Solutions.
Alveoli correct answers tiny sacs of lung tissue specialized for the movement of gases between
air and blood
Functions of the pulmonary system correct answers ventilate alveoil, diffuse gases in and out of
blood, perfuse the lungs so that the organs and tissues of the body receive blood that is rich in O2
and low in CO2. (Through ventilation, diffusion and perfusion)
Ventilation correct answers Mechanical movement of air in and out of the lungs, not the same as
respiration's
Respiration correct answers Exchange of O2 and CO2 during cellular metabolism
pulmonary function tests (PFTs) correct answers tests that measure the ventilation mechanics of
the lungs: airway function, lung volume, and the capacity of the lungs to exchange oxygen and
carbon dioxide efficiently
Types of pulmonary function tests correct answers Simple spirometry
Pulmonary diffusing capacity
Residual volume
Oximetry
Capnography
Functional reserve capacity (FRC)
Total lung capacity
Arterial blood gas analysis
Thoracic imaging
hypercapnia correct answers excessive carbon dioxide in arterial blood
hypoxemia correct answers deficient amount of oxygen of arterial blood, alveoli may be
ventilated but not perfused
Kussmaul respirations correct answers Deep, rapid breathing; usually the result of an
accumulation of certain acids when insulin is not available in the body.
Cheyne-Stokes respiration correct answers pattern of breathing characterized by a gradual
increase of depth and sometimes rate to a maximum level, followed by a decrease, resulting in
apnea
spirometry correct answers Measures volume and flow of air inhaled and exhaled, plotted against
time during difficult breathing maneuvers, normal is 80% in 1 second
Aging and the Pulmonary System correct answers Loss of elastic recoil
, Stiffening of the chest wall
Alterations in gas exchange
Increases in flow resistance
Decreased exercise tolerance
Alveoli lose wall tissue and capillaries
Decrease PaO2 and ventilators reserve
pulmonary circulation correct answers flow of blood from the heart to the lungs and back to the
heart
bronchial circulation correct answers systemic circulation, delivers blood to and from the bronchi
and bronchioles
clubbing correct answers bulbous enlargement of distal phalanges of fingers and toes that occurs
with chronic cyanotic heart and lung conditions, graded 1-5 based in extent of nail hypertrophy
ventilation-perfusion mismatch correct answers occurs in conditions during which either the flow
of oxygen is limited in the alveoli or the circulation through the pulmonary capillary is
compromised, most common cause of hypoxemia
peripheral cyanosis correct answers cyanosis on the fingers and toes due to cold exposure,
anxiety, or inadequate circulation.
central cyanosis correct answers bluish discoloration of the skin or mucous membranes due to
decreased arterial concentration of O2
Dyspnea correct answers difficult or labored breathing
cyanosis correct answers A bluish discoloration of the skin and mucous membranes.
pneumothorax correct answers air in the pleural cavity caused by a puncture of the lung or chest
wall
types of pneumothorax correct answers spontaneous, traumatic, tension
pleural effusion correct answers abnormal accumulation of fluid in the pleural space
Types of pleural effusion correct answers -Transudative effusion (clear fluid, hydrothorax)
-Exudative effusion (often contains inflammatory cells)
-Empyema (purulent)
-Chylothorax (effusion of lymph in the thoracic cavity)
-Hemothorax (bloody)
