Respiration Flashcards
What is the definition of Lobule?
Lobule is a cluster of aveoli
what is the outlining of the aveoli called?
surfactant
what does the surfactant do?
it keeps the aveoli open
what goes in and out of the aveoli?
Co2 comes out o2 goes in aveoli
What does blood give and take from aveoli?
Blood gives aveoli Co2 and takes o2
What does blood give and take from cell?
Bloog gives cell o2 and takes C02
what is the exchange between the blood and aveoli called?
external respiration
what is the exchange between the blood and cell called?
Internal respiration
What is it called when Co2 comes out from aveoli and o2 goes in?
breathing
What is the formula for the cellular respiration?
o2 + glucose = ATP + Co2 + H20
what does red blood cell carry?
red blood cell carries gas
what is the most important structure to make red blood cell?
iron
what does red blood cell contain inside them?
hemoglobin
what does hemoglobin contain?
protein + iron heme group
what is hemoglobin able to do?
It is able to max gas transport and it has a high affinity for o2 and Co2
what is three things to conditioning the air?
clean, warm, and moist
what does the nasal hair do?
it traps debris to clean air
what is mucous made of?
water
what does the mucous do?
it trap debris. and moisterizes the air
what are cilia?
they are hair lace structures
what direction is cilia moving?
upwards
what do blood vessels do?
it warms air as it passes
what does the decrease in volume create?
positive pressure
does the fluild go in or out when there is decrease in volume?
the fluid goes out
what does the increase in volume create?
negative pressure
does the fluid go in or out when there is increase in volume?
the fluid goes in
when the rib cage moves, what does it change?
it changes the volume of the chest thoracic cavity
what makes the rib cage move up and down?
inter costal muscles
what are inter costal muscles?
muscles between rib cage
what happens when the diaphragm contracts?
increase in volume but negative pressure
what happens when the diaphragm relaxes?
decrease in volume but positive pressure
what does inhalation need?
energy
inhalation is always…..
active
what happens in inhalation?
air goes in (increase volume to create negative pressure)
what is opposite of intercostal?
external
what does intercostal muscles do in inhalation?
muscles cotract movinf rib cage UP then OUT so air goes in
For inhalation, what does the diaphragm do?
it contracts moving diapragm down
when diapragm contracts, what happens?
air goes in
exhalation is…..
normal and passive
what happens in exhalation?
air goes out (decrease in volume creating positve pressure)
what does intercostal muscles do in exhalation?
muscles relax and rib cage drops DOWN and IN so air goes out
For exhalation, what does the diapragm do?
it relaxes moving diapragm up
In forced exhalation, what does the intercostal muscle do?
muscles contract moving rib cage down and in with forced (down down v ++ p)
what happens when air is being forced out?
abdominal muscles will contract pushing diaphragm up with force (down down v ++ p)
