respiration- alveoli Flashcards
respiration
exchange of gases (O2 in and Co2 out)
where does the O2 go
every cell in the body
what happens with CO2 and O2
the cells swap in the alveoli
where does cellular respiration ‘swaping’ take place
in alvioli
what does the membrane have to be to be able to diffuse
thin and moist
what is the thin moist membrane that covers the lungs
pleura
what is the problem with asthma
CO2 can get out
what are the 2 nose holes called
nostrils
why do we have 2 nostrils
so we get air both ways
what is the cartilage that divides the nose called
septum
what is it called when the septum is crooked
deviated septum
why is breathing through the nose better than breathing through the mouth
because the air is warmed and filtered
what are the hairs in the nose called
cilia
what is the job of mucus in the nose
wraps all the stuff up
describe the structure of mucus
slimy protein
what makes up the throat
esophagus and trachea
where is the esophagus located
in the back of the throat
where is the trachea located
in the front of the throat
how big is the trachea
5”
what makes up the trachea
rings of cartilage
what is the trachea
windpipe
what is the epiglottis
flap over opening in the trachea
flap over opening in the trachea
epiglottis
larynx
voice box holding vocal chords
where is the larynx located
trachea
what does the larynx hold
vocal cords
how many pieces of cartilage are in the trachea
15-20
function of cilia
catch dust and dirt
where is the adams apple located
trachea
what is the adams apple caused by
testosterone
adams apple
large piece of hyaline cartilage
what type of cartilage is in the adams apple
hyaline
hyaline cartilage
in the adams apple, shiny
why can you do to decrease the size of an adams apple
shave it
do women have an adams apple
yes
right bronchus
shorter, wider, and straighter than the left
disease that affects the bronchi
bronchitis
covering over lungs
pleura
pleurisy
infected pleura
how many lobes are in the right lung
3
how many lobes are in the left lung
2
symptoms of pleurisy
hard to breath, chest pain
how do you get pleurisy
damp cold places, sitting on the cold ground, mechanics
bronchioles
little branches of bronchi
what happens to the bronchioles in asthma
they cinstrict
alvioli
air sacs surrounded by capillaries
function of alvioli
increase surface area, diffusion
what other than alveoli, increase surface area
villi
structure of alvioli
a bunch of grapes with thin walls for diffussion
how many alveoli are in each lung
1 milion
