Q

whats inspiration and the process?

A
  • process of breathing air in.
  • the diaphragm and intercostal muscle contract causing the thoracic cavity to be vacuum like. air rushes through airways to alveoli where exchange of gasses take place.

Q

expiration? process?

A
  • diaphragm and intercostal muscles relax

- air is forced out, then an increment of carbon dioxide in blood occurs causing center to increase.

what are the primary organs?
left lung and right lung
28
what's the diaphragm? what does it do?
-dome shaped fibrous tissue that separates the thoracic cavity from abdomen
29
thoracic volume?
pressure of increasing and decreasing muscles
30
what causes snoring?
narrowing of upper airway during sleep
31
asthma?
condition wear bronchial tubes inflame and result in obstructed -
32
cause of asthma?
allergy, infection and anxiety
33
symptoms of asthma?
tightness in chest, difficulty breathing, wheezing and coughing
34
treatment of asthma?
anti-inflammatory drugs, oxygen therapy
35
bronchitis?
mucus membrane in the lungs' bronchial passages becomes inflamed.
36
types of bronchitis?
acute and chronic
37
acute bronchitis cause? symptoms?
- caused by viruses or bacteria | - coughing and narrowing of bronchi bc of contraction
38
chronic bronchitis cause? symptoms?
- caused by frequent attacks of acute bronchitis and pollution - mucus, coughing, wheezing, chest pain and dyspnea
39
COPD cause?
chronic asthma , emphysema, tb, and chronic bronchitis
40
what's emphysema?
it's a non infectious chronic respiratory condition that occurs when walls of alveoli deteriorate and lose elasticity
41
how's emphysema caused and what are symptoms?
- caused by heavy smoking and exposure to air- pollution | - symptoms are dyspnea, suffocation , chronic coughing and cyanosis
42
whats epistaxis? treatment for it?
is a nose bleed that occurs when capillaries in nose become congested and bleed. -treatment is ice, pressure and leaning forward.
43
whats influenza? symptoms?
a contagious vial infection of upper respiratory system | - fever, chills, muscles, acne, cough and fatigle
44
laryngitis? treatment?
- inflammation of vocal cords | - treatment is rest, fluids, limited voice use
45
lung cancer
leading cause of cancer deaths in men and woman
46
whats pleurisy? symptoms? treatment?
- inflammation of pleura or membranes of lungs occurs in the conjuction with pneumonia - symptoms are sharp stabbing pains while breathing - treatment is, rest, meds to relive pain and inflammation
47
pneumonia? cause? symptoms?
- inflammation of the lungs - caused by bacteria and chemicals - symptoms are chills, fever, chest pain
48
rhinitis?
its a runny nose, inflammation of nasal mucous membrane
49
what's sinusitis? cause? symptoms?
- inflammation of mucous membrane lining - caused by bacteria/ viruses - symptoms are headache, pressure, thick nasal discharge and loss of voice
50
sleep apnea

52
TB (dormat)
no symptoms but is postive through the test
53
URI
contagious common cold
54
pleura
membrane or sac in-closed in each lung that allows lungs to expand during breathing
55
two types of pleura and location?
visceral (attached to lungs) | parietal (attached to chest wall)
56
pleural space
space filled with pleural fluid that prevents friction as lungs expand
57
Pleura? Location and function
Lungs, sack of fluid allows lungs to expand during breathing
58
Surfactant location? Function?
- inner surfaces of alveoli | - reduces surface tension of liquid.
59
Alveoli location? Function?
- lungs | - gets rid of carbon dioxide we don't need
60
Esophagus location? Function?
- throat | - pathway for food
61
Hilus location? Function?
- located in the center of the kidney | - blood vessels that enter leave the kidney
62
Bronches location? Function?
- it's in the windpipe in the lungs | - Shuttle air to and from lungs
63
Bronchiole location? Function?
- it's in the many bronchus near tissue. | - oxygen and carbon dioxide exchange
64
Thyroid cartilage location? Function?
- located in the neck | - regulates growth and development
