What are the effects of getting too little oxygen? What is respiration?
3
The body changes food into a form which can be carried around the body. This substance is called GLUCOSE. What type of fuel is required by the body? When glucose reacts with oxygen a LOT of energy is produced. Some of this energy is released as heat while the rest is used by the cells. Glucose contains energy. The cells do NOT catch fire.
4
FOOD (GLUCOSE) OXYGEN + from digestive system from breathin g system WATER CARBON DIOXIDE++ ENERGY USEFUL!waste product exhaled We can now write out the full equation for RESPIRATION. What is respiration? RESPIRATION is the process which releases energy from food. This is NOT the same as breathing. Combustion is different because it is NOT a controlled reaction. Respiration IS a controlled reaction which SLOWLY releases energy from food in the CELLS.
5
Aerobic Respiration AEROBIC When the body can supply the cells with the oxygen and food that they need, We say it is performing AEROBIC respiration. The equation for this is: Glucose + oxygen Carbon dioxidewater Glucose + oxygen Carbon dioxide + water + ENERGY Anaerobic Respiration When the body CANNOT supply the cells with the oxygen and food that they need, then the body must perform anaerobic respiration. The release of energy WITHOUT oxygen: Glucose Lactic acid Glucose Lactic acid + a little energy

Inhalation (When we breathe in we inhale)
7
The Alveoli The outside of the alveoli is covered with tiny blood vessels. Oxygen makes its way into thousands of special air sacs collectively called the ALVEOLI.
