COMPLETE SOLUTIONS VERIFIED
What does the cardiovascular system and the respiratory system do?
supply O2 to the body and removes CO2
3 parts of respiration
pulmonary ventilation, external respiration, and internal respiration
pulmonary ventilation
movement of air into and out of the lungs
ventilation of lungs is
breathing
external respiration
O2 and CO2 exchange between the air and in the lungs and blood in the capillaries
internal respiration
O2 and CO2 exchange between the blood and the cells, O2 utilization and CO2
production by the cell metabolism (cellular respiration)
respiratory system anatomy contains
upper respiratory system, lower respiratory system, and conducting zone
upper respiratory system
nose and pharynx
lower respiratory system
larynx, trachea, bronchi, lungs
pathway of air movement
, nose or mouth to pharynx through larynx to trachea to R+L primary bronchi through
lungs to smaller bronchi to bronchioles to alveoli
alevoli
small air sacs in which gaseous exchange between air and blood occurs (respiratory
zone)
conducting zone
(airflow only) mouth/nose then air to bronchioles
otorhinolaryngologist
...
pulmonologist
...
the nose contains
the external nose and nasal cavity
2 parts of external nose (framework)
superior and inferior
superior external nose (framework)
nasal parts of the maxillae and frontal bones
inferior external nose (framework)
cartilage plates held by CT
Nasal cavity extends from
the nostrils (external nares) to the nasopharynx posteriorly
nasal cavity divided by
nasal septum into Rt and Lt chambers
