Respiration

• Oxidation of glucose in order to provide energy for maintenance, repair etc.
• As earlier said, respiration is required for the process of the synthesis of ATP
• This energy is of vital importance as it is used by cells for carrying out their functions

Excretion

• Removal of metabolic wastes from the body
