REET Level 2 study notes
Human Body and Health
Human Body and Health for REET Level 2 science covers body systems, food components, balanced diet, deficiency diseases, microorganisms, communicable diseases and prevention. Study it as upper-primary school science: classify disease routes, connect prevention to cause, use safe food and hygiene activities, and distinguish health from mere absence of fever. The strongest answers protect children, avoid diagnosis, and use verified RBSE and NCERT language.
Key points
- RBSE names diseases spread by microorganisms, prevention, body systems, food components, deficiency diseases and balanced diet.
- Balanced diet means essential nutrients, roughage and water in the right amount for growth and development.
- Communicable diseases are pathogen-caused and can spread from person to person.
- Non-communicable diseases do not spread by contact; some link to lifestyle, environment or nutrient deficiency.
- Microorganisms include bacteria, fungi and protozoa; viruses reproduce only inside host organisms.
- Health includes physical, mental and social well-being, not just absence of disease.
- Good classroom activities classify food, disease routes and prevention without shaming children.
- MCQ traps often confuse prevention with treatment, deficiency with infection, and all microbes with harmful microbes.
