DIAPHRAGM

• A flat muscle that controls breathing
• Is the primary muscle used in the process of inspiration, or inhalation
• A large, flat sheet of muscle that pulls air into the lungs and pushes out air

CAPILLARY

• A tiny blood vessel
• They measure around 5-10 micrometers in diameter

ALVEOLI

• Thin-walled air sacs within the lungs
• The main function of the alveoli is the exchange of carbon dioxide for oxygen in the lungs
• Small, thin sacs at the end of bronchus where gas exchange happen ( oxygen --------> co2)

DIFFUSION

• The movement of particles from areas with high concentrations to areas with low concentrations
