Phagocytosis 1. Watch the animation of phagocytosis on the screen 2. Use the craft materials to model Phagocytosis 3. On a revision card, draw a series of diagrams showing phagocytosis and make sure that you label » White blood cell » Pathogen Add a sentence describing what the white blood cell does

White Blood Cells Level 4 Level 6 How do white blood cells protect the

White Blood Cells Level 4 Level 6 How do white blood cells protect the body? Also explain why we can catch flu a second time

How do white blood cells protect the body? • Produce anti toxins Level 4

How do white blood cells protect the body? • Produce anti toxins Level 4 – Which break down toxins produced by bacteria • Produce antibodies – Which attach to the antigens on the pathogen – And kill the pathogen • Carry out phagocytosis – Where the white blood cell surrounds, engulfs and digests the pathogen • Influenza virus mutates Level 6 • Antigens change • White blood cells produce antibodies that no longer fit

Antibiotics: Answers Level 4 • They are medicines that kill bacteria • We can prevent them from bacteria becoming resistant to antibiotics by washing our hands, taking the full course and not prescribing them for minor infections • • Bacteria that are affected by the antibiotic mutate They can now survive treatment with the antibiotic They reproduce by binary fission And pass the mutated gene onto their offspring Level 6

Vaccinations - Collect a small table sheet and fill it in What does a vaccine contain? Dead or inactive pathogens What does a vaccine make the patient make? Antibodies What will antibodies do to the invading pathogen? Kill it If you meet the pathogen again, give 2 ways that your response will be different • More antibodies made • Antibodies made faster Draw the shape of the graph that would show the difference in antibody production before and after a vaccination
