Adam's Apple

The middle cartilage of the Larynx (voice box)

Adenoids

A mass of lymphoid tissue in the Oro-pharynx.

Air cavities

Hollow spaces in the bones around the face that serve to moisturize and warm the air that you breathe.

Air Sacs

The tiny little air sacs in the lungs, also known as alveoli, and look like grapes in a cluster; where the exchange between the blood and the inspired air takes place.

Air Sinuses

Hollow spaces in the bones around the face that serve to moisturize and warm the air that you breathe.

Alveoli

The tiny little air sacs in the lungs that look like grapes in a cluster; where the exchange between the blood and the inspired air takes place.

Anterior Nares

the external openings of the nasal cavities.

Antrum

Hollow spaces in the bones around the face that serve to moisturize and warm the air that you breathe.

Antrum of Highmore

One of the paranasal sinuses found in the maxilla, also known as the maxillary air sinuses.

Bronchi

The tubes going to the lungs that eventually divide.

Bronchioles

Very small tubes that are the result of the division of the bronchi.

Cricoid Cartilage

The third and inferior-most cartilage of the larynx.

Epiglottis

The flap that covers the opening between the pharynx and the larynx and closes when you swallow.

Ethmoidal Air Sinuses

The paranasal sinus found in the ethmoid bone.

Eustachian Tubes

The passageway that connects the ears and the naso-pharynx, also known as the pharyngotympanic tubes.

External Respiration

The exchange between the inspired air in the alveoli of the lungs with the red blood cells.

Frontal Air Sinuses

The paranasal sinus found in the frontal bone.

Glottis

The opening between the pharynx and the larynx.

Hilum

The medial aspect of the lung where everything enters or exits.

Hilus

The medial aspect of the lung where everything enters or exits.

Internal Respiration

The exchange that occurs between the red blood cells and the tissues of the body.

Laryngo-pharynx

Located below the naso-pharynx and oro-pharynx, it divides at the bottom, anteriorly into the larynx and posteriorly into the esophagus.

Larynx

Also known as the voice box, it is made up of three cartilages and the vocal chords.

Left Lung

A chief organ of respiration consisting of two lobes and one transverse fissure.

Lungs

The chief organs of respiration and consists of two organs, right and left.

Maxillary Air Sinuses

A paranasal sinus found in the maxillas.

Nasal Concha

ridges in the nose, superior, middle, and inferior, also known as turbinate bones.

Nasal Septum

a partition of bone and cartilage between the nasal cavities.

Naso-pharynx

Connects the nasal cavity with the rest of the pharynx. Behind the soft palate and has two openings from the nose (posterior nares) and the passageways connecting the ears (eustachian tubes or pharyngotympanic tubes).

Nose

A structure of the respiratory system that consists of two nasal cavities separated by the nasal septum, anterior nares, posterior nares, ridges in the nose called the nasal concha (or turbinate bones).

Oro-pharynx

cavity formed by the pharynx at the back of the mouth where masses of lymphoid tissue, the tonsils and the adenoids, are located.

Paranasal Sinuses

(Antrum) air cavities or air sinuses (hollow spaces) in the bones around the face whose function is to moisturize and warm the air that you breathe.

Parietal Pleura

Serous membranes that lines the rib cage.

Pharyngo-tympanic Tubes

The passageway that connects the ears and the naso-pharynx, also known as the eustachian tubes.

Pharynx

the passageway behind the nose and mouth (both respiratory and digestive function)

Pharynx (naso-, oro- laryngo-)

the passageway behind the nose and mouth (both respiratory and digestive function). Naso-pharynx is behind the nose, Oro-pharynx is behind the mouth and below these is the Laryngo-pharynx.

Pleura

The serous membranes that cover the lungs.

Pleural Cavities

The cavities of the lungs.

Posterior Nares

openings between the nasal cavity and the nasopharynx

Respiration

The process for the exchange of oxygen from inspired air for the carbon dioxide produced as a result of metabolism in the body.

Right Lung

A chief organ of respiration consisting of three lobes and two transverse fissures.

Root of the Lung

The medial aspect of the lung where everything enters or exits.

Sphenoidal Air Sinuses

A paranasal sinus found in the sphenoid bone.

Thyroid Cartilage

The middle cartilage of the larynx, also called the adam's apple.

Tonsils

A mass of lymphoid tissue found in the oro-pharynx.

Trachea

Also known as the wind-pipe, it is the passageway for air below the larynx and above the bronchi, it bifurcates into the two bronchi inferiorly.

Transverse Fissures

Dividing lines on the surface of the lungs for the different lobes. Right lobe has two, left has one.

Turbinate Bones (superior, middle, and inferior)

ridges in the nose, superior, middle, and inferior, also known as nasal concha.

Visceral Pleura

The serous membranes that covers the lungs.

Vocal Chords

cords of tissue that are stretched from anterior to posterior through the larynx, connecting anteriorly to the thyroid cartilage.

Voice Box

(larynx), made up of three cartilages and the vocal chords.

Wind-pipe

(trachea) the passageway for air below the larynx and above the bronchi, it bifurcates into the two bronchi inferiorly.
