Respiratory System

HST

Page 3: Just Breathe

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

Page 4: Just Breathe

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

Page 5: Just Breathe

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.

Page 6: Just Breathe

Opening of the Respiratory System

• Nares-

Nares - nasal openings

Page 7: Just Breathe

Nasal Septum

Separates R & L nares

Page 8: Just Breathe

Functions of the Nose

• Mucous membranes -Warm, filter, moisten inhaled air

Page 9: Just Breathe

Cilia = tiny hairs inside the

nose

• *Move mucous & trapped particles into esophagus

Page 10: Just Breathe

• Mucous membranes

* line surfaces of

resp tract AND

*

secrete mucus to

moisten surfaces

and trap debris

Page 11: Just Breathe

Sinuses

-air filled cavities

warm & moisten air

-give *resonance to voice

*richness, significance

Page 12: Just Breathe

Pharynx

AKA the throat• Holds tonsils, adenoids• Receives air & food from mouth• Three divisions

* naso_____________

* oro ______________

* laryngo ___________

Page 13: Just Breathe

Larynx

AKA “Voice Box”

*Contains vocal cords*Produces sound for speech

Page 14: Just Breathe

• One of the nine cartilage rings that make up the larynx. AKA: the thyroid cartilage

Page 15: Just Breathe

Epiglottis

Prevents food

from entering

the trachea

during swallowing

glottis

Page 16: Just Breathe

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

Page 17: Just Breathe

Alveoli

*Site of cellular respiration i.e. O2 & CO2 are exchanged here*Occur in grape like clusters

Page 18: Just Breathe

Lungs

*Hold and support

structures necessary for

respiration

* R has 3 lobes(divisions)

* L has 2 lobes

Page 19: Just Breathe

Pleura

*Multilayered membrane

surrounding the lung

*Rich nerve & blood supply

*Protects & prevents

friction

intercostal muscles

Page 20: Just Breathe

Diaphragm •

» »

• •

• Muscle that separated thoracic cavity from abdominal cavity• Contraction & relaxation causes respiration

Page 21: Just Breathe

Respiration• Inhalation• Exhalation

• Normal Adult respiratory rate: 14-20/min• Normal pediatric rate: 20 – 25

• Rate=• Volume=• Rhythm=

Page 22: Just Breathe

• Eupnea *Hyperventilation

• Tachypnea *Sleep Apnea

• Bradypnea *Cheyne Stokes

• Apnea Dyspnea (SOB)

• Hypernea Hyperventilation

• Hypopnea
