Term
Adenocarcinoma
Definition
A malignant tumor originating in glandular tissue.

malignant=cancerous
Term
Apnea
Definition
a brief period of time when you stop breathing
usually occurs during sleep
Term
Atlectasis
Definition
lung collapse
Term
Bicarbonate Ion
Definition
HCO3-) diffuses out of the red blood cell in exchange for the chlorine ion (CL-) in order to maintain the electrical neutrality of a slightly alkaline pH necessary for optimal cellular metabolism.
Term
Bronchial Sounds
Definition
produced by air rushing through the large respiratory passageways-the trachea and bronchi
Term
Cyanotic
Definition
A bluish discoloration of the skin and mucous membranes resulting from inadequate oxygenation of the blood.
Term
Dead Space Volume
Definition
air that enters the respiratory tract and remains in the conducting zone passageways that never reaches the alveoli.
Term
ERV
expiratory reserve volume
Definition
the amount of air that can be forcibily exhaled after a tidal expiration; approxiamtely 1200 ml
Term
Eupnea
Definition
the normal respiratory rate
Term
Hypernea
Definition
Easy, normal breathing
Term
Hyperventillation
Definition
Abnormally fast or deep respiration, which results in the loss of carbon dioxide from the blood, thereby causing a fall in blood pressure, tingling of the extremities, and sometimes fainting.
Term
Hypoxia
Definition
a condition in which inadequate oxygen is available to tissues
Term
IRV
inspiratory reserve volume
Definition
the amount of air that can be taken in above and beyond the tidal volume
Term
Nonrespiratory air movement
Definition
reflex activities that modify change or interrupt the normal respiratory rhythym-such as coughing, sneezing, laughing, and crying
Term
Oxyhemoglobin
Definition
hemoglobin combined with oxygen
Term
Pneumothorax
Definition
the presence of air in the intrapleural space of the lung
normal volume is between 2100 and 3200 ml.
Term
Residual Volume
Definition
after expiration, there is about 1200 ml of air still in the lungs, and this air can not be voluntarily expelled.
allows for gas exchange to continue even between breaths and helps to keep the alveoli inflated.
Term
self-exciting inspiratory center
Definition
a pacemaker
Term
Squamous Cell Carcinoma
Definition
lung cancer that arises in the epithelium of the larger bronchi and tends to form msses that hollow out and bleed
Term
Tidal volume
Definition
amount of air inhale or exhaled during normal breathing; respiratory volume
Term
Vesicular breathing sounds
Definition
occur as air fills the alveoli; soft sounds that resemblr
Term
Vital Capacity
Definition
the volume of air that can be expelled from the lungs by forcible expiration after the deepest inspiration; total exchangeable air
Term
Small cell carcinoma
Definition
contains lymphocyte-like cells that originate in the main bronchi and grow aggressively in cords or small grapelike clusters within the mediastinum
