1.1 Respiratory Physiology intro Flashcards
what is interal respiration
biochemical processes such as glycolysis
What is external respiration?
normal respiration e.g. breathing
what is the pulmonary circulation
It includes lungs and the air and blood delivered to it, does not include heart
what is included in systemic circulation
heat and tissues
What is the function of the pulmonary artery?
carries deoxygenated blood to the lungs from the heart
What is the function of the pulmonary vein?
carries oxygenated blood to the heart from the lungs
What is exchange phase 1,2 and 3
1- air from the atmosphere to lungs
2- from lungs to blood
3 - between blood and cells
how much gas is exchanged in the lungs each minute for
1.CO2
2. O2
1.200
2.250
pharynx functiojn
connecting point of airway of the mouth and nose, also dampens the air
trachea made up of
stiff cartiladge rings
epiglottis function
Stops food form entering the trachea when you swallow , covers trachea
Bronchus
Has air move from the trachea into the lungs
larynx function
voice box
What structure splits the upper and lower respiratory tract
the larynx ( this is in the upper)
What is in the:
A. Primary
B. Secondary
C. Tertiory
airway
A. lung
B. lobe
C. Pulmonary segments
What are the names of the lobes in the left and right lung
Left - Superior, middle, inferior lobe
right, superior and inferior
What are the names of the fissure in the left and right lung?
Left - Horizontal fissure (between superior and middle
oblique fissure - between inferior and middle lobe
what part of the airway has the most resistance
trachea and primary bronchoil, due to smalller crhoss sectional area
What is inclued in the Conductionn zone
Trachea, primary bronchi and smaller bronchi, and bronchioles
What is included in the respiratory zone
alveoli
difference between bronchi and bronchioles
bronchioles lach cartilage discs
How many primary bronchi are there
2
what is the function of a type 1 and type 2 cell in the aveloi and where are they found
type 1: gas exchange, large cell on making up most of aveloi
type 2 : synthesize surfactant ( smaller cells on outside of type 1.
what does the sufficant do
coat the inside of the aveloi and create tension
