Pneumothorax
Air in the pleural cavity caused by a puncture of the lung or chest wall and leading to a lung collapse is known as ___ ?
Residual Volume RV
Amount of air REMAINING in the lungs after forceful and complete expiration is known as the ___ ___ ?
Forced Vital Capacity FVC
Amount of air that can be expelled when the subject takes the deepest possible inspiration and forcefully expires as completely and rapidly as possible is known as ___ ___ ___ ?
Expiratory Reserve Volume ERV
Amount of air that can be forcefully expired after a normal tidal volume expiration is known as the ___ ___ ___ ?
Inspiratory Reserve Volume IRV
Amount of air that can be forcefully inspired after a normal tidal volume inspiration is known as the ___ ___ ___ ?
Type 2
Surfactant is made by which type of alveolar cells ?
Respiration rate
The FREQUENCY of breathing within 1 MINUTE is also called ___ ___ ?
Tidal Volume TV
The amount of air (in milliliters) that is moved in or out of the lungs with each breath under resting conditions is known as ___ ___?
Lung Compliance
The ease with which the lung is able to fill with air, is affected by the Distensibility (elastic recoil) of the lung tissue and the surface tension in the alveoli, is known as ___ ___ ?
Emphysema
The loss of elastic recoil in lung tissue that destroys the walls of the alveoli, usually associated with smoking. This condition is known as ___ ?
Ventilation
The movement of air into and out of the lungs is known as breathing or ___ ?
Alveolar Surface tension
The polar attraction of liquids, water molecules are more attracted to each other rather than the molecules in gas is called Cohesion or ___ ___ ___ ?
Transmural pressure
The pressure difference that occurs across the airway wall, keeping it in a state of elastic tension is called ___ ___ ?
Intrapleural pressure
The pressure in the pleural cavity is called the ___ __ ?
Lung Elasticity
The tendency of the lungs to return to their original size after distension is called ___ ___ ?
Partial Pressure
The term used to describe the amount of gas in air or dissolved in fluid, such as blood that contribute to the total pressure is known as the ___ ___ ?
Minute Ventilation
Total VOLUME of air inhaled and exhaled each MINUTE is called ___ ___ ? Note: ? (ml/min) = TV (ml/breath) x BPM (breaths/min)
Forced Expiration
When abdominal wall muscles and the internal intercostal muscles also contract during expiration to force additional air from the lungs is it called ___ ___?
Inspiration
When the diaphragm and external intercostal muscles contract, the volume in the thoracic cavity increases , allowing atm gas to enter the lungs, is a process called ___ ? Hint: Phase 1 of breathing
Expiration
When the diaphragm and external intercostal muscles relax, the pressure in the thoracic cavity increases as the volume decreases, forcing air out of the lungs, is a process called ___ ? Hint: Phase 2 of breathing
Chloride Shift
carbonic anhydrase is in RBC's so at the tissues to balance bicarbonate ions diffusing out of cells (because CO2 enters RBC, carbonic anhydrase converts, bicarbonate diffuses out to plasma) (vice versa at lungs), Cl- enters. This process is known as ___ ___ ?
Active
Inspiration is considered an (active/passive) process?
Total Lung Capacity TLC
Maximum amount of air contained in lungs after a maximum inspiratory effort is called the ___ ___ ___ ? Hint: ??? = TV + IRV + ERV + RV
Vital Capacity VC
Maximum amount of air that can be inspired and then expired with maximal effort is called the ___ ___ ? Hint: ?? = TV + IRV + ERC
Forced Expiratory Volume FEV1
Measures the amount of the vital capacity that is expired during the first second of the FVC test and known as ___ ___ ___ ?
Atelectasis
A collapsed lung is also termed ___ ?
Surfactant
A detergent like mixture of lipids and proteins that DECREASES surface tension by reducing the attraction of water molecules to each other is known as ___ ?
oscilloscope
A device which converts sound waves into an electrical signal on a screen.
Acute Asthma Attack
Bronchiole smooth muscle spasms and airways become constricted, reducing diameter, also becoming clogged with thick mucus secretions. This condition is known as ___ ___ ___ ?
Passive
Expiration is considered an (active/passive) process?
