Respiratory System
HST
Functions of the Respiratory System
• Take in O2 for use on a cellular level
• Expels waste such as CO2 & H2O from the cells
• Air flow over larynx make speech possible
Word Parts
nas/o alveo/lo
sinus/o pneum/o, pneumon/o, pneu
epiglott/o atel/o pulm/o
pharyng/o cyan/o pulmon/o
laryng/o -ectasis tachy-
trache/o phon/o thorac/o
bronch/o pleur/o -thorax
bronchi/o -pnea
The Respiratory Tract
• Upper Respiratory Tract = nose, mouth,
pharynx, larynx
epiglottis, trachea
• Lower Respiratory Tract = lungs,bronchi, bronchioles, alveoli
These are structures located
in the ______________cavity.
Opening of the Respiratory System
• Nares-
Nares - nasal openings
Functions of the Nose
• Mucous membranes -Warm, filter, moisten inhaled air
Cilia = tiny hairs inside the
nose
• *Move mucous & trapped particles into esophagus
• Mucous membranes
* line surfaces of
resp tract AND
*
secrete mucus to
moisten surfaces
and trap debris
Sinuses
-air filled cavities
warm & moisten air
-give *resonance to voice
*richness, significance
Pharynx
AKA the throat• Holds tonsils, adenoids• Receives air & food from mouth• Three divisions
* naso_____________
* oro ______________
* laryngo ___________
Larynx
AKA “Voice Box”
*Contains vocal cords*Produces sound for speech
• One of the nine cartilage rings that make up the larynx. AKA: the thyroid cartilage
Epiglottis
Prevents food
from entering
the trachea
during swallowing
glottis
AKA Windpipe
* Carries air between
pharynx & bronchi
*************
* Right & Left Bronchi
branch off trachea
to take air to lungs
***************
* Bronchioles carry air from bronchi to alveoli
Trachea, Bronchial Tree & Alveoli
Trachea
Bronchioles
Alveoli
*Site of cellular respiration i.e. O2 & CO2 are exchanged here*Occur in grape like clusters
Lungs
*Hold and support
structures necessary for
respiration
* R has 3 lobes(divisions)
* L has 2 lobes
Pleura
*Multilayered membrane
surrounding the lung
*Rich nerve & blood supply
*Protects & prevents
friction
intercostal muscles
Diaphragm •

• •
• Muscle that separated thoracic cavity from abdominal cavity• Contraction & relaxation causes respiration
Respiration• Inhalation• Exhalation
• Normal Adult respiratory rate: 14-20/min• Normal pediatric rate: 20 – 25
• Rate=• Volume=• Rhythm=
• Eupnea *Hyperventilation
• Tachypnea *Sleep Apnea
• Bradypnea *Cheyne Stokes
• Apnea Dyspnea (SOB)
• Hypernea Hyperventilation
• Hypopnea
