2. DIFFERENCES BETWEEN INHALED AND EXHALED AIR
BREATHING
the process of taking in (inhaling) and pushing out air (exhaling)
DIFFERENCES BETWEEN INHALED AND EXHALED AIR

3. WHAT HAPPENS DURING INHALATION AND EXHALATION

4. GASEOUS EXCHANGE Gaseous exchange
Gaseous exchange is described as the exchange of gases through moist surfaces called the respiratory surfaces.
Gaseous exchange occurs by the process of diffusion

10. RESPIRATION
Respiration is a very important process occurring in each cell.
Respiration is described as the process by which food is broken down completely or incompletely to produce energy.
There are two types of respiration:
Aerobic respiration
Anaerobic respiration
