Respiratory System


the overall exchange os gases between the atomsphere, the blood, & the cells

Nasal Septum

the vertical partition that divdes the nose into the left & right nasal cavitites is called:


are also called nares

Cardiovascular System & Respiratory System

Share the responsibility of supplying oxygen & elimanating carbon dixoide gas from & to the body.


the anterior portion of the nasal cavities just inside the nostrils is called:

Thyroid Cartliage

is the largest piece ofd cartilage & is also known as the Adams Apple.


is closed off when we swallow so that foods & liquids are routed posteriorly into the esophagus & are kept out of the trachea anteriorly.

True Vocal Cords

sound orginates from the vibration of these

Vestibular Folds

are also known as the false vocal cords, and are located in the larynx.

Pleural Fluid

the fluid within the pleural cavity prevents fricton between the pleural membranes & allows them to slide past each other during respiration.

Inhalation, or Inspiration

Is the movement of air into the lungs.


is an active process


is a passive process


a progressively degerative disease characterized by the destruction of elasticity of the alveolar walls, resulting in the decreases ability of the lungs to expel are is known as:

respiratory distress syndrome

Hyaline membrane disease, common in premature infants & characterized by inadequate ventilation & tirung if the respiratory muscles.


an infection of the lungs characterized by fever, chest pain, fluid in the lungs & difficulty in breathing.

Cystic Fibrosis

an inherited disease affectingf the secretory cells of the lungs, which leads to obstruction of the airway due to thick mucus accumulating in the lungs.

Pulmonary Fibrosis

also known as black lung


Inflammation of the bronchi, which causes swelling of the mucous membrane lining of the bronchial tubes.


the overall exchange of gases between the atomsphere, the blood & the cells.

External Respiration

the exchange of gases between the lungs & the blood.

Internal Respiration

the exchange of gases between the blood & the body cells.

Pleural Membrane

The double folded serous membrane that encloses & protects the lungs.

Pleural Cavity

the space between the 2 layers of the pleural, which contains a lubricating fluid that decreases the friction between the membranes during the breathing process.

Whooping cough

a term for pertussis

nasal septum

The verticle partition that divdes the nose into right & left nasal cavities.

Bronchogenic Carcinoma

Teh most common type of pulmonary cancer.


also known as Whooping cough.

Black Lung Disease

Pulmonary Fibrosis is also known as:


an insision into the trachea, creating a new opening for air to enter.


the movement of air between the atomsphere & the lungsis known as breathing or:


the tubular structure that serves as a passageway for both air & food:

Voice Box

This is also known as the Larynx.


alson known as the trachea

Visceral pleura

the inner layer of the pleural membrane that attaches directly to the lungs.

Parietal pleura

the outter layerof the pleural membrane that attaches to the lung to the wall of thoracic cavity.


The openings into the external nose, also known as the external nares.


the u-shaped bone located just above the larynx, serves as points of attachment for the muscles of the tounge & throat.


the smaller air passages that branch out into the segments of the lobe of the lungs.

Respiratory Distress Syndrome

Hyaline menbrane disease.


the part of the pharynx that houses the pharyngeal tonsils, the 2 internal nares, & the openings to the 2 eustachian tubes.

**78% nitrogen, 21% oxygen, & 0.04% carbon dixoide

the following is true ambient air

PCO2 of 45mm Hg, & PO2 of 40 mm of Hg

Represents the partical pressure of pulmonary artery capillary blood.

Adams Apple

the largest piece of thyroid cartilage in the larynx.

Nasal Septum

is the verticle partition that divides the inside of the nose into the right & left nasal cavities.


the surface of the respiratory membrane inside each alveolus is coated with a fluid, consisting of a mixture of lipoproteins.


the1st process of respiration is breathing or ___________, which is the movement of air between the atomsphere and the lungs.

External Respiration

is the exchange of gases between the lungs & the blood.

Internal Respiration

The exchange of gases between the blood & the body cells

Partical Pressure

of a gas is the amount of pressure that gas contributes to the total pressure & is directly proportional to the concentration of the gas in the mixture.


or throat, serves as a passageway for both air & food.


is also known as the voice box


is also known as the windpipe.

Pleura Membrane

is a serous membrane that encloses & protects the lungs.


are grape like out-pouchings located at the ends of the respiratory bronchioles.

Parietal Pleura

is the outer layer of the Pleural membrane that attches the lungs to the wall of the Thoracic Cavity.


Inspiration involves a ________________in gas pressure causing a vacum that sucks air into the lungs.

eustachian tubes



opening from mouth

vestibular folds
