea, bronchi).

The part of the respiratory system involved in gas exchange (e.g., alveoli).

The external part of the nose responsible for sensing odors.

The conchae are three bony scrolls within the nasal cavity covered by mucous membrane. They create turbulence in the air flow, ensuring most air contacts the mucous membrane for warming, filtering, and humidifying.

The meatus is a narrow passage beneath each nasal concha, allowing for air to flow through the nasal cavity, further contributing to the turbulence produced by the conchae.

The pharynx, also known as the throat, is a muscular funnel extending from the back of the nasal cavity to the larynx. It plays a crucial role in breathing, swallowing, and speech.

The larynx, or voice box, is a cartilaginous chamber responsible for keeping food and drink out of the airway and producing sound (phonation).

The epiglottis is a flap of tissue at the top of the larynx that acts as a lid, closing the airway during swallowing to prevent food and drink from entering the trachea.

The glottis refers to both the vocal cords and the opening between them. It is the name given to the space through which air passes. This space widens for breathing in (inspiration) and narrows during voice production (phonation), allowing for sound creation.

The trachea, also called the windpipe, is a tube that connects the larynx to the lungs, conveying air to and from the lungs. It is supported by C-shaped rings of cartilage, providing structural support and keeping the airway open.

The bronchi are the two branches of the trachea that lead to the right and left lungs. They further divide into smaller branches as they enter the lungs.

The lungs are paired organs within the chest cavity, responsible for gas exchange, taking in oxygen and releasing carbon dioxide. They are divided into lobes: the right has three, and the left has two. The lung's root features the main bronchus, blood vessels, lymphatic vessels, and nerves.

A two-layered serous membrane, the pleura surrounds the lungs. The visceral pleura directly covers the lung tissue while the parietal pleura covers the inner face of the chest cavity. The space between these layers is called the pleural cavity, filled with fluid to prevent friction.
