Chapter Overview
Chapter 3 Immunity And Diseases introduces Grade 7 students to the human body's intricate defense mechanisms against invading pathogens like bacteria, viruses, and fungi. Students explore the concept of biological immunity, distinguishing between non-specific innate immunity (skin, mucous membranes, phagocytes) present from birth and pathogen-specific adaptive immunity acquired over time.
The chapter provides an essential understanding of antibody formation, explaining how white blood cells (lymphocytes) recognize antigens and produce specific Y-shaped protective proteins. It contrasts naturally and artificially acquired active immunity with passive immunity (such as maternal antibodies passed through breast milk or antiserum injections), highlighting practical lifestyle choices to boost immune system strength.
Furthermore, the chapter examines major infectious diseases relevant to Pakistan, including viral infections (COVID-19, Dengue fever, Hepatitis-B) and bacterial infections (Typhoid). Students study pathogen transmission vectors, clinical symptoms, treatment protocols, and preventive measures. Mastering these biological health concepts prepares FBISE students for conceptual SLO board exam questions.
