True or false.
The lungs are symmetrical.
False
Hilum
the "root" of the lung
healthy lung tissue is what color
peachy/pink color
pleurae
membranes that surround the lungs and the cavity around the lungs
visceral pleura
layer of pleura that faces/covers the lung
parietal pleura
outer layer of pleura lying closer to the ribs and chest wall that covers the surface around the lungs
,pleural space/cavity
Space between the visceral and parietal pleural membranes (small)
typically empty but has a small amount of fluid that allows for frictionless breathing
when diseased, this space can fill with air or fluid
what is the function of the pleurae
the pleurae help reduce friction and help with inflation and inhalation
compartmentalize, protect, and lubricate the lungs
the three main functions of the respiratory system
1) air conduction
2) air filtration
3) exchange of gases aka respiration
other things respiratory system has roles in
vocalization, sense of smell. body's pH regulation
, structures in the respiratory system
nasal cavity, pharynx, larynx, trachea, bronchi, lungs
what happens to air as it goes from outside the body to the lungs
air is filtered so it has no debris
air is warmed to body temp
air is humidified and becomes saturated with water
nasal cavities aka fossae are composed of what
none and cartilage
nasal septum
a wall of cartilage that divides the nose into two equal sections of left and right fossae
vestibule
most external part of nasal cavity just inside the nostrils
vestibule lining
