Term
visceral pleura
Definition
aka pulmonary pleura
a visceral serosa that lines the surface of each lung
Term
parietal pleura
Definition
a serosa that lines the walls of the thoracic cavity
Term
pleural fluid
Definition
slippery serous secretion that allows the lungs to glide easily over the thorax wall during breathing movements; produced by the pleural membrane
Term
pleurisy
Definition
inflammation of the pleura that results in stabbing pain with each breath
Term
bronchioles
Definition
aka-bronchial or respiratory tree

the smallest of the conducting passageways
Term
alveoli
Definition
small cavity; resembles bunches of grapes; makes up the bulk of the lungs
Term
respiratory zone
Definition
the only site for gass exchange; includes the respiratory bronchicles, alveolar ducts, alveolar sacs, and aveoli
Term
stroma
Definition
elastic, connective tissue that allows the lungs to recoil passively as we exhale
Term
alveolar pores
Definition
connect neighboring airsacs and provide alternative routes for air to reach alveoli, whose feeder bronchioles have been clogged by mucous or otherwise blocked.
Term
respiratory membrane
Definition
aka-air-blood barrier has gas flowing past one side and blood flowing past on the other
Term
alveolar macrophages
Definition
aka dust cells
wander in and out of the aveoli picking up bacteria, carbon particles, and other debris
Term
Heimlich Maneuver
Definition
a procedure in which the air in a person's own lungs is used to "pop-out" or expel an obstructing piece of food.
Term
Apex
Definition
The narrow, superior portion of each lung.
Term
Base
Definition
The area where the bottom part of the lung rests on the diaphragm
Term
Conducting Zone Structures
Definition
The conducting zone of the respiratory system is made up of the nose, pharynx, larynx, trachea, bronchi, bronchioles, and terminal bronchioles; their function is to filter, warm, and moisten air and conduct it into the lungs. It consists of a series of interconnecting cavities and tubes both outside and within the lungs. It is composed of the 1st through the 16th division of the respiratory tract.
Term
Expiration
Definition
The act of expelling air from the lungs; exhalation.
Term
External Respiration
Definition
the actual exchange of gases between the aveloi and the blood (pulmonary gas exchange)
Term
Inspiration
Definition
the drawing of air into the lungs; inhalation
Term
Internal respiration
Definition
the use of oxygen by body cells; also called cellular respiration
Term
Intrapleural pressure
Definition
the normal pressure within the the pleural space
Term
Intrapulmonary Volume
Definition
the volume within the lungs
Term
Lungs
Definition
The lungs are a pair of spongy, air-filled organs located on either side of the chest (thorax).
Term
Primary Bronchi
Definition
aka-main bronchi
A bronchus (plural bronchi, adjective bronchial) is a passage of airway in the respiratory tract that conducts air into the lungs. The bronchus branches into smaller tubes, which in turn become bronchioles. No gas exchange takes place in this part of the lungs
Term
Mediastinum
Definition
the region of the thoracic cavity between the lungs
Term
Pleural Space
Definition
The tiny area between the two layers of the pleura (the thin covering that protects and cushions the lungs). The pleural space is normally filled with a small amount of fluid.
Term
Pulmonary Ventillation
Definition
breathing; consists of inspiration and expiration
Term
Respiration
Definition
1. a. The act or process of inhaling and exhaling; breathing
Term
Respiratory Gas Transport
Definition
Oxygen and carbon dioxide is transported through the blood to and from the lungs and tissue cells of the body
