6ocal cords#

It has t!o nctions' a passa8e!ay

or air and as a 6oice 7ox#

%n8

One o t!o spon8y9 sacli"e

respiratory or8ans in most

6erte7rates that are in the chest

ca6ity#


7/32

Its main nction is to oxy8enate

the 7lood 17y the inta"e o oxy8en9

then the otpt o car7on dioxide2#

Bronchi 1let and ri8ht 7ronchs2

s7di6ides into smaller and smaller

7ranches 5st li"e tree 7ranches

that 8et smaller as they 8ro! p

and ot#

here rom otside9 it has 7een

!armed p to 7ody temperatre9

fltered and moistri:ed#


11/32

&l6eoli

& tiny9 thin air cells 1or sacs2 in the

ln8s that resem7le 7nches o

8rapes#

It is !here the exchan8e o oxy8en

and car7on dioxide ta"es place#

They 8i6e p oxy8en and ta"e

car7on dioxide9 !hich then exits

the 7ody the same !ay it came

1thro8h the 7ronchioles and

7ronchi9 p the trachea9 then ot

the moth or nose2#
