29 slides cover: respiration.
By the end of the powerpoint students would have covered /:
4.4.2.1 Aerobic and anaerobic respiration
Students should be able to describe cellular respiration as an exothermic reaction which is continuously occurring in living cells.
The energy transferred supplies all the energy needed for living processes.
Respiration in cells can take place aerobically (using oxygen) or anaerobically (without oxygen), to transfer energy.
Students should be able to compare the processes of aerobic and anaerobic respiration with regard to the need for oxygen, the differing products and the relative amounts of energy transferred.
Organisms need energy for:
• chemical reactions to build larger molecules
• movement
• keeping warm.
Aerobic respiration is represented by the equation: glucose + oxygen --> carbon dioxide + water
Students should recognise the chemical symbols: C6H12O6, O2, CO2 and H2O.
Anaerobic respiration in muscles is represented by the equation: glucose lactic acid
As the oxidation of glucose is incomplete in anaerobic respiration much less energy is transferred than in aerobic respiration.
Anaerobic respiration in plant and yeast cells is represented by the equation:
Glucose --> ethanol + carbon dioxide
Anaerobic respiration in yeast cells is called fermentation and has economic importance in the manufacture of bread and alcoholic drinks.
**4.4.2.2 Response to exercise **
During exercise the human body reacts to the increased demand for energy.
The heart rate, breathing rate and breath volume increase during exercise to supply the muscles with more oxygenated blood.
If insufficient oxygen is supplied anaerobic respiration takes place in muscles. The incomplete oxidation of glucose causes a build up of lactic acid and creates an oxygen debt. During long periods of vigorous activity muscles become fatigued and stop contracting efficiently.
(HT only) Blood flowing through the muscles transports the lactic acid to the liver where it is converted back into glucose. Oxygen debt is the amount of extra oxygen the body needs after exercise to react with the accumulated lactic acid and remove it from the cells.

23 slides covering the The heart and blood vessels.
By the end of the powerpoint students would have covered:
Students should know the structure and functioning of the human heart and lungs, including how lungs are adapted for gaseous exchange.
The heart is an organ that pumps blood around the body in a double circulatory system. The right ventricle pumps blood to the lungs where gas exchange takes place. The left ventricle pumps blood around the rest of the body.
Knowledge of the blood vessels associated with the heart is limited to the aorta, vena cava, pulmonary artery, pulmonary vein and coronary arteries. Knowledge of the names of the heart valves is not required.
Knowledge of the lungs is restricted to the trachea, bronchi, alveoli and the capillary network surrounding the alveoli.
The natural resting heart rate is controlled by a group of cells located in the right atrium that act as a pacemaker. Artificial pacemakers are electrical devices used to correct irregularities in the heart rate.
The body contains three different types of blood vessel: • arteries
• veins
• capillaries.
Students should be able to explain how the structure of these vessels relates to their functions.
Students should be able to use simple compound measures such as rate and carry out rate calculations for blood flow.
