9.2.1—Structures of the mammalian heart
- Identify in diagrams and images the structures of the mammalian heart, limited to: muscular wall, septum, left and right ventricles, left and right atria, one-way valves and coronary arteries
9.2.2—Blood is pumped away from the heart
- State that blood is pumped away from the heart in arteries and returns to the heart in veins
9.2.3—Activity of the heart may be monitored
- State that the activity of the heart may be monitored by: ECG, pulse rate and listening to sounds of valves closing
9.2.4—Effect of physical activity on
- Investigate and describe the effect of physical activity on the heart rate
9.2.5—Coronary heart disease in terms
- Describe coronary heart disease in terms of the blockage of coronary arteries and state the possible risk factors including: diet, lack of exercise, stress, smoking, genetic predisposition, age and sex
9.2.6—Roles of diet and exercise in reducing
- Discuss the roles of diet and exercise in reducing the risk of coronary heart disease
9.2.7—Atrioventricular and semilunar valves
- Identify in diagrams and images the atrioventricular and semilunar valves in the mammalian heart
9.2.8—Relative thickness of: (a) the muscle
- Explain the relative thickness of: (a) the muscle walls of the left and right ventricles (b) the muscle walls of the atria compared to those of the ventricles
9.2.9—Importance of the septum in separating
- Explain the importance of the septum in separating oxygenated and deoxygenated blood
9.2.10—Heart function
- Describe the functioning of the heart in terms of the contraction of muscles of the atria and ventricles and the action of the valves
9.2.11—Effect of physical activity on
- Explain the effect of physical activity on the heart rate
