RESPIRATORY SYSTEM Prepared by: Rouse Leanne Nicolas RESPIRATION • A vital process of all living organisms where the chemical energy is made available for the life activities by the oxidation of food. • In cell, respiration takes place in the Mitochondria. RESPIRATION • The energy produced in respiration is used as: Chemical energy Light energy Mechanical energy Electrical energy RESPIRATION • The energy produced in respiration is used as: Electrical energy Sound energy Heat energy BREATHING VENTILATION • The entrance •The and exit of air movement into and from of air to and from the the lungs. alveoli.
