|
Tidal Volume |
The amount of air exhaled or inhaled during normal, quiet breathing. (400-500ml) |
|
|
Vital Capacity |
The maximum amount of air which can be forcibly exhaled immediately following a maximal inhalation. (4100ml) |
|
|
Expiratory Reserve Volume |
The amount of air that can be forcibly breathed out after normal expiration. (1100ml) |
|
|
Inspiratory Reserve Volume |
The amount of air that can be inhaled following normal TV inhalation. (3000ml) |
|
|
Residual Volume |
The amount of air remaining in the lungs after maximum forced expiration. (1200ml) |
|
|
Dead Space |
The volume of a breath that does not participate in gas exchange. |
|
|
Bronchitis |
Bacterial infection resulting in mucus discharge with much coughing. |
|
|
Pneumonia |
Parts of the lung become nonfunctional as they fill with fluid, mucus, and pus. |
|
|
Emphysema |
Destruction of lung tissue beginning with the collapse of the bronchioles and ending with the bursting of alveoli. |
|
|
Pulmonary Fibrosis |
Breathing capacity is seriously reduced due to the inhaling of particles such as asbestos, fiberglass, and sand. |
|
|
Intercostal Muscles (I/E) |
Contract/Relax |
|
|
Pleural Pressure (I/E) |
Negative so air can move into the lungs/Positive so air can move out of the lungs |
|
|
Chest Cavity Volume (I/E) |
Increases so the lungs can expand/Reduce |
|
|
Rib Cage (I/E) |
Moves up & out/Moves down & in |
|
|
Diaphragm (I/E) |
Contracts, flattens & pulls down/Relaxes & resumes its dome shape |
|
|
Oxyhemoglobin (HbO2) |
How oxygen moves around the body |
|
|
Deoxyhemoglobin (Hb) |
When oxygen leaves around the capillaries |
|
|
Carbaminohemoglobin (HbCO2) |
How CO2 goes to the lungs at a quick pace. |
|
|
Reduced Hemoglobin (HHb) |
Hemoglobin carrying hydrogen ions out of the body. |
|
|
Bicarbonate Ion (HCO3-) |
How CO2 moves around the body (made of CO2 & H2O); Causes you to breathe |
|
|
Nasal Cavities |
Filters, warms, and moistens |
|
|
Nasopharynx |
Passage of air from nose to throat |
|
|
Pharynx (throat) |
Connection to surrounding regions |
|
|
Epiglottis |
Passage of air |
|
|
Larynx (voice box) |
Sound production |
|
|
Trachea (windpipe) |
Passage of air to thoracic cavity. |
|
|
Bronchi |
Passage of air to each lung |
|
|
Bronchioles |
Passage of air to each alveolus |
|
|
Alveoli |
Air sacs for gas exchange |
|
|
Thoracic Cavity |
Body region containing heart & lungs; Clearly marked off from the abdomen by the diaphragm |
|
|
Breathing |
Entrance and exit of air into and out of the lungs |
|
|
External Respiration |
Exchange of gases (O2 & CO2) between air and blood. |
|
|
Internal Respiration |
Exchange of gases (O2 & CO2) between blood and tissue fluid. |
|
|
Cellular Respiration |
Production of ATP in cells. |
|
|
Pleural Membrane |
A double-layer of membranes lining the chest and surrounding the lungs that protect the lungs from germs, maintain an airtight seal, and prevent them from collapsing. |
