Respiratory anatomy.
What are the Basic function of the respiratory system.
Supplies body with oxygen
disposes of carbon dioxide.
Conducting Zone
Conducts air into the respiratory zone.
(nose, pharynx, larynx, trachea, primary bronchi)
Extensively branching respiratory passageways.
primary bronchi, right bronchi, left bronchi, secondary bronchi, tertiary bronchi, bronchioles, terminal bronchioles, alveolar sacs, alveolar ducts.
Bronchi's.
Superior, middle, and inferior lobes
fissures, oblique and horizontal
Right lung
Physical movement of air in and out of the lungs
Ventilation (respiratory function)
Respiratory Zone
site of gas exchange
(Terminal Bronchioles, Alveoli)
300 million account for tremendous surface area of the lungs. Has type 1 and type 2 cells.
Alveoli.
Between air and blood in the lungs, and between blood and body tissues.
Gas Exchange
Funnel shapes passageway, connects nasal cavity to the mouth.
Divided into three sections by location.
Nasopharynx
Oropharynx
laryngopharynx
The Pharynx.
Why are Alveoli a good site for exchange of respiratory gases.
The walls of the alveoli share a membrane with the capillaries. That's how close they are. This lets oxygen and carbon dioxide diffuse, or move freely, between the respiratory system and the bloodstream
Cellular Respiration. (makes ATP)
02 utilization.
Voice Production, Provides an open airway for air flow.
Routes air and food into proper channels.
The Larynx.
What are the major landmarks of the lungs
apex, base, hilum, root
Nose, Nasal Cavity, Paranasal Sinuses.
Pharynx, Larynx, Trachea.
Bronchi, smaller bronchioles.
Lungs Alveoli
Organs of the respiratory system.
(Windpipe) Extends from pharynx into the primary bronchi in the mid thorax.
C-shaped hyaline cartilage ring keeps airway open.
The Trachea.
Superior inferior lobes
fissure and oblique
Left Lung
