Definition
| chronic, obstructivelung disease that affects the bronchi and bronchioles, making breathing difficult or impossible because of reduced air flow (7.3) |
|
|
Term
|
Definition
| inspiration and expiration; inspiration moves air from the external environment into the lungs, and expiration moves from the lungs back to the external environment |
|
|
Term
|
Definition
in a mammal, the passageway that branches from the bronchi into the separate lobes of the lungs; divides into smaller and smaller passageways that carry air into all portions of the lungs (7.1) |
|
|
Term
|
Definition
inflammation of the bronchi; can be acute or chronic(7.3) |
|
|
Term
|
Definition

cancer-causing agent (7.3) |
|
|
Term
|
Definition
|
|
Term
|
Definition
| a genetic condition that disrupts the function of the cells lining the passageways of the lungs; causes the usually thin mucus and liquid coating on the insides of the of the lungs to becomes very thick and sticky, leading to breathing problems (7.3) |
|
|
Term
|
Definition
| in mammals, a muscle layer that separates the region of the lungs (thoracic cavity) from the region of the stomach and liver (abdominal cavity); contraction contributes to inspiration by increasing the volume of the thoracic cavity (7.2) |
|
|
Term
|
Definition
| obstructive respiratory disorder in which the walls of the alveoli break down and lose their elasticity; reduces the surface area for gas exchange and causes oxygen shortages in the tissues (7.3) |
|
|
Term
|
Definition
| in mammals, flap of cartilage located over the entrance to the trachea (called the glottis); closes during swallowing to prevent food from entering the respiratory tract (7.1) |
|
|
Term
|
Definition
| movement of air out of the lungs during breathing; also known as expiration (7.2) |
|
|
Term
| Expiratory Reserve Volume |
|
Definition
| additional volume of air that can be forced out of the lungs, beyond a regular, or tidal, exhalation (7.2) |
|
|
Term
|
Definition
| exchange of oxygen and carbon dioxide between the air and the blood; takes place in the lungs; compare internal respiration (7.2) |
|
|
Term
|
Definition
| in mammals, the opening of the trachea through which air enters the larynx (7.1) |
|
|
Term
|
Definition
| movement of air into the lungs during breathing; also known as inspiration (7.2) |
|
|
Term
| Inspiratory Reserve Volume |
|
Definition
| additional volume of air that can be taken in by the lungs, beyond a regular, or tidal, inhalation(7.2) |
|
|
Term
|
Definition
| exchange of oxygen and carbon dioxide between the body's tissue cells and the blood (7.2) |
|
|
Term
|
Definition
| inflammation of the larynx (7.3) |
|
|
Term
|
Definition
| in mammals, a structure within the upper respiratory tract that contains the vocal cords; also commonly known as voice box (7.1) |
|
|
Term
|
Definition
| uncontrolled and invasive growth of abnormal cells in the lungs (7.3) |
|
|
Term
|
Definition
| passage from the nostrils to the back of the throat through which airs enters the body; serves to warm, moisten, and clean incoming air; lined with ciliated cells and mucus-secreting cells; also called the nasal cavity (7.2) |
|
|
Term
|
Definition
| structure located just behind the mouth that connects the mouth and nasal cavity to the larynx and esophagus; serves as the passageway for air into the respirtory system and for food and water into the digestive system; also known as throat (7.1) |
|
|
Term
|
Definition
| double-layered membrane that encloses the lungs; also referred to as pleura (7.1) |
|
|
Term
|
Definition
inflammation of the pleural membranes that surround the lungs (7.3) |
|
|
Term
|
Definition
| inflammation of the alveoli (air sacs) in the lungs (7.3) |
|
|
Term
|
Definition
| amount of gas that remains in the lungs and the passageways of the respiratory system even after a full exhalation (7.2) |
|
|
Term
|
Definition
| in animals, system responsible for gas exchange (bringing oxygen into the body and removing carbon dioxide from the body) (7.1) |
|
|
Term
|
Definition
| one of several muscles found between and along the inside surface of the ribs, extending down to the diaphragm; as a group, work with the diaphragm to move air in and out of the lungs; also known as intercostal muscle (7.2) |
|
|
Term
|
Definition
| volume of air that is inhaled and exhaled in a normal breathing movement when the body is at rest (7.2) |
|
|
Term
|
Definition
| infection of the tonsils, which are located in the pharynx |
|
|
Term
|
Definition
| in vertebrates, tube that carries air from the nasal passage or mouth to the lungs; also known as windpipe (7.1) |
|
|
Term
|
Definition
the total volume of gas that can be moved in or out of the lungs; equal to tidal volume + inspiratory reserve volume + expiratory reserve voume; also known as total lung volume capacity (7.2) |
