6.1 Flashcards
your digestive system is coupled with your
nervous systems
digestive system
circulatory system
circulatory system
what is the major function of respiratory system
supply o2 for cellular respiration and remove co2 waste product from cellular respiration
what are the four processes of respiration
respiratory systems
1.pulmonary ventilation
2.external respiration
circulatory system
3. transport o2 and co2 in blood
4. internal respiration
what is pulmonary ventilation
breathing: movement of air in and out of lungs (conductive zone, no gas exchange with blood or tissue)
external respiration
exchange of o2 and co2 between lungs and blood- respiratory zone, gas exchange
transport
cardiovascular system: o2 and co2 in blood to and from the lungs to tissue
internal respiration
exchange of o2 and co2 between blood vessels and tissues
major respiratory organs: conducting zone
nose, nasal cavity, pharynx, larynx, trachea, bronchi, bronchioles, terminals bronchioles
major respiratory organs: respiratory zone
respiratory bronchioles, alveolar ducts & alveoli
function of conducting zones
passageway
cleanse(filter)
moistens and humidify air
olfactory zone
resonating chamber for speech
nose
external portion
filters and cleanse inspired air
airway
moistens and warms air
olfactory speech
speech chamber
what are the two regions of the nose
external nose and nasal cavity
external nose
includes root (bridge, dorsum nasi, apex, naris)
nasal and frontal (bridge and root)
maxillary bones laterally (upper jaw and cheek)
plates of hyaline cartilage inferior
nasal septum
divided by?
posteriorly by?
perpendicular plate
divided by midline nasal septum (formed by septal cartilage)
vomer bone
ethmoid bone
choanae
where nasal cavity turns into nasopharynx
roof: ethmoid and sphenoid bone
floor: hard palate(bone) and soft palate(muscle)
