Respiration System Flashcards
Respiration
is the process of exchanging gases between the atmosphere and body cells.
What is Ventilation?
breathing
What is external respiration?
gas exchange- load O2/ unload CO2
What is respiratory transport?
gases in blood transported from lungs to body cells and back to lungs
What is internal respiration?
gas exchange load CO2/ unload O2
What is Oral Respiration?
use of O2 to produce energy
What organs are in the Upper Respiratory Tract?
- nose
- nasal cavity
- nasal conchae
- paranasal sinuses
- pharynx
- larynx
What organs are in the Lower Respiratory Tract?
- trachea
- bronchial tree
- lungs
What is the Upper Respiratory Tract made of?
lined w/mucous
seudostratified ciliated ET w/goblet cells
Function of the Upper Respiratory Tract?
trap & transport foreign particles warm & moisten incoming air
How does the Cilia act in the Respiratory System?
Cilia move mucus and trapped particles from the nasal cavity to the pharynx to be swallowed.
Another Word of Nostrils?
External Nares
What is your nose made of?
Bone and cartilage with internal hairs called vibrissae
Function of the nose?
Traps large particles
What Seperates the Nasal Cavity?
Nasal Septum
What is the Nasal Cavity Made of?
Bone and cartilage lined w/mucus membranes
Nasal Cavity Function
warms/moistens incoming air
olfactory reception
resonating chambers for speech
Another Name for Nasal Conchae?
Turbinates
Where does the nasal conchae lie?
Within the nasal cavity
What sections are the nasal conchae made into?
Superior, Middle, Inferior
What are your Paranasal Sinuses filled with?
Air
Bones of the Paranasal Sinus?
maxillary, frontal, ethmoid, and sphenoid bones
Function of the Paranasal Sinus?
reduce weight of skull & resonance chambers
What is your Pharynx lined with?
Mucus Membranes
Function of Pharynx
Passageway for air/food
Three Parts of the Pharynx?
a) nasopharynx
b) oropharynx
c) laryngopharynx
What are the larynx lined with?
ciliated mucous membrane
What are the 2 folds and they’re functions?
a) upper folds- false vocal cords- plays no part in vocalization
b) lower folds- true vocal cords
