pulmonary ventilation
|
breathing-exchange of gases between the atmosphere and our lungs
|
|
|
inspiration
expiration |
-inhale
-exhale |
|
|
external respiration
internal respiration |
-exchange of gases in the lungs
-exchange of gases in the capillaries and the tissue |
|
|
functions of respiratory system
|
-provide required oxygen and remove carbon dioxide from body
-removal of carbon dioxide maintains blood PH -helps with production of sound -helps eliminate some water and heat -movement of respiratory muscles helps increase blood flow and lymphatic drainage |
|
|
upper respiratory parts
|
-nose and naval cavity
-paranasal sinus -pharynx |
|
|
lower respiratory parts
|
-larynx
-trachea -bronchi -lungs -diaphragm |
|
|
nose and naval cavity parts (3/7)
|
-nasal septum-vomer bone divided right and left sides of nose
-superior, middle, and inferior conchae subdivide nose into passageways -superior, middle, and inferior meatuses groove like passageways |
|
|
paranasal sinus parts (4)
|
-sphenoid sinus
-maxillary sinus -ethmoid sinus -frontal sinus |
|
|
pharynx parts (3)
|
-nasopharynx
-oropharynx -laryngopharynx |
|
|
larynx parts (4)
|
-thyroid cartalige (adams apple)
-epiglottis (flap) -glottis (doors for vocal cords) -true vocal cords (vibrate) |
|
|
Trachea part (1)
|
cartilagenous ring
|
|
|
bornchi parts (8)
|
where exchange of gases starts
-R+L Primary bronchi -R+L secondary bronchi -R+L tertiary bronchi -bronchioles -terminal bronchioles -respiratory bronchioles -alveolar duct -alveoli |
|
|
lung parts (6)
|
-R lung has 3 lobes
-L lung has 2 lobes -parietal pleura-superficial layer that lines the wall of thoracic cavity -visceral pleura-deep layer that covers lungs -pleural cavity-space around lungs -pleural fluid- reduces friction |
|
|
muscles of respiration
|
-diaphragm-major muscle of inspriration
-external intercostals-assists in inspriartion -internal intercostals-assists in expiration |
|
|
costal breathing
|
when breathing is hollow and chest moves in and out
|
|
|
diaphragmatic breathing
|
diapragm moves up and down and pushes abdominal contents outward
|
|
|
normal respiratory rate
|
adults= 12-18 breaths/min
children/elders= 18-20/min |
