1
Respiration: Three Major Steps
Pulmonary ventilation
External respiration
Internal respiration
2
Moving air in and out of lungs
Pulmonary ventilation
3
Gas exchange between alveoli and blood
External respiration
4
Gas exchange between blood and cells
Internal respiration
5
upper respiratory system
Nose and pharynx
6
lower respiratory system
Larynx, trachea, bronchi, bronchioles, and lungs
7
consists of All airways that carry air to lungs
conduction zone
8
parts included in conduction zone
Nose, pharynx, trachea, larynx, bronchi, bronchioles, and terminal bronchioles
9
Sites within lungs where gas exchange occurs
respiratory zone
10
parts of the respiratory zone
Respiratory bronchioles, alveolar ducts, alveolar sacs, and alveoli
11
Warm, humidify, filter/trap dust and microbes
nose
12
Detect olfactory stimuli
nose
13
Modify vocal sounds
nose
14
“Voice box”
larynx
15
Made largely of cartilage
larynx
16
cartilages of the larynx
thyroid
cricoid
arytenoids
17
cartilage of larynx
: V-shaped
“Adam's apple”: projects more anteriorly in males
Vocal cords “strung” here (and to arytenoids
thyroid cartilage
18
leaf-shaped piece; covers airway
During swallowing, larynx moves up so ------ covers opening into trachea
epiglottis
19
cartilage of larynx
inferior most portion
cricoid
20
cartilage of larynx
superior to cricoid
Arytenoids
21
windpipe
trachea
22
Anterior to esophagus and thoracic vertebrae
Extends from end of larynx to primary bronchi
trachea
23
opening in trachea for tube
tracheostomy
24
enter the lungs medially
primary bronchiu
25
Measured by spirometer
Lung Volumes
26
volume of air that can be inhaled beyond tidal volume (TV)
Inspiratory reserve volume (IRV
27
volume of air that can be exhaled beyond TV
Expiratory reserve volume (ERV)
28
Air remaining in lungs after a maximum expiration
= residual volume (RV)
29
TV + IRV
Inspiratory capacity
