9 Discover Biology Checklist: Blood and Blood Circulation Main Objec+ves: 1 To name the different components of the blood and describe their characteris4cs and func4ons 2 To explain the process the closing of a would 3 To describe the anatomy of your heart 4 To compare the tree main types of blood vessels and their func4ons 5 To trace a path of blood as it circulated on your body 6 To explain how a heart disease develops and how it can be prevented 1 Name the different components of the blood and describe their characteris4cs and func4ons! Component Descrip5on Func5on plasma about 55 per cent dissolves and transports glucose, amino acid yellowish substance, mostly and fat, waste substances, plasma proteins, water hormones, vitamins and an4bodies red blood cells about 44 per cent transport oxygen bound in iron molecules in the red and wheel shaped, no hemoglobin nucleus haemoglobin (containing iron) & white blood cells less than 1 per cent destroy germs and break up dead body cells phagocytes can change shape leave capillaries, consume germs / damaged cells lymphocytes fight against germs and toxins by producing specific an4bodies* platelets less than 1 per cent s4ck to the rough edges of the wound and form small pieces of specialized cells a kind of patch over it, release substances from the bone marrow with ac4va4ng cloGng factors irregular shape, no nucleus *An4bodies are proteins which can either destroy the germs and other dangerous substances directly or make them s4ck together, so that they can be eaten by phagocytes. 1  9 Discover Biology 2 Explain the process of the closing of a wound! 1. Blood vessels are damaged and blood flows out of the damaged vessels. 2. The walls of the blood vessels contract to make the opening smaller. 3. The platelets s4ck to the rough edges of the wound and form a kind of patch over it & 4. The platelets and damaged cells release substances to start the cloGng process - 5. A special fluid protein (fibrinogen) changes its form to become solid fibre (fibrin). 6. Fibrin creates a net across the wound, enclosing damaged 4ssue, white and red blood cells and also platelets. 7. The result is a blood clot, which stops the bleeding. 8. The blood clot hardens to become a scab. 9. Beneath the scab a new layers of skin slowly grows and aSer several days the scab falls off.
