asthma

carbon dioxide from the blood.
Inhale
Breathing in to take in oxygen
Ligament
Joins to bones together
Lung volume
The amount of air your lungs can hold
organ
A group of tissues working together to perform a function.
oxygen debt
Extra oxygen required after anaerobic respiration to break down
lactic acid.
ribcage
The bones that protect the lungs.
skeleton
All the bones in an organism
trachea
A large tube running down the throat and connecting the mouth
and nose to the lungs.
