25
What is asthma?
inflammation in airways - wheezing - coughing - tightness in chest
26
What is atelectasis?
collapse of part or all of a lung caused by a blockage of the air passages - caused by COPD, pleurisy (inflamed pleura), lung cancer
27
What is bronchitis?
inflammation of the bronchi often due to infection - yellow-gray/green mucus - fever - coughing
28
What is COPD?
group of lung disorders that limit airflow to lungs and usually cause enlargement of the alveoli - caused by smoking and pollutants
29
What is emphysema?
damage to the alveoli from smoking - most common types of COPD
30
What is legionnaires disease?
From legionella bacteria found in contaminated water of air conditioning systems
31
What is the sclera?
white portion of eye
32
What is pupil?
center opening
33
What is cornea?
clear covering in the center of the eye
34
What is iris?
colored portion
35
What is retina?
captures vision input
36
What is conjunctiva?
clear coating on the outside of the eye
37
What are the lens?
allows the eye to focus on objects at varying distances
38
What is accommodation?
ability of lens to change shape
39
What is refraction?
bending of light that enters the eye to focus it on the retina - done by cornea
40
What is astigmatism?
cornea or lens with abnormal shape
41
What is myopia?
dysfunction of the lens - nearsightedness
42
What is hyperopia?
dysfunction of lens - farsightedness

What is blepharitis?
inflammation of the eyelid
44
What is pink eye?
conjunctivitis
45
What is the pinna?
auricle - outer ear structure
46
What are the ossicles?
malleus, incus, stapes - bones of the ear
47
What is the cochlea?
hearing receptor
48
What is the labyrinth?
inner ear
49
What is the organ of corti?
organ of hearing
50
What is the tympanic membrane?
eardrum - sound waves cause it to vibrate = separates outer ear from middle ear - detects balance
51
What is the eustachain tube?
connects throat to the middle ear
52
What is hearing loss?
deafness
53
What is conductive hearing loss?
blockage of sound waves
54
What is sensorineural hearing loss?
damage to auditory nerve
55
What is cerumen (earwax) impaction?
buildup of wax within external auditory canal with some degree of hearing loss due to blocked sound waves
56
What is meniere's disease?
inner ear problem - starts in people between 30-50 years old - dizziness - ringing in the ear - sensitivity to loud sounds
57
What is otosclerosis?
immobilization of the stapes due to scaring - common cause of conductive hearing loss - hardening of middle ear bone
58
What is presbycusis?
age-related hearing loss
59
What is otitis externa?
outer ear infection - swimmer's ear
60
What is otitis media?
middle ear infection - needs antibiotics
61
What is otitis interna?
