Patho Respiratory Sy
Question | Answer |
---|---|
primary function is to obtain O2 from the air and deliver it to the lungs for exchange with CO2 and to the blood for distribution | Respiratory System |
coughing, sneezing, talking, and singing | Secondary functions of the respiratory system |
small air sacs in the lungs thin walled sacs surrounded by blood capillaries the site for O2 and CO2 exchange | Alveoli |
an oily lubricant that bathes the inner surfaces to reduce the surface tension in the lungs | Surfacant |
a waste product of cellular metabolism | CO2 |
the main muscles of inspiration, or inhalation | diaphragm and the external intercostals |
other muscles that assist exhalation | abdominal and internal intercostal |
the lungs are encased by a double membrane consisting of two layers called | pleura |
in between the pleura is the | pleural cavity |
acts as a vacuum and prevents the lungs from collapsing | intrapleural pressure |
the entire respiratory tract is lined with a mucous membrane called | epithelium |
hair like projections | cilia |
exert a sweeping action, preventing dust and foreign particles from reaching the lungs | cilia |
protects the lungs by moistening and warming inhaled air starting in the nasal cavity | mucous membrane |
dyspnea | labored breathing |
tachypnea | rapid breathing |
hemoptysis | coughing blood |
cyanosis | blue color in skin and nails |
oscillometry | a new test available to those as young as two years old |
distinguish patients who have persistently narrowed airways versus a confirmed diagnosis of asthma | oscillometry |
a key indicator of respiratory function | arterial blood gases |
sputum examination is helpful in the evaluation of | pneumonia, TB, and malignancies |
gram stains and cultures are useful in identifying | causative organisms, determining proper antibiotic treatment, and diagnosing TB and fungal lung infections |
permits visualization of the lungs and diaphragm during respiration | bronchoscopy, chest x-rays, and fluoroscopy |
air filled spaces that reduce the weight of the skill and contribute resonance to the voice | sinuses |
sinus cavities are referred to as | paranasal sinuses |
frontal, ethmoid, maxillary, and sphenoid | sinus cavities |
sinusitis | inflammation of the mucous membrane linings which causes pressure, pain, and often a headache |
ethmois sinus inflammation is more common in | children |
etiology of sinusitis | viruses, bacteria, and allergens |
results in painful headaches and facial swelling | chronic sinusitis |
noncancerous growths in the nasal or sinus passageway | nasal polyps |
the most common sleep disorder | obstructive sleep apnea |
interruption or hesitation of the normal breathing cycle during sleep is called | apnea |
the incidence is highest among middle aged overweight males | sleep apnea |
caused by a sensitivity to airborn allergens | hay fever |
triggers respiratory mucosa to secrete excessive mucus | allergens |
the most prevalent chronic condition in patients under age 18 | hay fever |
infections of these tissues lead to difficulty swallowing and redness and pain in the throat area | tonsis, pharynx, and larynx |
masses of lymphatic tissue embedded in the lateral mucous membranes of the midsection of the oropharynx | palatine tonsils |
tonsillectomy | removal of the tonsils and pharyngeal tonsils (adenoids) |
may contribute to short term pharyngitis | foreign objects, hot liquids, or spicy foods |
characterized by a red, purulent soar throat | strep throat |
characterized by hoarseness or aphonia | laryngitis |
causes laryngitis in young children | croup |
a viral infection of the upper respiratory system | influenza |
symptoms include - chills, fever, cough, sore throat, runny nose, chest pain, muscles aches, and gastrointestinal disorders | influenza |
chief among flu complications | pneumonia |
particularly serious in the elderly and chronically it, as well as young children | influenza |
common cold, sinusitis, nasal polyps, snoring and obstructive sleep apnea, hay fever (rhinitis), tonsillitis, pharyngitis, and laryngitis | upper respiratory diseases |
chronic bronchitis, chronic asthma, emphysema, cystic fibrosis, and pneumoconiosis | lower rrespiratory diseases |
irritants such as industrial fumes, automobile exhaust, viruses, and bacteria can cause | bronchitis |
bronchitis | inflammation of the bronchi that can be acute and chronic |
more serious in small children, the chronically ill, and the elderly | acute bronchitis |
characterized by chest pains, dyspnea, cough, fever, and sometimes chills | acute bronchitis |
sputum may contain pus | acute bronchitis |
indicated by coughing with sputum production lasting for at least 3 months for 2 consecutive years | chronic bronchitis |
more common in middle aged men than women | chronic bronchitis |
there is excessive secretion of mucus from the mucous glands of he bronchial mucosa lining | chronic bronchitis |
mucous glands hypertrophy, and the mucosa itself is thickened and inflamed | chronic bronchitis |
hypoxia | insufficient oxygenation of the tissues |
may be a complication of another respiratory infection | chronic bronchitis |
can result from long term exposure to air pollutants, cigarette smoking, or a complication of another infection | chronic bronchitis |
the flue or a common cold exacerbate | chronic bronchitis |
one of the most common chronic conditions worldwide | asthma |
bronchial asthma | chronic inflammation of the bronchi and bronchioles |
a disabling and debilitating disease caused by a restriction or obstruction | emphysema |
lungs lose their elasticity, and the lungs become filled with air that is high in CO2 | emphysema |
symptoms - suffocating feeling, inability to breathe unimpeded, and intense pain | emphysema |
atelectasis | a collapsed or airless condition of the lung |
pneumothorax | a collectivon of air or gas in the pleural cavityspirometer |
spirometer | an instrument that measures the movement and volume of air in and out of the lungs |
a barrel chest | emphysema |
a stethoscope placed on the chest detects abnormal respiratory sounds called | rales |
right side of the heart is weak, the blood is less saturated with O2 and cyanosis | emphysema |
an inherited disease that affects the exocrine glands | cystic fibrosis |
the most serious manifestation of cystic fibrosis is in | respiratory system |
symptoms - dyspnea, wheezing, persistent cough, and thick sputum | cystic fibrosis |
a common complication of cystic fibrosis | bronchiectasis |
brochiectasis | a sequela or residual effect of chronic inflammation and congestion |
most death involve younger adults and occur as a result of respiratory failure | cystic fibrosis |
lack of proper fat digestion results in a large, bulky, foul smelling stool | cystic fibrosis |
a hereditary disease that manifests in young children | cystic fibrosis |
transmitted through a recessive gene | cystic fibrosis |
sweat glands excrete excessive perspiration and large amounts of salt | cystic fibrosis |
confirms cystic fibrosis | sweat test |
