FINAL Flashcards
external landmark where trachea branches into the left and right mainstream bronchi?
angle of Louis
functions of lymph nodes
- produce lymphocytes and monocytes
- aide in autoimmune system and removal of bacteria and foreign materials
function of vessels
- remove protein molecules that leak out of capillaries
- remove excess fluid from interstitial spaces
mucocilliary transport is affected by?
-dehydration, smoking, suctioning, anesthetics, positive pressure ventilation
what is the furthest bronchial tree segment that can be seen during bronchoscopy?
segmental bronchi
space that separates the vocal cords?
glottis
pathway of pulmonary circulation?
pulmonary artery-> arterials -> capillary-> venuals -> veins
gel layer
lies on top of the cilia
sol layer
in the cilia
air that begins to enter the pleural cavity on the left side?
pneumothorax
larynx
protects against aspiration, generates sounds for speech, aides in valsalvas maneuver
pulmonary veins carry what type of blood?
oxygenated
pulmonary arteries carry what type of blood?
deoxygenated
properties of trachea
- has a c-shaped cartilage that protects it structure
- esophagus runs directly behind it
functions of sinuses
resonate sound, lighten the skull, produce mucous
structure arising from single terminal bronchiole can be known as?
primary lobule, acinus, lung parenchyma
large surface in upper resp tract that warms and humidifies air?
turbinates
Accessory Muscles of Expiration
ITIRED I- Internal Intercoastals T- Transfers Abdominius R- Rectus Abdominius I- Internal Obliques E- External Oliques D- Diaphragm
Accessory Muscles of Inspiration
STEPS S- Scalene Muscles T- Trepezius E- External Intercostals P- Pectorals S- Sternocleidomastoid Muscles
what breathing pattern would you expect to see if a patient arrives to the ER suffering from meningitis?
Biots
majority of frictional resistance in found in
trachea, right mainstem bronchi, segmental bronchi
if the diameter of an airway changes then what else Will change?
resistance
if the alveoli gets stiffer and fibrotic then what changes?
compliance
what pressure represents the pressure difference that maintains alveolar inflation?
transpulmonary
