RESPIRATORY SYSTEM DISORDERS I (ANATOMY & PHYSIOLOGY)
RESPIRATORY SYSTEM MAIN FUNCTIONS
Provide oxygen to cells
Eliminate carbon dioxide
GAS EXCHANGE EXTERNAL/
INTERNAL
External
occurs between atmosphere and blood
Internal
occurs between blood and tissues
UPPER RESPIRATORY PASSAGEWAYS
air then passes through pharynx
pharynx
divided into three
regions:
nasopharynx (upper)
oropharynx (middle)
laryngopharynx (lower)
air enters through nose, past sinus cavities
LOWER RESPIRATORY PASSAGEWAYS AND LUNGS
trachea
is a tube with C-shaped cartilage rings (divides into two primary bronchi)
bronchial
system consists of bronchi, bronchioles, alveoli
larynx
contains vocal folds (allow speech)
lungs
left has two lobes
covered by pleura
parietal (outer)
visceral (inner)
right is larger and has three lobes
ROOTS FOR RESPIRATORY PASSAGEWAYS
pharyng/o
means pharynx
pharyngeal:
pertaining to the pharynx
laryng/o
means larynx
laryngospasm:
spasm of the larynx
rhin/o
means nose
rhinoplasty:
plastic repair of the nose
trache/o
means trachea
tracheotomy:
surgical opening into the trachea
nas/o
means nose
intranasal:
within the nose
bronch/o, bronch/i
means bronchus
bronchogenic:
originating in a bronchus
bronchiol
means bronchiole
bronchiolitis:
inflammatory bronchial reaction in young children and infants
ROOTS FOR LUNGS AND BREATHING
pleur/o
means pleura
pleurisy:
infection of the pleural cavity
pulm/o, pulmon/o
means lung
extrapulmonary:
outside the lungs
phrenic/o
means phrenic nerve
phrenicectomy:
partial excision of the phrenic nerve
pneumon/o
means lung
pneumonitis:
inflammation of the lung
phren/o
means diaphragm
phrenic:
pertaining to the diaphragm
pneum/o, pneumat/o
means air, gas, also respiration, lung
pneumothorax:
presence of air in the thorax
spir/o
means breathing
spirometry:
pulmonary function or breathing test
SUFFIXES FOR RESPIRATION
oxia
means level of oxygen
hypoxia:
decreased amount of oxygen in the tissues
capnia
means level of carbon dioxide
hypercapnia:
increased carbon dioxide in the tissues
pnea
means breathing
orthopnea:
breathlessness in the recumbent position relieved by sitting or standing
phonia
means voice
dysphonia:
difficulty in speaking
BREATHING
VENTILATION MADE UP OF:
inspiration
chest cavity enlarges
change in pressure causes air to be pulled in
phrenic nerve stimulates diaphragm to contract and flatten
expiration
lungs return to original size
air forced out
breathing muscles relax
GAS TRANSPORT
oxygen in blood
attached to hemoglobin in red blood cells
released to cells as needed
carbon dioxide mostly as carbonic acid
amount formed regulates blood pH
