2During breathing in:
(1) Air enters the breathing system through the nose (or the mouth)
(2) Air travels along the [blank_start]trachea[blank_end] and then the two [blank_start]bronchi[blank_end].
(3) Air travels along smaller and smaller tubes.
(4) Air reaches the [blank_start]air[blank_end] [blank_start]sacs[blank_end] at the end of the smallest tubes.- Atrachea

3Gaseous exchange inside the lungs
The trachea branched to two [blank_start]bronchi[blank_end] (singular: bronchus).
Each bronchus divides into smaller and smaller tubes, ending in a large number of [blank_start]air[blank_end] [blank_start]sacs[blank_end].
The air sacs are surrounded by tiny blood vessels ([blank_start]blood[blank_end] [blank_start]capillaries[blank_end]).
The blood in the blood vessel flowing from other parts of the body carries higher [blank_start]carbondioxide[blank_end] content and lower [blank_start]oxygen[blank_end] content.
Gaseous exchange occurs between through the thin wall of the air sac and blood vessels.
Carbon dioxide leaves the [blank_start]blood[blank_end] to the [blank_start]air[blank_end] and oxygen enters the blood from the air.- Abronchi
