respiration and breathing

These two processes have been taught since Primary 3. However, some students in Secondary 1 can't even tell the the difference between the two.
Breathing:
This process is much easier than respiration. Breathing is the process in which living ,things take in air, and exhale air. Evaporation involves the he mouth, the nose and nostrils, the pharynx, the larynx, the trachea, the bronchi and bronchioles, the lungs, the diaphragm, and the terminal branches of the respiratory tree, such as the alveoli. To take in air, our diaphragm moves down, creating a vacuum to suck up air from the surroundings.
Respiration:
This process involves all the cells in our body, not just in the respiratory system. during respiration. There are two types of respiration, anaerobic and aerobic respiration.
Anaerobic respiration is more complicated than aerobic respiration. It breaks down oxygen and glucose into carbon dioxide and energy.
Aerobic respiration breaks down glucose into energy.
