RESPIRATORY SYSTEM Flashcards
2 functions of the respiratory system
ventilation & diffusion
2 divisions of the respiratory system
upper and lower respiratory tract
what comprises the upper respiratory tract?
nose, pharynx, sinuses, mouth, larynx
what comprises the lower respiratory tract
trachea, bronchi, lungs, alveoli
- Serves as the opening for the pulling of air
mouth
- Tube that delivers air from the mouth going to the trachea
pharynx
3 types of pharynx
nasopharynx, oropharynx, laryngopharynx
among the 3 types of pharynx which is most superior \?
nasopharynx
pharynx that is located to posteriorly to the mouth
oropharynx
where is the laryngopharynx located?
inferior to oropharynx
- Located inferior to the pharynx
larynx
- a hollow area between the facial bone that help regulate the temperature and humidity of the air
sinuses
what are the different types of sinuses
frontal, maxillary, ethmoid, spenoid
which sinus is the most superior?
frontal
which sinuses are the biggest & smallest?
b - maxillary, s - ethmoid
which sinus is the most posterior?
spenoid
- passage that connects the throat and the lungs
trachea
where is the trachea located?
behind the esophagus
what are alveoli?
tiny-air sacs that look like grapes
- contains almost 5,000,000 alveolus
lungs
what are the lobes of the lungs?
r - superior, middle, inferior
l - superior & inferior
what do you call the division of lungs?
fissures
- Contains all thoracic organs except lungs
mediastinum
which organ occupies most of the mediastinum?
heart
what are the other organs located in the mediastinum?
thyroid, thymus glands, nervous and lymphatic tissues
parts of mediastinum
- Anterior mediastinal masses
- Middle mediastinal masses
- Posterior mediastinal masses
- In infants, _______ appears WIDE because the _____ is normally large in a healthy infant
thymus
what projection/s fills the anterior portion of the mediastinum?
PA & LAT
- PA & LAT fills the anterior portion of the mediastinum w/c refers to as _____
SAIL SIGN
another name for pneumomediastinum
spinnaker sign or angel wing sign
another name for spinnaker sign or angel wing sign
pneumomediastinum
a kind of condition wherein there’s there’s disruption in the esophagus/airway and air is trapped in the mediastinum
- MEDIASTINAL EMPHYSEMA or pneumomediastinum
when pneumomediastinum is extensive, air may pass from the mediastinum into the subcutaneous tissue of the chest/neck
subcutaneous emphysema
how can a diagnosis of subcutaneous emphysema be made?
feeling air bubbles in skin of the chest/neck
what kind of imaging is commonly used especially in pediatrics
CR & DR
harder than normal to penetrate (any condition that adds fluid/tissue to the chest)
additive pathologies
easier than normal to penetrate (any condition that increases the aeration of the chest/ decreases the parenchymal tissue of chest)
SUBTRACTIVE PATHOLOGIES
what are the standard techniques for the respiratory system
PA & LAT 72 in SID
