Biology Lesson 1
Keeping Healthy
Learning Objectives:
In this chapter you will learn:
 Heart - Position and structure, Cardiac cycle, Control of heart rate, Cardiac output,
Blood pressure, Blood supply to the heart
 Double circulation - Pulmonary and systemic circulation
 Blood vessels - Artery, veins and capillary, Exchange of materials between blood
and body cells
 Blood - Composition of blood (plasma and cell particles)
 Lymph and lymphatic system - Formation and role of lymph, Components of
lymphatic system
 Diseases of circulatory system – Atherosclerosis, Coronary heart disease,
Hypertension
 Processes of nutrition in human
 General plan of the human digestive system - Roles of various parts of the
alimentary canal and accessory glands
 Structure and care of teeth
 Absorption digested products - Absorption of water-soluble and fat-soluble
substances, Structure of small intestine in relation to absorption
 Assimilation of digested products
 Importance of dietary fibre
